Missing Subtraction Parts Free Math Unit - Subtrahends and Minuends

Subtraction with Missing Minuends or Subtrahends 

A Free Teaching Unit

Want MORE free teaching and practice units? Check out my math freebies page!

Last week I released a unit on teaching addition with missing addends - and today I am giving you the same thing, except with strategies for subtraction equations with missing parts!

This is an important skill for kids to learn, definitely by third grade (but is usually taught in first and second grade). It will be useful when they encounter higher math problems with missing parts or facts in problem-solving. It's really not a difficult concept to teach either - although your learners may need to spend more or less time on it depending on their learning style. 

I make these units to teach my own youngest daughter who does not always do very well with the traditional math textbooks - these units are short, to the point, and have plenty of colouring opportunities (which she loves - and they help her absorb information better!) Of course, even if your learner does not learn in the same way, you can use these units to quickly cover concepts that you feel might be missing from their math skills or curricula.

Explanation Posters and Teaching Aids

I always try to include some sort of teaching aids in most of my units. These are meant to be read out loud to kids, but you could also use them to teach yourself teaching methods and then teach your kids in your own way. For example, if you have a learner who learns best through hands-on activities, you could read through how to teach solving a subtraction equation with a missing subtrahend, then teach them using counters or toys or even online math manipulative simulator.

Just as in my addition unit, I included a sheet to teach using these methods with problem-solving as well! 

Practice, practice and more practice sheets!

We all know that practice in math concepts is SO important so I included a few worksheets for each strategy, including problem-solving. I also included some blank worksheets that could be printed out and written in, or edited in Adobe or a PDF editor to write in your own equations or problems. 

If you're teaching in a classroom, you could write some problems on the board or projector for kids to copy down. If you're homeschooling, you could write down the problems for your kiddo to solve or have them write them in a pdf editor themselves. There are many ways to use these sheets to get in plenty of practice!

Problem Solving

As I mentioned above, I include problem-solving in this unit to show kids how to apply the strategies they've learned to problem-solving, or real-world situations. Sometimes it is difficult for kids to take a math skill and apply it to a word problem, so it is super important to help them practice this.

I have also included two problem-solving situations for them to practice with, as well as blank worksheets you could fill in on your own - or even have your learners create their own problems for YOU or their classmates to solve!

Free Math Unit Missing Addends

Free Math Unit Missing Addends 

It's a new free math unit! Want MORE free math units for all grades and ages? See my math freebie page here!

Solving addition equations with missing addends is an important skill for kids to have in their math toolbox. Having this skill down for math tests or progress reports is important, but it's even more important for real-life situations. 

In this unit, learners will cover how to use counting up or subtraction to solve addition equations with missing addends. It's a unit focused on second-grade skills, but I've included worksheets that older kids can use too.

Pre-Knowledge Posters

Before starting this unit, kids should know how to add and subtract, and cont within 100. It is also very helpful if they know how to regroup in addition and subtraction problems - but it is not necessary. With most of the unit younger kids could use the counting-up strategy. Another helpful skill to have is for kids to understand the commutative property of addition - that is, they should know that 5 + 3 and 3 + 5 will both give the same sum.

Just to help with these concepts to remind kids if they need it, I have included some posters that go over these concepts.

How to Solve Addition Equations with Missing Addends

For younger kids who might be at a grade k-2 level, you may want to start by teaching them the counting-up strategy. In this strategy, kids will solve the addition equations by counting up from the addend they know to the sum. Even if your kids are older, teaching them this strategy is a great way to begin teaching this concept because it is showing them that they are finding the difference between the two numbers - which leads into the second strategy of subtraction.

The subtraction method teaches learners to solve missing addends equations using the opposite operation of addition. For example, if we want to find out the missing addend in the equation 5 + ? = 12, we could figure out the difference between 12 and 5 and get out answer. 12 - 5 = 7, so we know that the missing addend is 7. 5 + 7 = 12.

Missing Addend Worksheets

I have included a few options for worksheets in this unit. First, there is a worksheet for kids to practice the counting-up method with. The rest of the worksheets use subtraction method and include mainly 2-digit numbers. You'll also find some extra worksheets with 3 and 4 digit numbers that older kids could use to practice these strategies, as well as a blank worksheet.

 Problem-Solving with Missing Addends

One of the most important things to show kids in math is how it can be applied to real life. I this unit, I included two very simple problem solving questions that they can use their new strategies to solve. Counting up or subtraction could be used for both of these problems, as the highest number is 34.

Free Math Unit Partitioning Shapes and Early Fractions

 Free Math Shape Partitioning and Fraction Kit

Want more math freebies? Check out my math freebie page here!

I have another wonderful math kit for you this week - a perfect release before my free fractions kit comes out soon!

This unit is all about partitioning shapes, an important first step in teaching kids about fractions. It's a quick unit, but a full one. It includes simple explanations, task cards and a hands-on activity, worksheets, and even 3 problem-solving questions for your kids to solve!

Take a look...

The first part of this unit will review the basics of plane figures (2D shapes). It includes a simple poster that shows different types of basic shapes and explains what sides and vertices are. 

The unit then dived into using basic shapes to build other shapes with some fun task cards and shape pieces. You could, of course, use your own pattern blocks, but if you do not have any on hand your kiddos can use and color the included ones. They may even like to glue them into a math journal or make more pictures with them afterward. 

The reason for teaching this concept is so that children can see how a shape is built and how it can be divided into different shapes. This will help them partition shapes now and understand fractions better later on in their learning journey.

After this, learners will explore the basics of dividing a shape into equal parts, halves and fourths. They'll get their first look at what a written fraction could look like and what a drawing looks like. When teaching this unit, do not focus too much on the written fraction (eg 1/2 or 1/4), but instead focus on what it means to divide something into equal halves or equal fourths/parts.

To reinforce these concepts I have included a few different worksheets.

• Partition the shapes into halves
• Partition the shapes into fourths
• Colour in the fraction of the shape (eg two fourths)
• 3 problem-solving questions

I really love these types of problem-solving questions because they give kids a chance to show their understanding. They are asked to not only write an answer but also to draw their answer to prove their thinking. This is not only a great math skill but a way for you to assess if they lack understanding in any area of the unit.

Of course, just as in my other math kits I have also included helpful links to videos that explain these concepts to kids as well as online practice games so that they can practice them anytime!

I really hope that you and your kids enjoy this one and that it helps you in your homeschool or classroom! If you have any questions, please feel free to reach out.

Free Division Kit to Teach Division for Homeschool or Classrooms

Free Division Kit to Teach Division

Want more math freebies? Check out my math freebies page here!

Division is one of those concepts that we think is easy for kids to understand - it's just like sharing! But when we move from teaching sharing between two friends to sharing 144 between 12, kids can get confused quickly - can you blame them? I always like to take things slow when I'm learning a new concept - I need to see it, feel it, and really GET it before moving on.

That's exactly how I designed this division kit to be used. Inside this 60-page unit you'll find everything you need to teach kids division, in a paced order that makes sense.

The unit begins with links to video explanations you can use, as well as online games you can use to practice division later on. If you're not familiar with division concepts yourself, you may want to watch the youtube video I recommend in the unit - Blooming With Ms B explains all the concepts ina  few minutes. It's great for kids, teachers or parents (or both together!). 

After you've gone over skip counting as a base, I recommend playing the 'cookie game' included in the unit. It is SO much fun and really helps kids see how division could work visually. There are array mats, standard algorithm worksheets, flashcards, and more!

I have included simple explanations and posters inside the unit as well. You could hang these on the wall, project them onto a screen, or have kids glue them into a notebook for their own reference. 

There is a vocabulary poster too that you can refer to since many math problem-solving questions will have this vocabulary in them. It can really come in handy later on!

 Finally, there is plenty of ways to practice division in this unit. There is the cookie game, arrays mats, worksheets and flashcards that can be used together to practice the facts. Once kids have practiced the division using the given methods a few times and really understand the concept, these worksheets are a great way to get in some practice every week. 

You can also add in the online games here. There are some really fun ones that my own kids enjoy. If you have a tablet or phone you let your kids play on, there are also plenty of free apps that you can find to practice division and multiplication facts! (You can grab the free multiplication kit I made here!)

Free Regrouping 2 and 3 Digits Math Center

Free Regrouping 2 and 3 Digits Math Center

Following my addition with regrouping posters and workbook set, I wanted to share this quick center I made with you all too! A great way to get kids to pay closer attention to whether or not they need to regroup when adding, this center is easy to print and quick to set up.

You can choose to laminate it and use it as a full-class or homeschool center, or you could choose to have cut and glue the equations on.

 Learners will need to sort the 2 or 3 digit equations onto the correct mats - regroup or don't regroup. I made these especially for my youngest who sometimes regroups when she doesn't need to - I know this sort of practice can really help!

There are color and black and white versions included for you to use. These would pair great with my free regrouping posters too!

Please feel free to use this resource and share the printed version or share with a link to this blog. I hope this helps you and your learners master those math concepts!

Teaching kids how to subtract using the standard algorithm can be a lot simpler when they have a guide to help them through it. Although we usually don't mind doing the teaching, having to repeat the steps over and over again everyday can start to feel a little bit tiring.

That's where I hope these posters will come in handy!

I made these posters to use with my youngest daughter this year - just like these multi-digit addition posters. I wanted her to have a guide to refer to since we often have to go over the steps, and she (like many other kiddos!) can sometimes regroup when she doesn't need to or forgets to change the numbers she borrowed from.

Every poster has color-coded reminders to regroup if they need to and to rewrite their numbers if they need to. I'm hoping that this will help her along until she can master the concept. I also hope it helps your kids or class do the same!

Just as with he addition unit, the examples go up to 6 place values (subtracting within 100 000). After this, kids will probably be able to figure out higher numbers on their own - if not, you can always come back and review!

I really hope this set helps you and your learners! You can download this freebie by clicking on the link below.

Helps kids understand standard algorithm from 2 digits to 6 with regrouping

Want MORE math freebies? See all of mine here!

If you've ever taught a kid or a class multi-digit addition before, then you know how may times you need to go over the order of solving. 

STart with the ones.

Do you need to carry or regroup?

Did you regroup without needing to?

Don't forget to rewrite your numbers!

You can start to feel a little bit like a broken record.

I made these posters, especially for my youngest daughter whom I homeschool and thought you might all appreciate them too! They go over the standard algorithm of addition showing kids how to solve step-by-step with equations using 2 to 6 digits.

All of the posters are colour-coded to help kids not lose their place when following the steps. For example, you can see in the image above that the ones column numbers are all green. The tens are orange, the hundreds red, and so on. This way they know that if they are in the hundreds column, they need to read the red sentence that describes that step.

The instructions are simple and to the point for kids who already know about regrouping (you could use my free regrouping workbook if you feel like you need some help here!)

I find this to be really helpful for kids working on their own. I will keep a copy of the poster we are using on the table next tp my daughter's work, as well as one on the wall. That way, if she forgets what she is doing or needs some guidance, she can easily refer to the poster and follow along.

Quebec History Free Curriculum Book 10 - Iroquoians and the Algonquians

 Free Quebec History Curriculum Unit 10

Comparing the Iroquoians and Algonquians around1500

Want to see all of the other free history units I've made? See this page!

History Mystery number TEN is here! I can't believe we have already gone through 10 units of history together with our kiddos, can you? It really is so simple and fun to dig up the past!

In this unit, kids will cover the progression that requires them to compare the Iroquoian society around 1500 that they have been learning about with the Algonquian society at that same time. The two nations lived very close to one another but lived different lives in many ways. 

Just as they did with the Incas in unit 9, your learners will compare the two societies using a very handy page on Learn QC, but I've made this unit a little simpler to go through. First, if you'd like to spend more time reading about Algonquian society at this time, then by all means take the time to read through more links on the page. To fill out the comparative chart though, kids will just need to click through about two links in each category and try to find some differences OR similarities between the two nations.

This might even be a simple task for them to do since they have been learning so much about the Iroquoians.

There is no project recommendation in this unit like there were in some units, but if you did make a diorama in units 4 and 5 that focused on the Iroquoians, you may want to make one in this unit showcasing the way the Algonquians lived. This would be a great way (or even an alternative) for kids who don't love to write.

As always, these units come with super simple QR codes (or links) to make research super simple.I've also included an extra map in this unit that shows the Algonquian territory and nations camp areas - since they were nomads you'll notice it's a lot broader than the Iroquoians territory that stayed close to the water.

Kids will also get to earn their TENTH badge! That's a pretty big accomplishment too - maybe time for a little celebration? The next unit will focus on French society in Quebec around 1645, so there will be new discoveries to look forward to! After that? We'll look at Canadian Society in new France around 1745, compare changes in French and Canadian societies between 1645 and 1745, and finally, we will dive into comparing New France and the 13 Colonies around 1745. Then it's onto cycle 3 history!

And remember - cycle 2 history goes through grades 3 and 4 so you do have 2 years to go through these units if you'd like to slow down or focus on one topic a little longer.

Free Multiplication Teaching Kit -All You Need to Teach Multiplication

 All You Need to Teach Multiplication in One FREE Kit

Another wonderful math freebie is here! Want more math freebies? Check out my math page here

In January my youngest daughter will be ready to learn multiplication! Although we started a little bit last year we never really dove into writing equations and practicing facts - just learning what multiplication was and how skip counting can make counting collections easier (want to teach counting collections? see my freebie here!)

That is why I came up with this little unit! It has everything you'll need in it to teach multiplication when your child or class is ready to learn the concept.

Teaching Guides, Videos and Online Multiplication Games

Inside the unit, I have included some very simple teaching tips and guides on how to use some of the components of the unit. I definitely recommend starting with skip counting (you can use the included skip counting posters) if you have not already taught this. After that, you can begin with the simple array mat and worksheets included, then progress to equations.

I have also included links to video explanations of multiplication if you'd like to use those, and some free online multiplication games that can be used as practice.

Skip Counting Posters

As noted above, I've included skip-counting posters. You can use these to practice skip counting, and could also use them as an aid to help kids figure out multiplication problems. For example, if they are using the array sheet or an equation sheet and trying to figure out what 5 x 6 is, they can use the 5's skip counting poster to help them count.

Multiplication Flashcards

The included flashcards can be used in a few ways. You could use them alongside the worksheets or mats to pick equations or use them for fact memorization practice. I definitely recommend getting in some good practice with visuals like the array sheet included or this free one before you jump into only writing equations though. The visual part of math is so important as kids progress into more complex math concepts.

Worksheet Practice

I have included a few options for practice here, as well as a link to my blog for more practice freebies (like my very popular Hot Air Balloon Multiplication). In the unit, there are blank array worksheets, an equation worksheet you can use alongside the cards, and multiplication wheels (these are great for pasting into notebooks!).

Quebec History Unit 9 - Incas and the Iroquoians Around 1500

Quebec Curriculum History Mystery 9

Comparing the Iroquoians and the Incas Around 1500

It's time for another history mystery!

Want to see all the other units for cycle 2 elementary? See the history page here!

This unit is a little bit different from the others - but with good reason!

In this unit your learners will put their research skills into use to compare the lives of the Iroquoians in North America and the Incas in South America around 1500. They'll learn how the two societies were so different and get to see that even though these two ancient civilizations did not have as much technology as we do today - they were still organized, coherent, and important societies.

Just like all the other History Mysteries I've made this one uses simple QR codes to do research. In this unit, the first code will lead kids to the very helpful Learn QC website where they will get to compare the Iroquoians and Incas using the links on that page. 

The second link will take them to a youtube video from Freeschool channel that they will use to do a project later on in the unit all about Machu Picchu. However, even if you choose not to do the project, I highly recommend watching the video - it's just a fascinating world wonder to learn about!

Instead of comprehension questions in this unit, I thought it would be great for kids to come up with their own conclusions about the two societies. So I included a graph that is similar to the one on the Learn QC website with the same topics. Their job will be to pick a category within the topic (say, housing in Daily Life) and come up with a way that the two societies were different. I have given an example for them to follow or use in the explanation of the unit. Thanks to the Learn QC website this is super simple task, o it should not take too long to cover the differences - especially if they have been using all of the other units about Iroquoia in the 1500s.

I did write that they should come up with one difference - I know that in third grade that's plenty for most kids. But if you or they feel that they can do more, then, by all means, go ahead! You could write them down or just discuss them.

Finally, I have included a fun project in this unit that kids could choose to do in Minecraft - building a part or complete part of Machu Picchu! I have given an example video on youtube where someone has built their own version in Minecraft (the video has no spoken words - so no worries!) and have provided quite a few free stock photos of Machu Picchu for them to reference as well. Here they can see the types of materials that were used and the shapes of the buildings and homes.

I have also included another map that kids can look at to see where the two societies were located - the Iroquoians and Algonquians in Quebec around the St. Lawrence and the Incas in South America near the Pacific Coast and Andes mountains.

Free Quebec History Mystery 8: Traces From the Past

It's time for another Quebec History Mystery!

Want to see more free History units? Check out my history page here

It's History Mystery #8 - our last unit about the Iroquoians! We'll visit them a bit more in the next unit that compares the Iroquoians with the Inca (an important progression of learning).

In this unit, learners will discover a trace left behind by the Iroquoians - language!

In this unit, kids will follow 3 QR codes. One will lead them to a page with two short paragraphs on LEARN Quebec. Here they'll learn about why language is something in present-day Canada that we have left of Iroquoian culture.

The second will take them to a Wikipedia page that contains places in Canada with Iroquoian names. They will need to find at least 2 and list them.

The third QR code will take them to a really neat Indigenous language translation site that contains some of the Iroquoian language, translated into English. They'll use the chart on this page to do a word hunt!

The worksheets in this unit all help to show kids learning in their portfolios and how they are following and learning the progressions of learning - equal to what is being taught in public schools.

These worksheets are to the point and are always made with my own third and fourth-grade kids in mind. They'll never feel like too much - and if they do just do them over the course of a few days. Taking the time to answer one question per day is actually a great way to slow down and review everything they've learned.

The word hunt in this unit is just for fun so it isn't required, but I highly recommend doing it! Discovering different languages and characters is such an engaging way to dive into history, and it won't take more than 10 or 15 minutes to do.

They may even like to explore the site further and try to write sentences!
 

As always, I include maps and diagrams to keep as a reference or to display in your learning space. I have quite a few of these taped up onto our dining room wall! It's a great way to have the whole family talk about what was learned that day at suppertime. It also helps your kids remember what you talked about and learned.
