## Math Models from Kindergarten to Fifth Grade

I love math models. I haven't always felt this way, but the more I get to know them, the more I just can't get enough of them.

What I like about math models is that they always follow the same rules. This is huge for me because, for most of my education, math was super confusing. I felt like every day we were learning something totally new. I didn't see the connections at all.

In reality, math concepts are all highly related. I believe that math models are a tool for showing students this interrelatedness.

For example, number bonds can be used in kindergarten to show addition and subtraction of one-digit numbers. Kids can even start with manipulatives in the number bond and count to complete addition and subtraction equations.

Once kids have a firm understanding of using number bonds to add and subtract, they can use the number bonds to work with bigger numbers as well. Kids can also use the number bonds to model story problems which may help with story problem comprehension. If they have a framework for how to work with numbers in a story problem, they may have an easier time organizing the information in their heads.

Now that kids have a firm grasp of using number bonds with addition and subtraction, they can be introduced to repeated addition and repeated subtraction using number bonds. The problem with repeated addition and subtraction is that they both take a long time. Guess what will save us some time? Multiplication and division! Same model, just a faster equation.

Then, when kids start working with fractions (a totally new concept), the number bond can be used to show that unit fractions are just parts of a bigger whole. This idea can be expanded as students work with adding and subtracting fractions or multiply fractions by whole numbers.

One model has taken our students through their entire elementary math experiences!

The other two models I like for this same purpose are tape diagrams and number lines. In fact, my absolute favorite model is the tape diagram. The number one reason I like the tape diagram is It is super fast to draw. I also like it because it looks like a fraction strip which is helpful as students are learning fractions as well.

I love these three models. I think that every teacher should have an understanding of the progression of how these models can be used from kindergarten to fifth grade. It would give kids a common "box" for their new math learnings.

If you are comfortable with these three models - that is wonderful! Keep using them to enhance your teaching.

If you are not comfortable with these models, or you are looking for something to put in your students' hands, then I have a freebie for you. You can get my Guide to Math Models by clicking the link at the bottom of the page.
