Math foundations with positive and negative numbers and fractions.

I created a series of lessons focused on math foundations that emphasize different thinking styles.

addition and subtraction with the number line

Adding and Subtracting with the Number Line

For most students, the number line makes sense.

Addition and Subtraction with Patterns

Adding with Patterns

Not everyone thinks in number lines. Some people think in patterns.

Subtraction with Rewriting

Any subtraction problem can be made into an addition problem.

Subtraction with Flipping

You can also think of subtraction as flipping.

Multiplication

Go backwards...it's fine

Like addition, order doesn't matter when you multiply

Break it....it's fine

While most students are taught a highly procedural method to multiply multiple digits, many students break up numbers into little pieces. Either way works.

Division

Different ways to Divide

Different countries teach division differently. Some teach it as a series of multiplaction.

Chunking - a way to divide

This is another way to look at division.

Fractions - Introduction

Solving Sharing Problems 1

Let's do something with fractions.

Food on Top, People on the Bottom.

Solving Sharing Problems 2

We can put other stuff for sharing on top, and other things that share on the bottom.
