The Math Is Visual integer operation series continues with integer multiplication. The rules for multiplying positive and negative numbers are thought of as nothing more than a memory trick for many. Let's uncover one approach to viewing integer multiplication from the perspective of "groups of" for multiplication and "opposites" using colour for the positive and negative values.

Another math is visual prompt to help students intuitively understand subtraction of negative values. In this video, students will see two examples and then try to apply their understanding to a third scenario. We are slowly introducing symbolic notation here as well.

In my previous post, we looked at adding and subtracting integers by implicitly introducing the idea of the Zero Principle through the use of squares on the screen. While some might interpret the black squares to represent positive values and red to represent negative, the choice is really up to the viewer. 

This post introduces the red dots first. Under the assumption that many will believe the red to be negative, this post is intended to help students realize that order doesn't matter; positive or negative.

Watch the last of the integer addition and subtraction series which began first by using only square tiles and colour, then using number lines and colour and finally by introducing the symbolic notation for positive and negative values.

In the second last video of the integer addition and subtraction series, we use visual tiles to represent positive and negative integers and slowly introduce the symbolic notation traditionally used for adding and subtracting integers. This is a silent solution video from Math Is Visual. Get all of the resources here: http://mathisvisual.com/integer-addition-symbolic/

In the Gummy Worms Sequel, I put all the gummy worms back in the jar and then remove some.

The question is: "how many gummy worms are left in the jar?

In the previous video (Act 1) of the Gummy Worms 3 Act Math Task, students noticed and wondered. The question we landed on was "how many gummy worms are in the jar?"

After making predictions and sharing with the class, they can now see how close they were!

Act 1 of the Gummy Worms 3 Act Math Task shared on my website Tap Into Teen Minds.

What do you notice? What do you wonder?

In this video, viewers are given a second challenge where they are given 5 red squares and they must subtract 6 black squares. See the resources here: http://mathisvisual.com/integer-subtraction-number-lines/
