The Opposite of the Opposite

It's been a while since I've updated but currently my class is working with negative and positive integers/rational numbers.  In order to get my students to understand the concept that two negative signs create a positive sign (i.e. -(-3) = +3), I've decided to crank out the number line/coordinate plane! Unfortunately the coordinate plane I had last year got lost during the transition in moving from upstairs to downstairs, so I have to create a new one.

Below is a video of them ordering themselves from least to greatest after they understood that the opposite of an opposite is the equal to the number itself.

Unlike last year, many students have expressed interest in sharing their opinions on what math is like for them this year compared to last year. Now that there's a bit more time because of the holiday, I'll try to get to it by Wednesday!
