Inverses for Elementary Kids | Children - Doing and Undoing in Math

This film introduces elementary kids / children to the concept of inverses. In life and math, we are always doing and undoing things; we zip and unzip, we pack and unpack. Each of these operations is the inverse of the other. Doing inverses makes things the way they were before anything was done. The idea of an inverse is very useful in math. Subtracting a number is the inverse of adding the same number, and adding a number is the inverse of subtracting the same number. This is a great film for elementary kids and children that clearly explains inverses in a language that is easy to understand.
