Math Mountains

We have been doing a lot of exploring with addition and subtraction equations. What we know and what we need to work on. 

A tool that has been a helpful resource this week have been Math Mountain Cards. These show a total (in all) at the top and two addends (partners) at the bottom. These give a visual representation of a total breaking apart into smaller numbers (addends). 

Math Mountains helps with:

Addition: Having two addends at the bottom to add together making a top total

Subtraction: Having a top total and needing to find an unknown addend

Students have learned to write addition and subtraction fact family equations that they can make from a variety of mountain cards.
