Production on set of our Math Movie Network has kicked into gear. Students have been hard at work preparing for our first video shoot by learning how to add, subtract, and multiply decimals.
We learned that when adding or subtracting decimals, the decimal points always need to line up. When we multiply decimals, the decimal points don’t need to line up.
