What will Ben and his mom find on the next floor?
Math Connections:
Subtraction
Activities to Do Together:
 Talk about subtraction. Talk about a time each of you have used subtraction.
 While picking up toys, practice subtraction. Count how many toys there are to put away. Ask your child to figure out how many toys will be left when two toys are put back where they belong. As more and more toys are picked up, keep subtracting to see how many toys remain.

Practice subtraction the next time you use an elevator together. Tell them how many floors you want to travel down and have them figure out which button they need to press.
