For the second week in a row, we are including a "What's Inside the Cup?" page in the homework packet.  When we play this game at school, we call this game "Bears in a Cave."  There's something fun about hiding our bear-shaped counters beneath a cup and hoping our friend will calculate the correct number.

Both versions of the game start with a total number.  In the next few weeks, we will be expanding our range to higher numbers.  For now, we have been working primarily in the 8-12 range.

Knowing the total number, one partner keeps some number of bears outside and hides the remaining bears beneath the cup, or cave.  The other partner has to figure out how many bears are hiding, based on knowing the total number and how many are outside. 

This is great practice for us in both addition and subtraction, and I encourage you to play at home.  All you need is a handful of buttons, coins, or other small objects and an opaque cup.  As you play, please ask your child to explain his/her thinking.  How do you know?
