Missing numbers!

We have used our rekenreks to help us find missing numbers in part-part-whole models. We know that if we need to find a missing whole, we use addition and that if we need to find a missing part, we use subtraction.

Addition! 

We are learning to add two 2-digit numbers in different ways. We used dienes to help us add the tens and ones to find the sum.
