In a previous post I mentioned the make a ten strategy. This week we dove into the concept and looked at the foundation and number sense we need in order to use this strategy efficiently.
At the beginning of the week, we started exploring this strategy using cubes. I put a pile of cubes in front of small groups of students and asked them how many cubes they had. Immediately each group started forming "10 sticks." This is something they are familiar with from our daily math routine we complete after recess.
Each group had some "tens" and "ones" left over. Counting by tens until they reached the ones, most groups had between 90-110 cubes. Then we charted how many tens each group had and how many ones, as well as the number they had all together.
You can do this at home! Most snacks have many pieces. Fruits snacks and Goldfish crackers are examples. Ask your child how many they have of their snack. Then ask if there's a different way to count it (1's, 2's, 5's, or 10's). This will help them become flexible thinkers and prepare them for addition and subtraction of larger numbers.
