This week, Jonathan will begin learning to use different strategies to add 3 numbers. Today, he was instructed to look for two numbers to add 1st, using a familiar strategy such as the 10-frame from his math tool kit and to then add the 3rd number. This should facilitate Jonathan's ability to think about number relationships. Jonathan used his preferred strategy to add 3 numbers solving problems in his Ready Classroom Mathematics book, and he demonstrated his ability to solve word problems calling for him to add add 3 whole numbers whose sum was less than or equal to 20.
