Math: Operations and Algebraic Thinking 2. Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.
Teacher note: Start with 10 counters in a cup. Then, follow the script.
What’s Hiding?
I have some counters in my cup. I take out 3. 7 are left. How many counters were in my cup?
Write a number sentence to represent the problem. Use “c” to represent the missing counters.
