Teachers, save “Compensation Strategy: Addition” to assign it to your class.

One number is rounded up to the next 10, the addition is carried out and then the answer is adjusted to compensate for the original change. Task: Demonstrate how you can use the compensation strategy to solve an addition problem of your choice. Explain what you are doing as you go.
