Arithmetic Grade Two

Lesson Thirty-one: Adding Three Numbers

Adding Three Numbers

The order you add the numbers doesn't matter. Look at these examples:


	10 + 70 + 2 = 82

	20 + 60 + 2 = 82

	30 + 50 + 2 = 82

	40 + 40 + 2 = 82

	70 + 10 + 2 = 82

	60 + 20 + 2 = 82

NOTE: Make several addition problems with three digits similar to those presented in this lesson for the student to solve.
