Mastering Two-Step Problem Solving with Counters

Mr. Matt Blog introduces a lesson on solving two-step problems using the 'act it out' strategy. He demonstrates this with two examples: finding the price of a magazine and determining the number of pins in each pack. The lesson involves using addition, subtraction, and division to solve these problems. Mr. Matt explains the necessity of using multiple operations and checks the solutions by working backward.

What is the main strategy discussed in the video for solving two-step problems?

• Draw a diagram

• Act it out

• Use a formula

• Guess and check
