Solving Two-Step Addition and Subtraction Problems

This video tutorial teaches how to solve two-step addition and subtraction problems using a number line. It begins with a numerical example, 18 - 4 + 6, demonstrating the process of breaking down the problem into two steps. The tutorial then applies the same method to word problems, such as calculating the total number of stickers Austin has after losing and gaining some, and determining the total number of balloons Tina and Jack have for a party. The video emphasizes the importance of understanding each step and using a number line to visualize the operations.

What is the first step in solving 18 minus 4 plus 6?

• Add 6 to 4

• Subtract 4 from 18
