How to Use a Number Line for Addition

Using a number line to solve addition problems can make it easier to grasp the concept of moving from one number to another. Here’s a simple guide to help you get started:

  1. Start with Your First Number: Place the first number on the number line. This is where you’ll begin.
  2. Add the Second Number: Move to the right on the number line by the value of the second number.
  3. Find the Sum: The point you land on is your answer.

For example, if you’re solving 1 + 2, start at 7 on the number line, and move 2steps to the right. You’ll land at 3, which is the sum of 1 and 2.
