Addition Facts to 20 Using a Number Line

One of the key math skills for grade school students is to add numbers. They need to have a good grasp of their addition facts. A very helpful tool when adding is a number line. A number line is a great model to use specially when adding. It visualises the movement of the numbers forwards or backwards. So, yes! It’s a great tool for subtraction too!

To use the number line for addition, you start with the bigger number. Mark the bigger number on the number line. Look at the smaller number. Make the number of jumps on the number line. The sum is the number where you stopped. 

Here’s a worksheet to practice adding on a number line. This worksheet reviews addition facts to 20.  It is best used when printed out. Place it in a dry-erase pocket so you can reuse the number line on top.
