# Number Lines: One and Two-Digit Addition

Good luck and have fun.

## Directions

You have probably seen number lines before. You start at one point and then count to the left or right. When you count, you hop from one point to the next. This activity gives you a number line to help you solve simple addition problems. Use the line to figure out your sum and then click the correct answer. After you click, you will see the correct sum and number line work.

You get a happy face for every correct answer and a sad face for every wrong answer. The quiz is over after ten (10) questions. Take the quiz again and again because all of the questions are random. You should get a new quiz every time. It's good practice to learn these basic arithmetic comparisons.
