This activity is a great way for students practice adding and subtracting decimal numbers. I printed the activity on astrobright paper and laminated it. I put painters tape on a wall and put the numbers 0, 0.5, and 1 on the number line. The students picked an addition or subtraction card and once they solved it they needed to find the card with their answer and plot it on the number line. This is a great activity for adding and subtracting decimal numbers and plotting decimals on a number line.
