Activity Instructions

Create index cards with addition and subtraction problems using fractions with the same denominator (e.g. 1/5 + 4/5; 6/7 – 2/7). Pick a card and use the mat to solve the problem. Stand on the first fraction. For addition, you’ll walk forwards. For subtraction, you’ll walk backwards. Count each fraction block as you move. The number you end on is the answer to the problem.

Sample Questions:
What is â…™ + â…š?
What is ⅜ + ⅜?
What is 2/7 + 4/7?
What is 2/10 + 5/10?
What is ¼ + 2/4?
