This app explores adding proper fractions that may or may not start with common denominators using fraction circles.

- Create your fractions you want to add. You will get a message if your fractions are not proper, or if your common denominator is greater than 32.
- If you
*need*common denominators, click "Equivalent Fractions." Drag the slider until you find a common denominator that will create equivalent fractions. - Click "Combine Fractions" to add the two fraction circles.
- Write in your solution to see if you found the correct sum! You can provide either a mixed number or improper fraction for sums greater than 1.
