How to use it
- Choose how many equal parts each circle is cut into.
- Tap a piece to shade up to it. Tap the last shaded piece to take one back.
- Read the fraction under each circle, which is more, and the sum with a common denominator.
- Press F for the projector, or Print to print what is on screen.
Ideas for class
- Shade 1/2 and 2/4 on two circles and ask why they look the same.
- Compare 3/8 and 2/3: which circle has more shaded? Then check with the words on the right.
- Add 1/3 and 1/6. Ask what the circle must be cut into so both fractions can be counted the same way.
- Shade three circles to show 5/4 and talk about when a fraction is more than one whole.
- Let a student come up and shade a fraction you say out loud, then have the class say it back.
- Use unit fractions only (one piece of each) and put them in order from biggest to smallest.

Which denominators can I use?
2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12. Those are the ones children meet from grades 1 to 6.
How does it add fractions with different parts?
It rewrites both over the same denominator first and shows that line, then adds and simplifies. Whole circles are shown as a mixed number.
