How to use the Fraction Tools
- Choose a view. Pick Fraction wall, Circles, Compare or Equivalent at the top, or press 1 to 4.
- Shade and explore. Click pieces on the wall or slices of a circle to shade them; the shaded amount appears beside them. In Compare and Equivalent, use the + and − buttons to set each numerator and denominator.
- Change the labels. In Settings, show each piece as a fraction, a decimal or a percent — or no label at all. Press L to switch quickly.
- Quiz the class. Press Space to hide the answers, ask the question, then press it again to reveal them.
Classroom ideas
- Which is bigger? In Compare, set up 3/4 and 4/5, hide the answers, and let pupils vote with thumbs up or down before you reveal the sign and the common denominator.
- Equivalent hunt: choose 2/3 in the Equivalent view and ask pairs to name every row the guide line lands on exactly — then check together.
- Pizza problems: in Circles, show two wholes cut into quarters and shade 5 slices to meet improper fractions and mixed numbers (5/4 = 1 1/4).
- Fractions, decimals, percents: switch the wall’s labels from fractions to decimals to percents and talk about why 1/4, 0.25 and 25% sit in the same place.
- Use it on the Classroom Board next to the number line set to quarters or eighths, so fractions appear as both lengths and points.

Frequently asked questions
Which denominators can I use?
Every denominator from 1 (a whole) to 12. Choose which rows the fraction wall shows in Settings: all twelve, the common ones, or just halves, quarters and eighths.
How does Compare work out the answer?
It rewrites both fractions over their least common denominator — for 2/3 and 3/4 that is twelfths, 8/12 and 9/12 — then compares the numerators. The bars are drawn one above the other at the same length, so the difference is easy to see.
Why are some rows faded in the Equivalent view?
A faded row has no piece edge exactly on the chosen fraction, so it has no equivalent fraction with that denominator. For 1/2 the halves, quarters, sixths, eighths, tenths and twelfths light up; the thirds do not.
Can I show decimals or percents instead?
Yes. In Settings, set Labels to Decimals or Percents. Repeating decimals such as 1/3 are rounded and marked with ≈.
Can pupils use it on an interactive whiteboard?
Yes. Pieces and slices respond to a tap, and every button is large enough for a finger.
