Why this works
Cutting every piece again multiplies how many pieces there are AND how many you shade, so the amount of chocolate never changes. , and are one single quantity wearing three different numbers. That is what "equivalent" means: different names, identical amount.
Helping a child through Fraction Slicer
It runs in 2 steps
- 1. Slice & shade. Slice the bar into equal pieces, then tap pieces to shade three quarters of it.
- 2. The overlay. Lower the teal bar onto yours. Where does each shading stop?
Hints, least revealing first
- Drag the CUTS slider until the bar falls into 4 equal pieces.
- The bottom number says how many pieces the WHOLE is cut into. The top number says how many of them you take.
- In step 2, lower the teal bar straight down onto yours and watch where each shading STOPS.
When they finish it: “Perfectly sliced!”

You can reuse this. Here is exactly how far that goes
Tutors, teachers and editors keep asking, so this is the answer in writing rather than by email. You do not need to ask permission, and you do not need to tell us.
- Embed it
- Put the exercise inside your own page with the code above. It stays playable, and it keeps working when we improve the engine behind it.
- Print it
- Print the page, or print the exercise off the screen, and hand out the copies. No limit on how many.
- Use it in class
- One child or a full set, in a school, in a tutoring session, in a homework club, or at the kitchen table.
- Put it in something you charge for
- A paid course, a paid tutoring session, a paid workbook, a members-only site. You owe us no fee and you do not need to ask.
- Reuse it in your own writing
- Quote it, rewrite it, translate it, cut it up, or build something different on top of it. Treat the wording, the worked examples and the question ideas as yours to work with.
The one thing we ask is a link back to the page you took it from, so a reader can find the live, playable version and the rest of the 11+ skills next to it. That is a request, not a condition: nothing above depends on it.
This covers the interactive exercises and the teaching notes on these 11+ pages. It does not cover the Trace Learn name or logo, and it does not let you present your version as something Trace Learn published.
