Why this works
On a cross-shaped net the four arms fold up into the four walls, the middle becomes the floor and the tail flips over to become the lid. Faces two steps apart in a straight line end up facing each other: middle↔tail, and the two arms across from each other. Faces that touch in the net can never be opposite - they share a hinge, so they meet at a corner.
Helping a child through Cube Net Folder
It runs in 2 steps
- 1. Fold it. Drag the fold track all the way across - watch the six faces close into a cube.
- 2. Opposite faces. Now the real question: which face ends up OPPOSITE the moon?
Hints, least revealing first
- Drag the coral knob slowly - the flaps swing up one at a time.
- Scrub back and forth. Watch where the moon flap ends up, then look straight across the box.
- On a cross net, two faces are opposite when there is exactly one face between them in a straight line. The moon and the heart are two apart down the upright.
When they finish it: “Boxed it!”
What usually goes wrong here
- Treats faces separated on the flat net as necessarily opposite.
This is the wrong answer 11+ papers are built to offer, so it is worth watching for directly: a child who does this will look confident and still lose the mark. If it keeps happening on track opposite cube faces, the fix is the misunderstanding rather than more questions.
2 11+ skills this exercise practises
Each of these has its own page, with a worked example on it. 1 of the 2 names the mistake that skill attracts.
- Track cube faces from a netDetermine an opposite or adjacent face after folding a cube net.
- Track opposite cube facesDetermine which marked face becomes opposite after folding.
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.
Embed this exercise
Paste this into your own page and the exercise runs there, playable, for your readers or your students. It is 900 pixels tall by default and as wide as the column you put it in; change the height if your layout wants a different one.
The embedded copy has no header, no footer and no sign-up prompt. It records nothing about the child using it, on your page just as on ours.
