A worked example

One question of the kind this skill is tested with, worked all the way through: the reasoning, and what the wrong answers are there to catch.

Lid and base of a folded cube

Watch the star face rise to become the lid of the cube.

  1. the two dots face
  2. the circle face
  3. the star face
  4. the dot face

Answer: the circle face

How you get there

A cube has three pairs of opposite faces, so fixing the lid fixes the base too. The circle is not two steps along a straight line from the star, so the counting trick says nothing here - but folding the net closes the two of them onto opposite sides of the cube all the same. The two-dots shares a hinge with the star, so it folds up to touch it instead.

Why the other answers tempt

The two-dots face becomes a wall of the cube, not the base.

If they are stuck, say this

There is no straight run of three faces through the star here, so the counting trick will not help. Fold the net up one flap at a time and watch which face ends up out of sight behind it.

What this exercise is doing

Cube Net Folder

Drag the fold track and watch the flat net close into a cube.

This engine’s own main skill is Nets & Solids. It practises track cube faces from a net alongside it.

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.

  1. Step 1. Fold it. Drag the fold track all the way across - watch the six faces close into a cube.
  2. Step 2. Opposite faces. Now the real question: which face ends up OPPOSITE the moon?

What to say if they get stuck

  1. Drag the coral knob slowly - the flaps swing up one at a time.
  2. Scrub back and forth. Watch where the moon flap ends up, then look straight across the box.
  3. 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.

How track cube faces from a net differs from the skills beside it

The same exercise practises one other skill, and telling them apart is often the difficulty rather than the exercise itself. On this page the skill is: determine an opposite or adjacent face after folding a cube net, and it stops where one fixed net and one face relation.
