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.

Folding a net into a cube

Follow the dot face as this net folds up, and see where it ends up looking.

  1. the triangle face
  2. the crescent face
  3. the hexagon face
  4. the diamond face

Answer: the crescent face

How you get there

The crescent is not two steps along a straight line from the dot, 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 hexagon shares a hinge with the dot, so it folds up to touch it instead.

Why the other answers tempt

The hexagon face touches the dot once folded, so it can never be opposite it.

If they are stuck, say this

There is no straight run of three faces through the dot 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.

How each of these 2 exercises teaches it

Cube Net Folder

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

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.

Dice Partner

On every ordinary dice, the numbers on opposite faces add up to 7. Which number is hiding on the face opposite the 3?

A standard dice is built so that every pair of opposite faces adds to 7. That gives exactly three pairs: 1 with 6, 2 with 5, and 3 with 4. So the face opposite the 3 must be 4, because 3 plus 4 is 7. The strategy that saves you in the exam is to learn those three pairs by heart and then subtract: opposite face equals 7 minus the face you can see. It also lets you check a dice question quickly, because any two numbers shown next to each other on the same dice can never be a pair that adds to 7.

What to say if they get stuck

  1. You can see 1, 3 and 5. The three numbers you cannot see are on the opposite faces.
  2. Opposite faces always pair up to make 7. Write the three pairs out: 1 and ?, 2 and ?, 3 and ?
  3. You need the number that goes with 3 to make 7. What do you add to 3 to reach 7?

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.

Where track opposite cube faces sits in the 11+

The 11+ does not test these skills in isolation, and practising one in the wrong order wastes the practice. These are the skills the curriculum map connects this one to.

How track opposite cube faces 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 which marked face becomes opposite after folding, and it stops where one cube net and one target face.
