Advanced Non-Verbal Reasoning: Counting Cubes in 3D Shapes
How many cubes are in this 3D stack, including the ones you can’t see? Ellie the elephant counts layer by layer from the bottom (6, then 3, then 1, making 10) and explains why every cube on top needs a cube underneath it. Then count a smaller stack of 5.

Which flat net folds into a cube? Bruno the bear watches a cross-shaped net fold up into a box and learns three rules: six squares, never more than four in a row, and no 2 by 2 block. Then choose which of two nets makes a cube.
1:38Non-Verbal Reasoning: Cubes, Dice and Opposite Faces
On a normal dice, opposite faces add up to 7: 1 and 6, 2 and 5, 3 and 4. Bruno the bear uses this to find the hidden bottom face when 3 is on top (4), and learns that opposite faces can never be seen at the same time. Then find the total of the three hidden faces yourself.
1:47Non-Verbal Reasoning: Paper Folding and Hole Punching
Rosie the rabbit folds a sheet of paper in half, punches one hole, and unfolds it. Every layer gets a hole, and the holes are mirror images across the fold line. Then work out what happens when the paper is folded twice into quarters before punching.
