These activities are part of our Primary collections, which are problems grouped by topic.

Triple Cubes

Age 5 to 11
Challenge Level Yellow star

This challenge involves eight three-cube models made from interlocking cubes. Investigate different ways of putting the models together then compare your constructions.

A Cartesian Puzzle

Age 7 to 11
Challenge Level Yellow star

Find the missing coordinates which will form these eight quadrilaterals. These coordinates themselves will then form a shape with rotational and line symmetry.

Transformations on a Pegboard

Age 7 to 11
Challenge Level Yellow star

How would you move the bands on the pegboard to alter these shapes?

Coordinate Challenge

Age 7 to 11
Challenge Level Yellow star

Use the clues about the symmetrical properties of these letters to place them on the grid.

Treasure Hunt

Age 7 to 14
Challenge Level Yellow star

Can you find a reliable strategy for choosing coordinates that will locate the treasure in the minimum number of guesses?

Eight Hidden Squares

Age 7 to 14
Challenge Level Yellow starYellow star

On the graph there are 28 marked points. These points all mark the vertices (corners) of eight hidden squares. Can you find the eight hidden squares?

Ten Hidden Squares

Age 7 to 14
Challenge Level Yellow starYellow starYellow star

These points all mark the vertices (corners) of ten hidden squares. Can you find the 10 hidden squares?
