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

This interactivity allows you to sort logic blocks by dragging their images.

My cube has inky marks on each face. Can you find the route it has taken? What does each face look like?

Investigate the number of faces you can see when you arrange three cubes in different ways.

Here are four cubes joined together. How many other arrangements of four cubes can you find? Can you draw them on dotty paper?

Board Block game for two. Can you stop your partner from being able to make a shape on the board?

Players take it in turns to choose a dot on the grid. The winner is the first to have four dots that can be joined to form a square.

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

Where can you put the mirror across the square so that you can still "see" the whole square? How many different positions are possible?

Use the isometric grid paper to find the different polygons.

How can you arrange the 5 cubes so that you need the smallest number of Brush Loads of paint to cover them? Try with other numbers of cubes as well.

This problem explores the shapes and symmetries in some national flags.

Here are the six faces of a cube - in no particular order. Here are three views of the cube. Can you deduce where the faces are in relation to each other and record them on the net of this cube?

Here are some pictures of 3D shapes made from cubes. Can you make these shapes yourself?

The ancient Egyptians were said to make right-angled triangles using a rope with twelve equal sections divided by knots. What other triangles could you make if you had a rope like this?

This practical problem challenges you to make quadrilaterals with a loop of string. You'll need some friends to help!

You have been given three shapes made out of sponge: a sphere, a cylinder and a cone. Your challenge is to find out how to cut them to make different shapes for printing.

Each of the nets of nine solid shapes has been cut into two pieces. Can you see which pieces go together?

Imagine a pyramid which is built in square layers of small cubes. If we number the cubes from the top, starting with 1, can you picture which cubes are directly below this first cube?

What is the greatest number of counters you can place on the grid below without four of them lying at the corners of a square?

Let's say you can only use two different lengths - 2 units and 4 units. Using just these 2 lengths as the edges how many different cuboids can you make?

Can you dissect an equilateral triangle into 6 smaller ones? What number of smaller equilateral triangles is it NOT possible to dissect a larger equilateral triangle into?

How many different triangles can you make on a circular pegboard that has nine pegs?

How many DIFFERENT quadrilaterals can be made by joining the dots on the 8-point circle?

Choose the size of your pegboard and the shapes you can make. Can you work out the strategies needed to block your opponent?

Can you make a spiral for yourself? Explore some different ways to create your own spiral pattern and explore differences between different spirals.

This task develops spatial reasoning skills. By framing and asking questions a member of the team has to find out what mathematical object they have chosen.

This task requires learners to explain and help others, asking and answering questions.
