Four triangles puzzle
Cut four triangles from a square as shown in the picture. How many different shapes can you make by fitting the four triangles back together?
Sorting logic blocks
This activity focuses on similarities and differences between shapes.
Seeing squares
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.
Triple cubes
This challenge involves eight three-cube models made from interlocking cubes. Investigate different ways of putting the models together then compare your constructions.
The third dimension
Here are four cubes joined together. How many other arrangements of four cubes can you find? Can you draw them on dotty paper?
Shape draw
Use the information on these cards to draw the shape that is being described.
Nine-pin triangles
How many different triangles can you make on a circular pegboard that has nine pegs?
What shape?
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.
Let us reflect
Where can you put the mirror across the square so that you can still "see" the whole square? How many different positions are possible?
Counters in the middle
This task depends on groups working collaboratively, discussing and reasoning to agree a final product.
Guess what?
Seeing parallelograms
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 parallelogram.
Bracelets
Investigate the different shaped bracelets you could make from 18 different spherical beads. How do they compare if you use 24 beads?
A puzzling cube
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?
Square corners
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?
Building blocks
Diagonally square
Round a hexagon
This problem shows that the external angles of an irregular hexagon add to a circle.
Always, sometimes or never? Shape
Are these statements always true, sometimes true or never true?
Stick images
This task requires learners to explain and help others, asking and answering questions.
Name that triangle!
Can you sketch triangles that fit in the cells in this grid? Which ones are impossible? How do you know?
National flags
How safe are you?
Six places to visit

Sponge sections
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.
Shapes on the playground
Quad match
A task which depends on members of the group noticing the needs of others and responding.
Stringy quads
This practical problem challenges you to make quadrilaterals with a loop of string. You'll need some friends to help!
Making cuboids
Seeing rhombuses
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 rhombus.
Cut nets
Each of the nets of nine solid shapes has been cut into two pieces. Can you see which pieces go together?
Egyptian rope
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?
Overlapping again
Arranging cubes
A task which depends on members of the group working collaboratively to reach a single goal.
Making rectangles
A task which depends on members of the group noticing the needs of others and responding.

For this task, you'll need an A4 sheet and two A5 transparent sheets. Decide on a way of arranging the A5 sheets on top of the A4 sheet and explore ...
Cut it out
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?
Quadrilaterals
How many DIFFERENT quadrilaterals can be made by joining the dots on the 8-point circle?
Board block challenge
Choose the size of your pegboard and the shapes you can make. Can you work out the strategies needed to block your opponent?
Triangles all around
Inky cube
This cube has ink on each face which leaves marks on paper as it is rolled. Can you work out what is on each face and the route it has taken?
Symmetry challenge
ReflectoR ! RotcelfeR
Can you place the blocks so that you see the reflection in the picture?
Olympic turns
This task looks at the different turns involved in different Olympic sports as a way of exploring the mathematics of turns and angles.
