Here is a version of the game 'Happy Families' for you to make and play.
Make your own double-sided magic square. But can you complete both sides once you've made the pieces?
Use the tangram pieces to make our pictures, or to design some of your own!
Can you make the birds from the egg tangram?
Investigate the smallest number of moves it takes to turn these mats upside-down if you can only turn exactly three at a time.
A game in which players take it in turns to choose a number. Can you block your opponent?
Take a rectangle of paper and fold it in half, and half again, to make four smaller rectangles. How many different ways can you fold it up?
A game to make and play based on the number line.
Can you work out what shape is made by folding in this way? Why not create some patterns using this shape but in different sizes?
Can you predict when you'll be clapping and when you'll be clicking if you start this rhythm? How about when a friend begins a new rhythm at the same time?
If you split the square into these two pieces, it is possible to fit the pieces together again to make a new shape. How many new shapes can you make?
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?
Use the lines on this figure to show how the square can be divided into 2 halves, 3 thirds, 6 sixths and 9 ninths.
Paint a stripe on a cardboard roll. Can you predict what will happen when it is rolled across a sheet of paper?
What is the greatest number of squares you can make by overlapping three squares?
Have a look at what happens when you pull a reef knot and a granny knot tight. Which do you think is best for securing things together? Why?
Factors and Multiples game for an adult and child. How can you make sure you win this game?
These are pictures of the sea defences at New Brighton. Can you work out what a basic shape might be in both images of the sea wall and work out a way they might fit together?
Make a flower design using the same shape made out of different sizes of paper.
Can you work out what shape is made when this piece of paper is folded up using the crease pattern shown?
This problem invites you to build 3D shapes using two different triangles. Can you make the shapes from the pictures?
Have a go at making a few of these shapes from paper in different sizes. What patterns can you create?
This problem focuses on Dienes' Logiblocs. What is the same and what is different about these pairs of shapes? Can you describe the shapes in the picture?
Exploring and predicting folding, cutting and punching holes and making spirals.
In how many ways can you fit two of these yellow triangles together? Can you predict the number of ways two blue triangles can be fitted together?
How can you put five cereal packets together to make different shapes if you must put them face-to-face?
Move four sticks so there are exactly four triangles.
Surprise your friends with this magic square trick.
Make a cube out of straws and have a go at this practical challenge.
Use the three triangles to fill these outline shapes. Perhaps you can create some of your own shapes for a friend to fill?
Are all the possible combinations of two shapes included in this set of 27 cards? How do you know?
Take 5 cubes of one colour and 2 of another colour. How many different ways can you join them if the 5 must touch the table and the 2 must not touch the table?
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?
Arrange 9 red cubes, 9 blue cubes and 9 yellow cubes into a large 3 by 3 cube. No row or column of cubes must contain two cubes of the same colour.
Using different numbers of sticks, how many different triangles are you able to make? Can you make any rules about the numbers of sticks that make the most triangles?
Can you cut up a square in the way shown and make the pieces into a triangle?
Here are some ideas to try in the classroom for using counters to investigate number patterns.
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.
If you have ten counters numbered 1 to 10, how many can you put into pairs that add to 10? Which ones do you have to leave out? Why?
How do you know if your set of dominoes is complete?
Looking at the picture of this Jomista Mat, can you decribe what you see? Why not try and make one yourself?
These practical challenges are all about making a 'tray' and covering it with paper.
Have you ever tried tessellating capital letters? Have a look at these examples and then try some for yourself.
These squares have been made from Cuisenaire rods. Can you describe the pattern? What would the next square look like?
Take a counter and surround it by a ring of other counters that MUST touch two others. How many are needed?
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?
How many models can you find which obey these rules?
What is the smallest cuboid that you can put in this box so that you cannot fit another that's the same into it?
Can you describe a piece of paper clearly enough for your partner to know which piece it is?
Can you split each of the shapes below in half so that the two parts are exactly the same?
