How many different triangles can you draw on the dotty grid which each have one dot in the middle?
This challenge involves eight three-cube models made from interlocking cubes. Investigate different ways of putting the models together then compare your constructions.
How many different ways can you find to join three equilateral triangles together? Can you convince us that you have found them all?
This challenge invites you to create your own picture using just straight lines. Can you identify shapes with the same number of sides and decorate them in the same way?
This practical activity challenges you to create symmetrical designs by cutting a square into strips.
What does the overlap of these two shapes look like? Try picturing it in your head and then use the interactivity to test your prediction.
A hundred square has been printed on both sides of a piece of paper. What is on the back of 100? 58? 23? 19?
The computer has made a rectangle and will tell you the number of spots it uses in total. Can you find out where the rectangle is?
Vincent and Tara are making triangles with the class construction set. They have a pile of strips of different lengths. How many different triangles can they make?
In this town, houses are built with one room for each person. There are some families of seven people living in the town. In how many different ways can they build their houses?
Sara and Will were sorting some pictures of shapes on cards. "I'll collect the circles," said Sara. "I'll take the red ones," answered Will. Can you see any cards they would both want?
Create a pattern on the left-hand grid. How could you extend your pattern on the right-hand grid?
My cube has inky marks on each face. Can you find the route it has taken? What does each face look like?
How many possible necklaces can you find? And how do you know you've found them all?
Investigate the number of faces you can see when you arrange three cubes in different ways.
In how many different ways can you break up a stick of 7 interlocking cubes? Now try with a stick of 8 cubes and a stick of 6 cubes.
Can you each work out what shape you have part of on your card? What will the rest of it look like?
Explore ways of colouring this set of triangles. Can you make symmetrical patterns?
This ladybird is taking a walk round a triangle. Can you see how much he has turned when he gets back to where he started?
These caterpillars have 16 parts. What different shapes do they make if each part lies in the small squares of a 4 by 4 square?
This problem is intended to get children to look really hard at something they will see many times in the next few months.
The red ring is inside the blue ring in this picture. Can you rearrange the rings in different ways? Perhaps you can overlap them or put one outside another?
What patterns can you make with a set of dominoes?
Are these statements relating to calculation and properties of shapes always true, sometimes true or never true?
Arrange the shapes in a line so that you change either colour or shape in the next piece along. Can you find several ways to start with a blue triangle and end with a red circle?
These pictures were made by starting with a square, finding the half-way point on each side and joining those points up. You could investigate your own starting shape.
Shapes are added to other shapes. Can you see what is happening? What is the rule?
