Have you noticed that triangles are used in manmade structures? Perhaps there is a good reason for this? 'Test a Triangle' and see how rigid triangles are.
Can you describe a piece of paper clearly enough for your partner to know which piece it is?
What do these two triangles have in common? How are they related?
Ideas for practical ways of representing data such as Venn and Carroll diagrams.
This practical problem challenges you to create shapes and patterns with two different types of triangle. You could even try overlapping them.
Follow the diagrams to make this patchwork piece, based on an octagon in a square.
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?
Kaia is sure that her father has worn a particular tie twice a week in at least five of the last ten weeks, but her father disagrees. Who do you think is right?
Can you see which tile is the odd one out in this design? Using the basic tile, can you make a repeating pattern to decorate our wall?
Can you make the most extraordinary, the most amazing, the most unusual patterns/designs from these triangles which are made in a special way?
Use the lines on this figure to show how the square can be divided into 2 halves, 3 thirds, 6 sixths and 9 ninths.
Follow these instructions to make a five-pointed snowflake from a square of paper.
Use the three triangles to fill these outline shapes. Perhaps you can create some of your own shapes for a friend to fill?
We can cut a small triangle off the corner of a square and then fit the two pieces together. Can you work out how these shapes are made from the two pieces?
Paint a stripe on a cardboard roll. Can you predict what will happen when it is rolled across a sheet of paper?
