What do you think is the same about these two Logic Blocks? What others do you think go with them in the set?
This interactivity allows you to sort logic blocks by dragging their images.
Can you each work out what shape you have part of on your card? What will the rest of it look like?
This activity challenges you to make collections of shapes. Can you give your collection a name?
Are all the possible combinations of two shapes included in this set of 27 cards? How do you know?
Can you spot circles, spirals and other types of curves in these photos?
Look at the mathematics that is all around us - this circular window is a wonderful example.
What shape is the overlap when you slide one of these shapes half way across another? Can you picture it in your head? Use the interactivity to check your visualisation.
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?
If these balls are put on a line with each ball touching the one in front and the one behind, which arrangement makes the shortest line of balls?
This problem is intended to get children to look really hard at something they will see many times in the next few months.
Can you reproduce the Yin Yang symbol using a pair of compasses?
What shaped overlaps can you make with two circles which are the same size? What shapes are 'left over'? What shapes can you make when the circles are different sizes?
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?
A cheap and simple toy with lots of mathematics. Can you interpret the images that are produced? Can you predict the pattern that will be produced using different wheels?
This article for pupils gives some examples of how circles have featured in people's lives for centuries.
Read all about the number pi and the mathematicians who have tried to find out its value as accurately as possible.
Learn how to draw circles using Logo. Wait a minute! Are they really circles? If not what are they?
