This interactivity allows you to sort logic blocks by dragging their images.
What do you think is the same about these two Logic Blocks? What
others do you think go with them in the set?
This activity challenges you to make collections of shapes. Can you
give your collection a name?
Look at the mathematics that is all around us - this circular
window is a wonderful example.
Can you spot circles, spirals and other types of curves in these photos?
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?
Are all the possible combinations of two shapes included in this
set of 27 cards? How do you know?
Can you each work out what shape you have part of on your card?
What will the rest of it look like?
Can you reproduce the Yin Yang symbol using a pair of compasses?
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 problem is intended to get children to look really hard at something they will see many times in the next few months.
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.
This article for pupils gives some examples of how circles have featured in people's lives for centuries.
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?
Read all about the number pi and the mathematicians who have tried to find out its value as accurately as possible.
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?
Learn how to draw circles using Logo. Wait a minute! Are they really circles? If not what are they?
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
A metal puzzle which led to some mathematical questions.
