Complete the squares - but be warned some are trickier than they
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?

the 3 pieces to make a large triangle, a parallelogram and the
These pictures show squares split into halves. Can you find other ways?
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?
What is the greatest number of squares you can make by overlapping
A group activity using visualisation of squares and triangles.
This interactivity allows you to sort logic blocks by dragging their images.

set of 27 cards? How do you know?

Have a good look at these images. Can you describe what is happening? There are plenty more images like this on NRICH's Exploring Squares CD.
This collection of resources is designed to enable children to
explore concepts and ideas associated with squares.
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?
Investigate how this pattern of squares continues. You could
measure lengths, areas and angles.
Investigate all the different squares you can make on this 5 by 5
grid by making your starting side go from the bottom left hand
point. Can you find out the areas of all these squares?
How many ways can you find of tiling the square patio, using square
tiles of different sizes?

This practical challenge invites you to investigate the different
squares you can make on a square geoboard or pegboard.
What is the smallest number of tiles needed to tile this patio? Can
you investigate patios of different sizes?
Start with a large square, join the midpoints of its sides, you'll see four right angled triangles. Remove these triangles, a second square is left. Repeat the operation. What happens?
This problem challenges you to work out what fraction of the whole area of these pictures is taken up by various shapes.
Players take it in turns to choose a dot on the grid. The winner is the first to have four dots that can be joined to form a square.
This activity investigates how you might make squares and pentominoes from Polydron.
What can you see? What do you notice? What questions can you ask?
This article for teachers suggests activities based on pegboards, from pattern generation to finding all possible triangles, for example.
Can you use LOGO to create this star pattern made from squares.
Only basic LOGO knowledge needed.
Nine squares with side lengths 1, 4, 7, 8, 9, 10, 14, 15, and 18 cm can be fitted together to form a rectangle. What are the dimensions of the rectangle?
