Creating designs with squares - using the REPEAT command in LOGO.
This requires some careful thought on angles
This LOGO Challenge emphasises the idea of breaking down a problem
into smaller manageable parts. Working on squares and angles.
Using LOGO, can you construct elegant procedures that will draw
this family of 'floor coverings'?
Can you use LOGO to create a systematic reproduction of a basic
design? An introduction to variables in a familiar setting.
Look at how the pattern is built up - in that way you will know how
to break the final pattern down into more manageable pieces.
Can you use LOGO to create this star pattern made from squares.
Only basic LOGO knowledge needed.
Just four procedures were used to produce a design. How was it
done? Can you be systematic and elegant so that someone can follow
This collection of resources is designed to enable children to
explore concepts and ideas associated with squares.
A Short introduction to using Logo. This is the first in a twelve part series.

squares you can make on a square geoboard or pegboard.
How many centimetres of rope will I need to make another mat just
like the one I have here?
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.
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?
This interactivity allows you to sort logic blocks by dragging their images.
On the graph there are 28 marked points. These points all mark the
vertices (corners) of eight hidden squares. Can you find the eight
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.
ABCD is a regular tetrahedron and the points P, Q, R and S are the midpoints of the edges AB, BD, CD and CA. Prove that PQRS is a square.
A tilted square is a square with no horizontal sides. Can you
devise a general instruction for the construction of a square when
you are given just one of its sides?
Investigate how this pattern of squares continues. You could
measure lengths, areas and angles.
Can you recreate squares and rhombuses if you are only given a side
or a diagonal?
Here are four tiles. They can be arranged in a 2 by 2 square so
that this large square has a green edge. If the tiles are moved
around, we can make a 2 by 2 square with a blue edge... Now try. . . .
What can you see? What do you notice? What questions can you ask?
It is possible to dissect any square into smaller squares. What is
the minimum number of squares a 13 by 13 square can be dissected
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?
The whole set of tiles is used to make a square. This has a green and blue border. There are no green or blue tiles anywhere in the square except on this border. How many tiles are there in the set?

contains 20 squares. What size rectangle(s) contain(s) exactly 100
squares? Can you find them all?

small. He took up the tiles, bought 100 more and used them to pave
another square courtyard. How many tiles did he use altogether?
