A Short introduction to using Logo. This is the first in a twelve part series.
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 a systematic reproduction of a basic
design? An introduction to variables in a familiar setting.
This LOGO Challenge emphasises the idea of breaking down a problem
into smaller manageable parts. Working on squares and angles.

This article for teachers suggests activities based on pegboards, from pattern generation to finding all possible triangles, for example.
What can you see? What do you notice? What questions can you ask?
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?
On the graph there are 28 marked points. These points all mark the
vertices (corners) of eight hidden squares. Can you find the eight
It's easy to work out the areas of most squares that we meet, but
what if they were tilted?
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 practical challenge invites you to investigate the different
squares you can make on a square geoboard or pegboard.
