Sometimes colour theory can be such a task. And Class teachers are soon expecting Christmasy or wintery stuff for the walls - too early! So I devised a colour wheel with a snow flake design.
The class were given a folded 1/6 of a circle (yes more maths), and cut a simple snowflake segment. this was used as a template to draw a complete snowflake. (The children thought that they could reuse the template to make reindeer antlers.)
Primary colours are added then a secondary colour placed correctly, finally further variations of those colours, added in the negative spaces. i.e. yellow/green and blue/green.
A little bit of cutting round the edge emphasises the pattern.
Even the messy ones look great!
