We start by playing a couple of rounds of 'Roll A Miro' - there are a few versions of this game out there and mine if definitely not the first!
This is the link to my version - feel free to use it!
Roll A Miro Game
This is a great way to introduce the work of Miro and the types of lines, patterns and symbols that he uses.
The students then create their own Miro inspired 'creature' - I ask them to draw nice and large onto A3 paper and to include some of the shapes into the background. They then go over their pencil lines with a black wax crayon.
