Group art

You need:

1. MDF board one square meter
2. tempera paint
3. brushes
4. black marker

This is a group work for about 24 kids. Kids work in turn on it.
Buy a MDF board from one square meter. Choose another size if your class has more students, or if you want to make a rectangle instead of a square. Divide it in 25 squares from 20 centimeters (or less or more rectangles if you want to).
Every student gets one square to fill with simple forms. Colour them in blue and green (or other colours if these fit better in your classroom). You may have overlaps. Outline all figures with a black marker. Write the names of all artists in an empty square.
