Paint a white sheet of paper with liquid watercolour and a lot of water a plain background.

Drip some liquid water colour on the surface while it is still wet. Use more water if the colours won't flow. Leave the sheet to dry.

Use compasses to draw some small circles (2 cm average) on the sheet. Draw wider circkels around them. Fill the sheet with those circles and half ones near the edges.

Draw lines from the middle of the circles to the edges. Be sure it's an even number of lines and  Kkeep the lines as much as possible equidistant from each other. Color the squares alternating with a black marker or pencil.

Op art hands

You need:

1. drawing sheet
2. pencil
3. ruler
4. markers 

Draw a grid on the sheet with squares from 2 cm by 2cm. Draw your hand or an object with a pencil. Color this alternately with black an a color of your choice.  Color the background squares with the same colors, but so that the checkerboard pattern reverses.

Where Keith Haring meets Piet Mondriaan

You need:

1. drawing sheet A2 size
2. black strips 1,5 cm wide
3. colored construction paper in red, yellow and blue
4. ruler
5. scissors
6. glue
7. black marker

This is a teamwork lesson for two students. 

Draw squares and rectangles of various sizes on the colored paper. Make sure they are straight: start from a right angle and measure carefully. Cut the squares and rectangles and spread them on the white sheet.  Make sure same colors do not touch each other and stick them. 

Continue with the black strips. Decide by yourself how many strips and where you want them, but there are four requirements:

• the strips must be sticked straight! (use your ruler)
• black strips must be sticked around all colored area's
• use the black strips to create white area's (squares and rectangles) 
• don't use to much glue. Let some strips stay loose so you can put a Haring figure behind it

Draw three or more Keith Haring  characters on the colored paper. Cut them and paste them on the Mondriaan sheet. Be sure there is no yellow character on a yellow area. 

Outline the characters with a black marker and draw some 'move stripes' around them.

Picture book illustration

Students of grade 6 made this illustration. After a good study of the original illustration in a Dutch picturebook, they made a list of required materials to use for this artwork. The faces and arms are painted, the clothes and curtains are cut out of fabric, the wallpaper comes from a sample book for wallpaper and the flags are from scraps of paper.
