When wanting to introduce the children to the vocabulary of cool and warm colours I used the seascapes to help them divide their paper.
We used oil pastels to create seascapes with a warm colour section and a cool colour section. The children used warm for the sun and cool for the water. They used wavy lines for the sea alternating colours then used curved lines for the sun in warm colours.
The results for 7 and 8 year olds were stunning.
