A lot of cutting this was. The basic idea was for the children to comprehend and accomplish understandment of third dimension and size diversity. I personally find third dimension hard to explain. These children are between 5 and 6 years old.
We started with the smallest cloud making it bigger and bigger. Children glued cardboard spacers between each cloud and produced these beautiful sculptures.
In addition one could also add a learning process of colours. We just did whatever we liked this time but it could be a lesson on warm and cold, primary and secondary or opposite colours.
