Painting with water is a great activity to encourage children to make marks and allow them to work on a large scale BUT keep things pretty mess free.
All you need is a paintbrush, a bucket some water and a wall or large surface.
Once finished… within a few minutes the writings and pictures will disappear ready for more mark making.
This activity is really good for any children who hold pens in a full grip as it encourages them to try a different grip. It’s really hard to use the brush in an upright position when you’re using a full grip.
