Children loves playing with cars and toy trucks. However running those cars and trucks across wet paint on is triple fun as they can see the track marking made from those toys criss crossing in various colours.
According to Allison McDonald (B.A, B.Ed, M.S) in her website No Time For Flash Cards, painting with toy vehicles helps kids develop creative thinking since we are using the toys for something other than their intended purpose. (https://www.notimeforflashcards.com/2008/07/things-that-go-go.html)
To do this activity, prepare paints of various colours, a variety of toy cars and trucks (or any vehicles) and large paper. Squirt some paint on the paper and let the children run those trucks on the paint on the paper.
