Promote visual motor skills and improve finger isolation. In addition, work on processing of tactile input as the child moves his fingers along the paint.
For this activity, use a gallon size Ziplock bag.
Place approximately 1/2 cup of tempera paint in the ziplock bag, remove air and seal. Work the paint around until it filled the bag.
Have child make lines, shapes or letters by moving his finger along outside of the bag.
As an alternative, you can use shaving cream mixed with food coloring instead of the tempera paint.
