Area of School Readiness

Perceptual, Motor, and Physical Development: According to the Head Start Early Childhood Learning & Knowledge Center, perceptual, motor, and physical development includes motor development and health, safety and nutrition. This includes gross motor or large motor skills (like jumping, running, climbing) as well as fine motor or small muscle skills (like holding a fork or buttoning a coat). Health, safety, and nutrition includes skills for self-care (like brushing teeth), knowledge promoting healthy eating habits, and personal safety routines.

Cognition: According to the Head Start Early Childhood Learning & Knowledge Center cognition is your child’s ability to reason, use their memory, engage in problem solving and thinking skills that help children learn about and understand the world around them.  

Purpose of the Activity

Gross Motor and Fine Motor Skills: Your child will practice using the muscles in their arms and hands as they explore and paint with the marshmallow dough. 

Exploration and Discovery: Your child will explore the gelatin as they play and explore the dough.


  1. Combine marshmallows and 2 teaspoons coconut oil in a microwave safe bowl.
  2. Microwave about 30 seconds (until the marshmallows are fluffy), watching closely so as not to cook them too long.
  3. Add a couple drops of food coloring, if desired.
  4. Add 8 tablespoons cornstarch and mix the dough with a spoon or mixer until it thickens. If dough is still sticky, add additional cornstarch (1 tablespoon at time, up to 6 total) and knead (massage) the dough with hands until it is smooth and ready to use.
  5. Let your child play with the marshmallow dough and encourage them to explore and even taste it.
  6. Store in airtight container until ready to use & enjoy!
