Children who seek movement need more sensory input in their day to make sense of the information around them. 

Try: 
(1) Incorporating movement into activities (e.g. Jumping on the trampoline whilst spelling sight words or playing hopscotch whilst completing simple number recognition)
(2) Placing toys in difficult to reach places to promote climbing and crawling
(3) Encouraging your child to engage in a physical activity before starting a thinking task (e.g. Crab walks or planks)
