This book really breaks down some of the steps to drawing Mat Man (handwriting without tears tool). This is for preschool and kindergarten age children with fine motor delays.
I suggest cutting out, laminating, and coiling the book together. Then, you can have the kids use dry erase markers to draw the missing body parts. The book progresses in difficulty until you are able to draw the complete Mat Man from scratch. Also good for identifying body parts, as you can ask which part Mat Man is missing.
