Shark Teeth Subtraction by Heidi Butkus is a great way to practice beginning subtraction skills in either a small group or large group setting. These worksheets and workmats are organized so that you can teach children to practice finding differences from three or four first, then five, six, and so on up to ten. I recommend that you begin with the smallest numbers first (differences from three and four) and then work your way up to the larger numbers. Perfect for TK, Kindergarten, or First Grade!
