Power of Ten (Trevor Calkins)

The Power of Ten System is a set of visual tools (ten-frame cards, place value cards and ten-frame egg cartons) designed to help students develop the fundamental underpinnings of number sense and is based on the premise that over eighty percent of learning is visual (unless the student is severely visually disabled).

Students need to be able to look a set of objects and know how many there are without counting.
