First coloring book of its kind! This unique book contains 3 sets of 8 pictures. In each set the major lines that make up the drawing are of different widths. The lines of the 1" set are 1/4 in. wide and by the 3rd set the lines are down to 1/16 in. This concrete progression allows everyone; child, parent, and teacher/therapist, to take note of and document progress in hand and arm control. Additionally, the teacher now can give all members of the class the same coloring page regardless of their skill level. Works the same for scissor use and cutting skills.
