Set of puzzles consists of 12 clown pieces and 18 addition sentence pieces - 36 puzzles can be assembled in all. When assembled, each puzzle consists of 3 pieces: two clown pieces and one addition sentence piece.
Each clown piece is half a clown having a vertical cut down the center dividing his left and right sides. All puzzle pieces are straight cut. The straight cut requires that the student assemble each puzzle by perceiving parts-to-whole relationships, rather than by fitting together uniquely cut pieces.
