This title features triangular pennants, diamond-shaped kites, circular moons and a great big gold star for Freddie the bunny's perfect quiz! That's just the start, as Richard Scarry goes on to explore lines (zig-zag, parallel); directions (left, right, around, between); sizes (big elephant, small mouse); amounts (full and empty); and opposites (soft pillow, hard wooden stool). With so much fun throughout, learning is a delight.
