This big pentagon is a great beginner geometric puzzle. It's made up of 21 solid-wood blocks that are 1.5 inches thick and 2 to 5 inches long. The blocks are easy to manipulate into patterns and designs both inside and outside of the sturdy wooden frame, and can also be used as building blocks. The geometrical mosaic puzzles encourage the feeling for colors and forms in play, three-dimensional thinking and inner flexibility.
11 inches across, 1.75 inches thick, colored with non-toxic water-based dyes. Age 3 and up.
