PRODUCT OVERVIEW

734-1/2: COCK,DRAIN.

Our Rainbow Architect Arches are made from beautiful smooth solid beechwood with a natural woodgrain finish in the seven different colours of the rainbow. The arches nest together as a set with the inner block being a solid 3D semicircle. This shape set will allow your child to unlock their creativity and innovation.

Learning through play, the nesting set can be used to compliment the design and construct of towers, sculptures or create homes for small world play people or animals, whilst encouraging and developing mathematical logic to sort the shapes by colour or size; exploring size and scale; using mathematical language (larger, smaller, taller, wider) and for improving language skills and descriptive vocabulary. This part is cataloged in the U.S. Government catalog under NSN 4820-00-287-3552, indicating validated use in U.S.
