Grimm's Counting Rainbow

The Counting Rainbow is a 10 piece wooden rainbow that belongs to Grimm's number themed play. Rather than printing numbers or fractions on the pieces, it lets children sense quantity and order through stacking, nesting and sorting. It measures about 27.5 cm long and 13.5 cm high, so the arcs are a comfortable size for young children to handle.

Children explore quantity and order by playing and using their senses rather than following one correct answer. They can line the ten arcs from largest to smallest, nest them, or match pieces that belong together. This open approach lets each child make their own sense of grouping and counting through free play instead of drills.

The ten arcs are made from lime wood and finished with a non-toxic water based colour stain. The stain keeps the wood grain visible, so the rainbow feels natural to hold under its bright colours. Because the pieces are coloured by hand, small differences in tone between arcs are normal and give each set its own character.

Beyond counting play, the ten arcs stack into a classic rainbow, nest inside one another, or turn into tunnels, bridges, fences and hills for small world scenes. Standing them upright or laying them flat changes what they become. The open shape means children keep finding new uses as their imagination leads the play.

Grimm's recommends the Counting Rainbow from around 3 years. At this age children enjoy sorting, ordering and building their own scenes, and they can handle the ten separate arcs. Because play is open rather than fixed, the same rainbow stays useful for several years as counting and building skills develop.

Yes. The arcs mix well with other Grimm's rainbows, building blocks and loose parts, so they can join a larger scene as bridges, roofs or rolling tracks. Combining sets adds more colours and sizes and keeps building varied as children collect more Grimm's pieces over time.
