Guidecraft Rainbow Blocks – Sand

This is a set of eight blocks with smooth hardwood frames and primary coloured acrylic windows filled with colourful sand. The set contains four rectangles and four half moon shapes, sized to standard unit block measurements so they combine with other classic building blocks for taller, more varied builds.

As children tilt and turn the blocks, the coloured sand shifts behind the translucent windows, catching the light and creating an adventure in colour and gentle sound. Combining blocks blends new colours, and stacking them in a new order each time forms fresh shapes, keeping sight, sound and touch involved in every build.

The set includes four rectangular blocks and four half moon blocks, eight pieces in total. The half moons introduce curves and arches to a build while the rectangles form walls and towers. Because they follow standard unit block sizing, they stack neatly and pair with other unit blocks a child may already own.

Yes. The primary coloured, translucent windows are made for light table activities. Placed over a light source, the sand filled panels glow and the colours deepen, helping children explore colour, light and visual perception while they build and rearrange the blocks.

Each block has a strong, smooth hardwood frame fitted with a primary coloured, transparent plexi window. Behind the window sits sealed, colourful sand. The solid frames stand up to stacking and knocking, and the sand stays enclosed so it moves and shimmers without spilling.

Guidecraft recommends these blocks for children aged two and up. The chunky hardwood frames are easy for toddlers to grip, while the shifting sand and colour mixing keep older children engaged as they experiment with building, balance and how light passes through each block.
