16 large hardwood blocks containing beads, transparent acrylic, coloured sand and water/glitter filled pockets in 4 different shapes (square, rectangle, triangle and semicircle). The Sensory Blocks will promote observation in the wider sense, as all the shapes follow the same convention of colour and shape. So for example, regardless of the contents of the block the squares are always red. The combination of smooth hardwood exterior and the brightly coloured sensory centre makes a fascinating component with a multitude of educational possibilities for use with children of all ages.
