A set of construction bricks in two sizes that light up and change colour when they are turned. Perfect for using ICT to learn sequencing. Each cube requires 2 x AA batteries (not included). Children will love turning the blocks in their hands to see which colour they will change to next. Why not incorporate them into other construction resources to add excitement and increase engagement with ICT. They are wonderful when combined with natural or see-through bricks to create a light up igloo or a coloured window. Wipe clean with damp cloth. Do not submerge in water.
