Supporting learners with SEND and learning differences

Hands-on construction helps many learners with SEND and learning differences understand shape ideas that can feel abstract on paper. Open frames show the edges of a shape and solid pieces show its faces, so children can compare them by touch and sight. Joining pieces builds fine motor control, and models with swivel joints give a satisfying, visible result.
