• 196 pieces let a large group build over 16 spherical models at the same time.
• Concrete models support Quality First Teaching before pictorial and abstract work.
• Dishwasher safe at 70°C, so shared pieces are simple to keep clean.
• Useful in SEND provision, intervention groups and maths clubs.

For parents and home use

• Suits home educators, tutors or families who want enough pieces for several children.
• Joining the pieces gives regular fine motor practice.
• The Exploring Sphera booklet gives adults ready-made activities.
• Open-ended building lets children design their own curved models.

Supporting learners with SEND and learning differences

Hands-on construction helps many learners with SEND and learning differences understand maths ideas that can feel abstract on paper. Curved shapes such as spheres and cones are hard to draw and picture, but a Sphera model can be held, turned and taken apart. The 4 colours give clear visual cues, and joining pieces builds fine motor control. Building the same shape several times with a partner gives useful repetition.
