Three parts can make one whole

Make a three-section organiser. Choose safe pieces, marks, tactile objects or tell an adult where to move them.

  1. Show the whole and each part.
  2. Try another split using the same objects.
  3. Check what stayed the same. Keep a useful plan or change it.

Choose a job: Picture pieces, Game marks, Blank notes. Use a smaller amount when useful. An empty part is zero.

Grown-up help

Full teacher plan. If the third part is omitted, put every object in one of three distinct places and audit coverage. If fairness distracts from the target, choose three jobs that deliberately need different amounts. Use local safe materials and usual communication/access supports. Child-directed adult physical work and child mathematical choice stay distinct. Preserve first thinking before feedback; a drawing is not an actual outside inventory or performance event.
