A teen can split differently

Make a two-part organiser for fourteen pieces. 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: Bookmark blanks, Card-game pieces, Picture shapes. Use a smaller amount when useful. An empty part is zero.

Grown-up help

Full teacher plan. If ten-and-ones is the only accepted split, physically move two objects between parts of a different teen. Check each part and recombine. If equal sharing is imposed, choose two jobs with different needs. 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.
