Gee eers vir die leerders los vorms om in tiendes te verdeel, sodat hulle self kan ontdek dat tiendes , net soos derdes en vyfdes bereken en gemeet moet word. Dit is nie net 'n kwessie van vou en weer vou.

Lei hulle om te ontdek dat as hulle eers vyfdes kry, dan kan hulle elke vyfde in die middel deel om tiendes te kry.

Gesels met die leerders oor simetriese vorms . Laat hulle voorwerpe in die klas wat simetries is, identifiseer. Hierna behoort hulle die prent te kan voltooi.
