Print and laminate 3 pages (back to back if possible)
Collect shells from the beach as an extra activity for you and your tamariki and then use a marker to write 1 pūreta on each anga.
Give your tamaiti one sheet at a time and also give them the matching pūreta, to make things easier. Then help them match the shell with the shell on the paper.
If you don't have real life shells, print two copies and cut them out.
