Activity
The activity on this page helps students to understand the difference between “teen” and “ty” numbers.
The words and numerals are connected to concrete materials – in this case, groups of 10 beans and single beans. When 10 beans have been counted, place them in an opaque film canister with the lid on. This will encourage the students to move from relying on concrete materials to working with a mental image of the beans and to counting in tens as they count each canister.
It may also be helpful to exaggerate the “teen” syllable when counting these numbers with the whole class or with a group.
As an extension, the students could count in te reo Māori. Counting in Māori will consolidate the students’ understanding of the difference between “teen” and “ty” numbers. The students need to understand the difference between “teen” and “ty” numbers before they can move on to part-whole thinking.
Tekau means 10, and mā means “and” or "+".
