Teaching guide

What students learn

See 10, 20, 30 and the other multiples of ten as that many tens with zero ones left over.

How to teach it

Count in groups (2s, 5s, 10s) with a number line or hundred chart, highlighting the pattern in the ones digit. Link 5s and 10s to clocks and money.

Worked example
Count the tens rods and the ones blocks. What number do they show?
Answer: 81
Why: 8 tens = 80, 80 + 1 = 81

Generated and checked in code, so it is correct.

Watch out for

Losing the pattern partway, especially crossing tens (e.g. 28, 30 skipped) or reverting to counting by ones.
