Teaching guide

What students learn

Count to 100, counting on by ones and by tens. Builds early number sequence fluency.

How to teach it

Count real objects out loud, touching each one once, then match the count to the written numeral. Practise counting on from a number, not always from one.

Worked example

7, 8, ___, 10, 11

Answer: 9

Generated and checked in code, so it is correct.

Watch out for

Skipping or double-counting objects (weak one-to-one correspondence), and thinking the last number said is just a label rather than the total.
