What students learn

Say, show and put in order numbers from zero to at least twenty, using real and on-screen materials and numerals.

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

1, ___, 3, 4, 5

Answer: 2

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.
