Counting to 120: a worked example (98, 99, ___, 101)
- Say the numbers you can see: 98, 99.
- After 99 the ones start again at 0 and the tens go up: 9 tens become 10 tens.
- 10 tens is 100, so the missing number is 100.
- Check that it fits: 100 comes just before 101.
How to use it at home and in class
At home
Part A suits kindergarten: ask your child to touch each star as they count, or cross it out with a pencil. The stars sit in rows of 5, so a full row can be counted as 5. Parts B to D suit the end of kindergarten and grade 1. Read each row of numbers aloud together before writing. Part D crosses 100, which is where most children slip. The counting to 120 lesson shows the pattern on a chart. Ten problems a day works better than a whole sheet at once. Mark them together with the answer key, then ask your child to explain one they got wrong: finding the mistake themselves is where the learning happens.
In class
Use the first row as a warm-up, a full page for independent practice, or five questions as an exit ticket. For a retake or a second group, make a new version with the test maker so every child gets different numbers.
Mistakes to watch for
- Counting a star twice, or skipping one, in Part A.
- Writing 910 after 99 instead of 100.
- Counting forward in Part C when the numbers go back.
- Adding an extra zero once the numbers pass 100, so one hundred one gets four digits.
What to practice before and after counting to 120
- After: before, after and between, once this one is mostly right.
- Learn it first: the counting to 120 lesson and the numbers chart.
