Numbers to 100: I can count and read numbers to 100.

1. Here are 100 counters.

   There are 10 rows, with 10 in each row.

   Ten tens make 100.

   Picture: An array of 10 rows of 10 counters.

2. Let's count on from 57.

   58, 59 …

   60, 61! After 59 comes 60.

   Picture: A number line from 55 to 62. A dot at 57 labelled "start". The frog hops from 57 to 58, then to 59, then to 60, then to 61.

3. Your turn: What comes after 89?

   Picture: A number line from 86 to 92. A question mark at the 1st tick after 89.

   Choose one:

   • 80
   • 90
   • 99

   Answer

   The answer: 90

   89, then 90. After 89 comes 90.

   Picture: A number line from 86 to 92. A dot at 89 labelled "start". The frog hops from 89 to 90.
