After completing this lesson, the child should be able to:

  • Count from 1 to 20
  • Recognize the teen numbers 11โ€“19
  • Count by twos to 20
You can count to 10 โ€” amazing! Now let us meet the tricky teen numbers and count all the way to 20.

The teens

After 10 come the teen numbers. Say them slowly:

11 eleven ยท 12 twelve ยท 13 thirteen ยท 14 fourteen ยท 15 fifteen ยท 16 sixteen ยท 17 seventeen ยท 18 eighteen ยท 19 nineteen ยท 20 twenty

Tens and ones

Here is the trick: 15 means one ten and five ones. Ten fingers plus five fingers! Every teen number is a ten with some ones riding along.
