Numbers from 1 to 50
We can count all the way from 1 to 50! After 20 we keep going: 21, 22, 23 ... up to 50. Each group of ten has a name: 10 (ten), 20 (twenty), 30 (thirty), 40 (forty), 50 (fifty).
Example
Counting in Tens
🔟🔟🔟🔟🔟 — Count by tens: 10, 20, 30, 40, 50!
If you have 3 groups of ten and 4 extra: that is 34.
2 groups of ten and 7 extra: that is 27.
Tens and Ones
Every number has tens and ones. The number 35 has 3 tens and 5 ones. The number 42 has 4 tens and 2 ones. This is called place value!
