Numbers to 20 · Usually met around P1
Counting, reading and writing to 20
Ring a group of 10, then count the rest.
How to do it
Method
Ring a group of 10, then count the rest
1 ten and 4 ones = 14 (fourteen)
Another way
Ten frames
A full frame 10, the other 4 → 14
In full
When counting things, touch each one as you count it and never count it twice: the last number you say is how many there are. With many things, count out a group of 10 first, then count the rest: 1 ten and 4 ones make 14, read “fourteen”. Every number from 11 to 19 is ten and some more: a 1 in the tens place, then the ones. 20 is 2 tens. Or use ten frames: one full frame is 10, then see how many are in the second.
