Reading and writing numbers to 100
Read and write numerals from 0 to 100
What a learner can do afterwards
- Read two-digit numerals up to 100 correctly
- Write any number 0–100 as a numeral from dictation
The lesson
Numbers from 10 to 99 have two digits. The first digit shows tens. The second digit shows ones. One hundred is special: it has three digits.
Tap each dot and count out loud.
Try it together
Mia has 52 stickers. She counts 5 tens and 2 ones. She writes the number 52.
Good to know
Look at the first digit for tens. Look at the second digit for ones. That tells you the whole number.
Two-digit numbers have a tens digit and a ones digit.
