Numbers up to 100

Counting to 100

Count in ones: 1, 2, 3 ... 100. Count in tens: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100.

Place value

Number	Tens	Ones
23	2	3
47	4	7
90	9	0

In 47, the 4 means 40 and the 7 means 7, so 47 = 40 + 7.

Comparing

Use greater than, less than and equal to. 58 is greater than 49 because 5 tens is more than 4 tens.

Try it

1. Write the number that is 10 more than 34.
2. Arrange 72, 27, 45 from smallest to biggest.
