Ten Counting (1st and 2nd)

100

3 ones + 4 ones

= 7 ones

= 7

200

6 ones + 4 ones

= 10 ones

= 10 

Or 1 ten

300

6 ones + 5 ones 

Say the answer and then say how many tens and ones there are.

11 ones

This is the same as 

1 ten and 1 one

400

8 ones + 4 ones

Say the answer and then say how many tens and ones there are.

= 12 ones

= 12

= 1 ten 2 ones

500

12 ones + 5 ones

Say the answer and then say how many tens and ones there are.

= 17 ones

= 17 

Or 1 ten and 7 ones
