Adding Ones (Preparing to Carry)

5 ones + 8 ones

= 13 ones

= 10 ones + 3 ones

= 1 ten + 3 ones (We know that 10 ones = 1 ten)

= 13

A. Add ones for each of the following:

1. 8 ones + 5 ones 2. 6 ones + 7 ones

= ones = ones

= ones + ones = ones + ones

= ten + ones = ten + ones

= =

3. 7 ones + 9 ones 4. 8 ones + 3 ones

= ones = ones

= ones + ones = ones + ones

= ten + ones = ten + ones

= =

5. 7 ones + 6 ones 6. 9 ones + 4 ones

= ones = ones

= ones + ones = ones + ones

= ten + ones = ten + ones

= =
