Teaching When Ones Make a Ten

What it is

A guided lesson on two-digit addition when the ones make more than nine. Ten ones are traded for one ten in a tens and ones chart, and the carried ten is written above.

When a child is ready

Ready once two-digit addition without carrying is easy.

If they struggle

Add the ones first and say the total as tens and ones: twelve is one ten and two ones. The ten goes above the tens column and the two stays below.
