Look at this addition.

16 + 1 = ?



Start at 16 and count 1 forward.

What do you get then?

Use the number line below to help you.

16 + 1 = 17


number line up to 20


How about this one?

22 + 2 = ?

This time, we start at 22 and count 2 forward. Again, you can use the number line to help you.
