How to teach this

Have your child find the smallest number first, cross it off, then find the smallest of what's left. Saying the tens aloud, "3 tens, 5 tens, 6 tens," keeps the comparison honest. If two numbers share a tens digit, that pair is the teaching moment: the ones decide.

Watch for: Kids order by the first digit alone and stop. When the first digits match, the next place has to break the tie. Kids copy the numbers in the order they sit on the page. Read the direction first, least to greatest or greatest to least.
