Compare the tens. The number with more tens is greater. If the tens match, compare the ones. The wide, open side of > or < faces the greater number.

Watch for: Comparing the ones first, so 29 looks bigger than 31. Pointing the open side of the sign at the smaller number. Thinking a number with bigger digits in any place wins: 19 > 21.
At home: Each draw two number cards and make the biggest two-digit number you can. Say who wins with “greater than” or “less than.”
