What's on this sheet

The pairs are built so that a child cannot get by on one digit. 135 and 153 share a hundreds digit, so the tens decide. 867 and 863 share two digits, so the ones decide. 861 and 761 are settled by the hundreds, even though the rest of the digits match.

Why this sheet works

The hardest pairs have a zero in them. In 990 and 909 the digits are nearly the same, and the 0 in the tens place is what makes 909 smaller. 305 and 350 work the same way. A child who can explain those two has understood place value and not just the rule, and a pair like 802 and 802 keeps the equal sign in play.

How this one works

110 ? 170

110?170
110<170
  1. Both have 3 digits, so read them from the left.
  2. The digits before that match, and the next ones differ in the tens place: 1 and 7. 7 is more, and nothing to the right can change that.
