About this worksheet
Twenty problems in columns, mostly three-digit plus three-digit, with four that add a two-digit number to a three-digit one (529 + 46, 362 + 81, 47 + 638 and 816 + 75). Every problem regroups at least once, some regroup twice, and every sum stays under 1000.
The two-digit addends are the ones to watch. Lining 46 up under 529 so the 4 sits in the tens column is where most of the mistakes on this sheet come from.
