In this Grade 2 worksheet, students add 3-digit numbers where no regrouping is needed. Each column adds to 9 or less, so kids practice stacking numbers by place value and writing the totals straight down. The mix of fill-in problems and true-or-false statements helps students build confidence with the standard algorithm. This is the first step in Grade 2 toward adding within 1000 and sets up later practice with carrying across the tens and hundreds places.
