Adding two-digit numbers without regrouping teaches the column habit: add the ones, then add the tens. Because no column goes past 9, students can focus on lining up digits by place value.

What's on this worksheet
Both numbers have two digits. Neither the ones nor the tens add up to 10 or more, so no carrying is needed. Each sheet comes with an answer key on a separate page.
Teaching tips
Always start in the ones column, even though the order does not matter yet. It will matter on the next sheet.
Base-ten blocks (rods and units) make each column visible.
Move on to regrouping once students line up digits correctly without reminders.
