What's on this worksheet
Two four-digit numbers. Regrouping can happen in any column, so some sums have five digits. Each sheet comes with an answer key on a separate page.
Teaching tips
Neat columns matter more as numbers grow. If alignment slips, try grid paper with one digit per square.
Check answers with subtraction: the sum minus one number should give the other.
