Addition in Grade 4
By fourth grade, students add multi-digit numbers fluently using the standard algorithm — lining up place values and carrying through the thousands. The skill is the same as earlier grades, just with bigger numbers and more careful place-value tracking. These worksheets scale from three-digit review up to numbers within 10,000.
3,468 + 2,957 = ?
- Ones: 8 + 7 = 15 — write 5, carry 1.
- Tens: 6 + 5 + 1 = 12 — write 2, carry 1.
- Hundreds: 4 + 9 + 1 = 14 — write 4, carry 1. Thousands: 3 + 2 + 1 = 6.
- Answer: 6,425.
