Add Four 3-Digit Numbers in Columns: what children learn
Adding four numbers in columns is the same method with one more row. The ones can add to 30 or more, so up to three tens may be carried into the next column.
Add Four 3-Digit Numbers in Columns: worked example
112 + 235 + 140 + 213 = 700
2 + 5 + 0 + 3 = 10 ones: write 0 and carry 1 ten. 1 + 3 + 4 + 1 + 1 = 10 tens: write 0 and carry 1 hundred. 1 + 2 + 1 + 2 + 1 = 7 hundreds. So the sum is 700.
Add Four 3-Digit Numbers in Columns: a common mistake to watch for
With four rows, kids often skip a number or forget a carried digit.
Add Four 3-Digit Numbers in Columns: how to help at home or in class
Make a relay of it: your child reads each column aloud, digit by digit, while you tick every number as it is added so nothing gets skipped. Teach a scan for pairs that make 10, like 3 and 7 or 4 and 6, and add those first to keep running totals small. Once four rows feel as comfortable as three, your child is ready to look at how far a number sits from 1,000.
