Add 2-Digit Numbers (No Regrouping): what children learn

Adding in columns lines up ones under ones and tens under tens. When the ones add to less than 10, nothing needs to be carried.

Add 2-Digit Numbers (No Regrouping): worked example

35 + 42 = 77

5 + 2 = 7 ones and 3 + 4 = 7 tens, so 35 + 42 = 77.

Add 2-Digit Numbers (No Regrouping): a common mistake to watch for

Kids sometimes forget to line the digits up, so ones get added to tens.

Add 2-Digit Numbers (No Regrouping): how to help at home or in class

Write each problem on graph paper with one digit per square so ones sit above ones and tens above tens. Have your child add the ones column first, saying "ones first" aloud, then the tens. For a hands-on version, build 24 and 51 with ten-rods and unit cubes and push like pieces together. When a whole row of problems is lined up neatly and correct without hints, they are ready for problems where ones add to ten or more.
