Addition with Regrouping
2 digits + 1 digit
 Write the 2 digits + 1 digit problem
horizontally.
 Students rewrite the problem in “working
form” while reading the problem aloud
splitting the tens and ones in the two digit
number.
Ex.
35 + 8 =
“Three tens, five ones”
3 5
“Down and to the left plus eight ones” +
8
“Equals”
