Adding 2 Digit Numbers with Regrouping

Addition 2-Digit by 2-Digit (With Regrouping)

Description: Learn how to regroup (carry) when adding two 2-digit numbers.
Student Tips:

• Add the ones place first. If the sum is 10 or more, regroup by carrying to the tens.

• Add the tens place next, remembering to include any carried number.

• Rewrite neatly so you don’t lose track of your carry.
  Teaching Instruction: Demonstrate regrouping with base-ten blocks or drawings (show how 10 ones become 1 ten). Gradually move from manipulatives to written problems, reminding students to always check their work.
