Adding 2 x 1 Digit Regrouping

Addition 2-Digit by 1-Digit

Description: Practice adding a two-digit number with a one-digit number to build fluency.
Student Tips:

• Line up the numbers so the ones are in the same column.

• Always start adding from the ones place.

• Double-check by counting on to see if your answer makes sense.
  Teaching Instruction: Model problems vertically and emphasize place value alignment. Use number lines or base-ten blocks to reinforce the idea of “adding on.”
