Goal: Regroup to find the sum.

Let’s try regrouping to add! You can use this addition page to help.

34 + 27 = __

Math equation: 1 empty box, in the remainder section. 2 empty boxes + 2 empty boxes = 2 empty boxes

The first addend is 34. Write the digits 3 and 4 on two number cards, then put them into the correct boxes on your paper. Click Show Me to check your work!

34 + 27 = __

1 empty box, in the remainder section. 34 + 2 empty boxes = 2 empty boxes

The second addend is 27. Write the digits 2 and 7 on two number cards, then put them in the correct boxes on your paper. Click Show Me to check your work!

34 + 27 = __

1 empty box, in the remainder section. 34 + 27 = 2 empty boxes. The 4, 7 and empty box in the ones area, are circled in red.

Now we can add the digits in the ones place! 4 + 7 = 11. 11 is made up of 1 ten and 1 one. Write 1 on two different number cards. Keep a 1 under the ones place and carry over the other 1 over the tens place. Click Show Me to check your work!

34 + 27 = __

1, in the remainder section. 34 + 27 = 1 empty box in the tens section, and 1. 1, 3, 2 and the empty box are circled in red.

Let’s add the tens place now! What digit will you write on this last card? What is 1 + 3 + 2? Click Show Me to check your answer.

You did a great job finding the sum! Practice regrouping on the worksheet below. When you are done, turn in your assignment to your teacher with your Weekly Written Work.
