James and Hannah are using base ten blocks to help them find the sum of 26 and eight. Their teacher asked them if they will need to regroup when adding. Who is correct? Hannah says, “No.” James says, “Yes, we need to make 10 ones into another ten.” Find the sum. 26 plus eight equals what?

James and Hannah are using base ten blocks to help them add 26 and eight. The number 26 has two tens and six ones. And the number eight has eight ones. First, we need to add the ones. We have six ones and eight ones. Their teacher asked if they need to regroup. What is six plus eight? 14. There are 14 ones altogether. So do we need to regroup? Yes, we do. James is right.

We need to take 10 ones and make them into a tens block. We need to exchange 10 ones for one 10. Let’s take 10 ones. One, two, three, four, five, six, seven, eight, nine, 10. Then we can exchange the 10 ones for one 10. Now we have four ones and three tens. So James was correct. We did need to regroup. The sum of 26 plus eight is 34.
