Adding with base ten blocks

Teaching Transcript

🎙️

Let's add the first set of blocks, which has 23 blocks, to the second set, which has 19 blocks.

🎙️

We start with the smallest place value, the ones. When we add them together, we have a group of 12 ones.

🎙️

Since there are more than 10 of them, we can create a long ten block, which leaves 2 ones.

🎙️

Now we add the ten blocks, including the one that we created from our ones

🎙️

So 23 plus 19 give us a sum of 42

This math skill teaches adding numbers using base ten blocks, including carrying over when the sum in the ones place exceeds ten. The process involves grouping ones to form a new ten block and then adding the ten blocks together to find the total sum.
