Exciting day today! Two teams filmed stop motion sequences for films showing how addition and multiplication properties work. This is after working with the properties in our math books, writing about them collaboratively on paper and then using Chromebooks, and providing feedback on multiple drafts. Several teams are on third or fourth drafts, and their writing SOUNDS better for it!
We are making sure to keep our feedback kind, specific, and helpful. And I’m SUPER proud of students for being reflective and excited to make their next draft better!
Kudos to Zaya’s team on finalizing their script/essay. Want to read it for yourself? Take a look!
Commutative Property of Addition
by Lila Epstein, Trevor Wagner, Zaya Jelani
Hi i’m Trevor. Hi i’m Lila, and I’m Zaya.
We are going to show you how the commutative property of addition works. It isn’t as complicated as it might seem.
The commutative property states that that you can move addends in an expression and the sum is equivalent.
For example: 4 + 5 + 1 = 4 + 1 + 5. If you add them, the value is the same.
The commutative property can make numbers easier to add. For example, take
9 + 7 + 1. If you use the commutative property of addition, you can switch 7 and 1 to make it 9 + 1 + 7. Following the order of operations, we add 9 + 1 to make a 10. And adding 10s are easy, because they have zeroes! We think adding 10 and 7 is easier than adding 9 and 7 and then one more.
