Hello class! Today we are going to talk about integers.
Does anybody know what 5-7 is?
That was a good guess Vanessa, but actually the answer is -2!
That's easy Mr. Jacobs! The answer is 2!
Huh?! James why is that???
Well I think when you subtracted you automatically took the smaller number from the bigger number right? When Mr. Jacobs asked what 5-7 is, he is asking us to take 7 copies of one from 5 copies of one.
I don't understand, there is not enough to take away though?
Yes! Thank-you so much Wes, I understand now.
I can help you Vanessa! We know 7 is not enough to take away from 5, so we take away the 5 and 2 more. After we take away 7, we have -2 left. Does that make sense?
Yeah, thanks guys!
Boys, notice the way you helped Vanessa without making her feel bad, that is great team-building! I am proud of you all.
