Integers

Using a number line to add integers.

A vertical Number line.
Just in case:
Zero pair - A pair of integer chips with one chip representing +1 and 1 chip representing.
Opposite integers - Two integers with the same numeral but different signs.

(+2) + (+3) = 5
(-4) + (-2) = -6
(+3) + (-2) = 1

Positive Numbers move right. Negative numbers move left.
A number line can be vertical also.



Page 319 - 322 is homework! :]

  1. Great post Maya! You covered pretty much everthing of what we learned today in class, and it was easy to understand. A mistake you made was when you were talking about zero pairs, you forgot to say -1, also the word page was kind of hard to see, but thats okay. I liked how you gave us a website and video link, and I liked the pictures too. Keep up the good work Maya!:)

  3. Good job Maya. I loved the pictures. I think that you could've highlighted some more key points though, such as the word left and right. I liked that you included links. Thanks for the reminder of the homework. Keep up the good work. (:

  15. Good job! Your post was very simple and very good. However your vertical number line picture was messed up (it should go completely up and down). You should embed your video next time. Good job anyways.

  18. Good post Maya(: I like how you included pictures to help us understand it more. One thing you can do next time is that for the key words like "Zero Pair" is that you can maybe add colour to that so it'll stick out more.
