Introduction to Negative Integers - Remix

Introduction to Positive and Negative Integers

These are short movies and powerpoint videos that I made in 2012 (I think) to help students understand integer operations.   More recently, I've published a more thorough introductory lesson. https://www.oercommons.org/authoring/13198/1/preview  

 Introduction to Integers:   how can you add something... and end up with less?   This little story introduces the idea of the "opposite" nature of integers. http://www.resourceroom.net/math/722IntroIntegers/722IntroIntegers.html

Adding integers of the same sign -- this is via Camtasia, with quizzes interspersed in the video.  (You can push the little "play" thing along and get past the quizzes, though.)

Absolute Value -- how can you be absolutely positive about absolute value?   A visual-kinesthetic approach can help :)

Adding integers with different signs -- lesson with practice and review of adding same-signed integers

More Powerpoint Shows:  

Subtracting Integers - adding the *opposite* :)

Subtracting positive integers from negative integers --

and, finally...

Subtracting Negative Integers -- taking away a bad thing is giving you a good thing!

Distributive property review -- flash movie

Author's note:   I used the "chips" approach but will be adding parallel lessons using the number line.
