Adding integers: LearnZillion video
https://learnzillion.com/lesson_plans/5250-adding-positive-and-negative-integers-on-a-number-line/
-This video shows how to add integers (negative and positive whole numbers on a number line.
https://learnzillion.com/lesson_plans/6667-add-integers-using-a-number-line/
-This video links adding integers to real-life situations on a number line.
Additive Inverse: LearnZillion video
https://learnzillion.com/lesson_plans/6643-understand-the-additive-inverse/
-This video reviews that additive inverses are just adding opposites that result in 0,
so (+5) + ( -5) = 0. We also call these zero pairs.
Adding Integers with Counter Chips: LearnZillion video
https://learnzillion.com/lesson_plans/5608-add-integers-using-chips/
-This video shows addition with 2 color chips. It also reviews that although -4 uses 4 negative chips and +3 uses 3 negative chips, it does not mean that -4 is a larger number.Adding is combining of groups.
Distance versus Difference on a Number line: LearnZillion video
-This video shows the relationship between distance and difference, which help s to better understand subtracting integers.
-You could use this strategy of distance when subtracting integers, but you must find the distance between the values AND then look at where you started and where you ended. If you moved right it is positive, if you moved left it is negative.
Additive Inverse: LearnZillion video

-This video reviews that additive inverses are just adding opposites that result in 0,

Subtracting Integers using Number line and the Additive Inverse: LearnZillion
https://learnzillion.com/lesson_plans/5378-subtract-integers-by-adding-the-additive-inverse/
-This video reviews adding integers: same sign add and use that sign OR different sign you subtract and use the sign of the values with the larger absolute value. Then it continues to review the 3 interpretations of - which are “negative”, “ subtract” or “opposite”. Then combines that information to graph and solve subtraction integer problems.
Subtracting Integers with chips: Learn Zillion
https://learnzillion.com/lesson_plans/6765-subtract-integers-using-integer-chips/
-This video starts with a review of zero pairs ( a negative chip and a positive chip = 0)
It also reviews addition of integers (same sign, add and use that sign; different signs subtract and use the sign of the number with more chips) Adding zero pairs does not change the value on the mat. This also connects debt to negative values and subtraction. Then uses adding zero pairs of chips to explain subtraction of negatives.
