Task 4:  Subtracting Integers Video Lesson

Task 4:  Subtracting Integers Video Lesson - In this video lesson we will learn how to subtract integers using integer chips.  We will also learn a rule for subtracting integers which will have you rewrite - keep, change, opposite.  We will also review rules for adding integers.  Student practice is embedded in the lesson and exemplar solutions are modeled.

Task 4 Instructions - Be prepared to take notes during the video and to independently complete practice problems.  Pause the video for each practice problem, complete your work independently, and resume the video to see the exemplar solution.

Common Core Math Standards - 

7.NS.A.1  Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram.

7.NS.A.1.A  Describe situations in which opposite quantities combine to make 0. For example, a hydrogen atom has 0 charge because its two constituents are oppositely charged.

7.NS.A.1.B  Understand p + q as the number located a distance |q| from p, in the positive or negative direction depending on whether q is positive or negative. Show that a number and its opposite have a sum of 0 (are additive inverses). Interpret sums of rational numbers by describing real-world contexts.

7.NS.A.1.C  Understand subtraction of rational numbers as adding the additive inverse, p - q = p + (-q). Show that the distance between two rational numbers on the number line is the absolute value of their difference, and apply this principle in real-world contexts.

7.NS.A.1.D  Apply properties of operations as strategies to add and subtract rational numbers.
