Suitable for Grades: 6th Grade, 7th Grade
CCSS: 6.NS.C.6, 7.NS.A.1
CCSS Description: Understand a rational number as a point on the number line; extend number line diagrams and coordinate axes to represent points with negative coordinates.
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. 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. 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. 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. d. Apply properties of operations as strategies to add and subtract rational numbers.
Enhance your students' understanding of absolute values with this worksheet where they will be comparing the value of different expressions. Expressions are in the form |x|, |-x|, -|x| and -|-x| where x is either an integer, decimal or fraction.
In Section A, learners will sort expressions according to their value into a table of 4 columns.
Section B sees students choosing the expression with the highest value out of a pair and using inequality symbols to compare pairs of expressions.
Then in section C, learners will put expressions in ascending order according to their value.
