## Math Grade 6 Unit 4: GEOMETRY

#### Number Line (Prerequisite)

## 01

Understand a rational number as a point on the number line. Extend number line diagrams coordinate axes familiar from previous grades to represent points on the line and in the plane with negative number coordinates

#### Adding Integers

## 03

1a. 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.

1b. 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.

1c. 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.

1d. Apply properties of operations as strategies to add and subtract rational numbers.
