Oct. 12-16
This week we will begin Topic 2- Integers and Rational Numbers.
Learning Objectives
- Two numbers with opposite signs, such as 5, and -5, are equidistant from 0 on the number line.
- Number lines may be displayed horizontally or vertically. This does not affect a number’s value.
- 0 is the point at which direction or value changes.
- The opposite of an opposite of a number is the original number.
- The coordinate plane is two number lines intersecting at 0, effectively called the x- and y- axes.
- As such, the coordinate plane extends infinitely
- The further left a number is from zero, the more negative (smaller) it is.
- The further right a number is from zero, the more positive (larger) it is.
- When comparing any two numbers on a number line diagram, the number to the left is always smaller if the number line is oriented from left to right.
- The further a negative number is from zero, the smaller the value.
- The further a positive number is from zero, the greater the value.
