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.
