Are you ready?

Number lines help us work out distance and direction, and can be horizontal or vertical (think of a thermometer). Remembering how to plot points on a number line, will help us in this lesson. 

Plot the following numbers on the number lines:

  1. Plot $3$3 on the number line below.

    012345678910

  2. Plot $528$528 on the number line below.

    520525530

  3. Plot $700$700 on the number line below.

    05001000

Vocabulary:

Another phrase that we can use to describe a number plane is a 'coordinate plane'. This is because we locate coordinates on the plane.

Question 2

Here is a coordinate plane.

  1. What object has coordinates $\left(6,2\right)$(6,2)?

    Dog

    A

    Apple

    B

    Star

    C

    Bike

    D

  2. Write the coordinates of the rabbit.

    $\left(\editable{},\editable{}\right)$(,)

 

Remember!
  • axes - the horizontal and vertical lines, the $x$x-axis and $y$y-axis
  • quadrants - the four different sections our axes create
  • coordinates - these tell us where points are located, with an $x$x-value and a $y$y-value
  • origin - where both $x$x and $y$y are equal to $0$0 and it's where both axes meet

 

Outcomes

5.G.A.1

Use a pair of perpendicular number lines, called axes, to define a coordinate system, with the intersection of the lines (the origin) arranged to coincide with the 0 on each line and a given point in the plane located by using an ordered pair of numbers, called its coordinates. Understand that the first number indicates how far to travel from the origin in the direction of one axis, and the second number indicates how far to travel in the direction of the second axis, with the convention that the names of the two axes and the coordinates correspond (e.g. x-axis and x-coordinate, y-axis and y-coordinate).
