Lesson 4 verical and horizontal graphs

transcript

Entry Activity

We are going to pay a game called Taboo.

I am going to describe a key word (without using

it) and you need to write down what it is!

Key WordsCo-ordinate, Horizontal,

Vertical, x axis, y axis,

Equation

Get ready to write down your key word

Word number 1• It is straight• It is top to bottom• It is vertical• It is on all algebraic graphs• It can go on forever if needed• It is how we describe the line that goes on a graph

to show the scale

Word number 2• It is has two values• The values can be positive or negative• It describes a position• It is used when working on graphs• It is used in everyday life when using maps• It has a value of x and a value of y• (x,y)

Word number 3• It is across• It is left to right• It is the same direction as the x axis• It is from the word horizon

Word number 4• It is across• It is left to right• It is horizontal• It is on all algebraic graphs• It can go on forever if needed• It is how we describe the line that goes on a graph

to show the scale

Word number 5• It is straight• It is how we describe the y axis• It is the name of some blinds (that go on windows)• It is up and down• If we dropped a ball it is the way it would go

Word number 6• It has letters or symbols to represent unknown

numbers• It and can have numbers in it• It is how we write rules in Maths• You can put different number in it• It can have lots of different outcomes• It can be used to describe a line

Today I will learn to identify the equation of vertical and horizontal line graphs Level 5

Challenge Objective: Solve problems using vertical and horizontal line graphs Level 5+

Key WordsCo-ordinate, Horizontal, Vertical, x axis, y

axis, Equation

•All will find the equation of a horizontal straight line•Most will find the equation of a vertical straight line•Some will solve problems using the above

Plot the following points on the axes:(5, 0) (5, 1) (5, 2) (5, 3) (5, 4)Join up the points with a straight line

(0, 4) (1, 4) (2, 4) (3, 4) (4, 4) Join up the points with a straight lineWhat do you notice?

Let’s check you understand...

Using your planners show me how you found this
