Use the number below to answer the given questions: 8, ) What is the value of the 3? A 30 B 3 C 0.3 D ) What is the value of the 9? A 900 B 90 C 0.9 D ) Write down how you would say this number?

 You and a friend decide to ride your bike to the Belgique chocolate shop in the center of Kent.

 As you are getting ready, your friend wonders if you are even able to ride that far.

 Even if you can ride that far, can you make it back?

 How far do you think you could ride in a day?  How do you think your speed would change throughout the course of the day?  What conditions might affect the speed and distance you can ride that day?

 How could you test endurance and ‘condition variation’ to see how far you could ride in a day?

Bouncing ball activity

 How did our numbers appear to change?  What are some things that might cause the number of bounces to vary from person to person?  What similarities/differences did you notice on each other’s graphs?

How do we say this point?

How do we write this point?

(G, 6)

How do we say this point?

How do we write this point?

(7,3)

The point is always labeled (x,y) (7,3)

The point is always labeled (x,y) Remember: X is the horizontal value (7,3)

The point is always labeled (x,y) Remember: X is the horizontal value And Y is the vertical value (7,3)

The independent variable is ALWAYS on the x-axis The dependent variable is ALWAYS on the y-axis

The independent variable is ALWAYS on the x-axis The dependent variable is ALWAYS on the y-axis But why?

The Y value depends on what the X value is. Therefore we say Y depends on X.

The X value is whatever we say it is. Therefore we say X is independent.

 Using your worksheet, can anyone think of anything that is almost always independent? Dependent?

Please get out your bouncing ball data from last class

4 steps to creating a graph

1. Identify the variables. (find out what you are comparing)

4 steps to creating a graph 1. Identify the variables. (find out what you are comparing) 2. Decide which is dependent and independent. (find out which axis the variables belong to)

 Work alone on page 9 A,B,C  When you are done, raise your hand

 How does a graph display data differently than a table?  Give me 9 vocabulary words and their definition.  How would making the x-axis have a greatest value of 240 seconds and the y-axis have a greatest value of 300 bounces change the look of your graph?
