Ch3 Graphs

To get to the right level for the test,

you need to know many things about graphs.

This LessonUp helps you with it.

Next slide ....

shows you another opinion of Studying.

I don't agree with it, by the way!

STUDY:  all the LEARNING GOALS   from p.112 -117, in silence.

That is the SUMMARY of Ch 4.

You get 7 minutes time for this.

Write down things you don't understand,

so you can ask them afterwards!

Question 1:

QUESTION (from p.114):

In what different parts can a graph be divided?

When is it NOT allowed to use a ZIGZAG in your graph ?

Think about the kind of graph this is about.

graph number 1:

1. straight lines

2.equal steps on the axes

 

possible mistakes:

3. the time on the vertical axis

4. drawing a zigzag (Why would 

    that be a mistake here?!) 

possible mistakes:
