Graphing day one

Objective:

I can formulate and answer questions by interpreting and analyzing displays of data, including multi-bar graphs or

double line graphs.

.

There are many different types of graphs.

pie graph/ circle graph

bar graph - single or double

frequency tables

venn diagrams

Tally charts

line graphs

TRY TO LIST AS MANY AS YOU CAN ON YOUR SLATES

DID YOU HAVE ANY MORE??

Back to the basics - tally charts

HOW MANY STUDENTS

HAVE FRECKLES?

4!HOW MANY

STUDENTS DO NOT HAVE FRECKLES?

8!

Vocabulary

The new thing you need to know about tally charts it the

word frequency

FREQUENCY IS SIMPLY CHANGING THE TALLIES TO A NUMBER

THIS NUMBER CAN THEN BE USED TO MAKE MANY DIFFERENT TYPES

OF GRAPHS

Bar graphs

WHAT CAN you TELL ME ABOUT

THIS BAR GRAPH??

I have the kids come up and write in what they know on the lines
