Mathematics, level: Elementary
Posted Sat Nov 17 14:10:15 PST 2001 by laura Provenza (lprov800@hotmail.co).
New York
Materials Required: pictures representing each type of graph, drawing paper, crayons, rainbow chip cookies
Activity Time: 40-45 minutes
Concepts Taught: Pie Graphs, Line Graphs, Pictographs, and Bar Graphs

Aim: The students will be able to differentiate between bar graphs, line graphs, pictographs and bar graphs.

Behavioral Objectives: After participating in a hands-on cookie activity, the students will be able to label and draw their own graphs.

Plan:
Content:
(1) Graphs are used to show and compare data or facts. It is a way of presenting information in an organized manner.
(2) A bar graph represents data in bars. A bar graph may be constructed horizontally or vertically. They are usually used to compare data.
(3) A pictograph represents data in pictures.
(4) A line graph represents data in lines. They are usually used to show change.
(5) A pie graph represents data in a circular form. The pie is divided in different portions.

Procedure:
Introduction:
I will begin the review lesson by asking the students to define the term graph and tell what they are used for. I will then ask them to name the four different graphs they learned. I will ask them to explain how each graph represents data. I will then have a display of all four graphs that they learned representing the same information, refreshing their memories of what they all look like.

Guided Practice:
I will hand out worksheets reviewing how to read different graphs

Follow-up Activity:
I will create an interactive bulletin board on the data of the class's favorite subjects. The class will participate and then answer several questions on the results of the graph.

Group Work:
I will hand out drawing paper, crayons and rainbow chip cookies to the class. The children will be working in groups. Each child will receive a cookie and each group will receive one sheet of drawing paper and different color crayons. Each group is to construct their own graph representing the total number of different color chips they have.

Independent practice:
Homework worksheet on constructing the four different graphs with the given data.

Closure:
I will end the lesson by calling on the children to share their group work with the rest of the class.

Materials:
-pictures representing each type of graph
-drawing paper
-crayons
