(312) 535-9015Objectives:

This lesson can be easily adapted for all grade levels. Upon completion of

this lesson, the students will be able to do the following:

-Use a ruler and measure accurately to the nearest inch.

-Draw and label properly different graphs (line, pie, bar, pictograph)

-Estimate/record measurement on number line using intervals.

-Collect data and analyzeMaterials:

-Tape measures

-ribbon (one per child)

-post-its (two per child)

-scissorsStrategy:

Students work with a partner for this activity. You may want to have tape

measures already pretaped to a wall. Some taped in a horizontal fashion to help

assist measurement in arm span. Others taped in a vertical manner to assist the

measurement of height.

-One student measures his/her partners arm span (finger tip to finger tip).

-Record this information on a post it.

-Measure partners height. Record information on same post-it.

-Cut a piece of ribbon to the height of partner.

-Use second post-it and record height only in large print.

-Switch roles of partners.

-After students are finished with measurements, students are to hang their

ribbon on the wall according to height. The ribbons should hang from smallest

to largest. Students should also identify their ribbon with their post-it

that states their height in large print. (You may want to have cards with

measurements already established in intervals of six inches to help assist

students in finding "their" place on the classroom number line).

-When all students are finished, the teacher can help students use the

information to graph.

-Demonstrate to students that all graphs need a title and x and y axes.

Graphing

Bar graph

(Use graph paper on overhead) Have students suggest title for graph. Now fill

in information on x axis (height). Write in measurements from smallest to

largest. The y axis will represent the number of people. Show students how to

fill in bar graph as they complete a copy at their seat.

Pictograph

Create title and the x and y axis with the students.

Have students draw a long rectangle, square, or short rectangle on their post-

it (the one with arm span and height measurements). This shape should represent

their body shape.

Long rectangle height > arm span

Perfect square height = arm span

Short rectangle height < arm span

Call students up by rows to place their post-its on the pictograph according to

body shape.

Pie graph

Remind students that a pie graph represents the class as a whole, each section

represents one student. Have a pie graph already sectioned according to the

number of students in the class. Color code body shapes with a color chart.

Example: perfect square = blue

long rectangle = red

short rectangle= yellow

Have a student come up and color the pie graph accordingly.

You may want to glue this circular graph onto a large sheet of paper and

write all of the necessary information on the sheet (title, color code).

Performance Assessment:

Students would decide what topics, ideas they would like to graph in class.

(Types of pets owned, favorite tv show, sport, game, etc, number of siblings.)

Students can break into pairs and interview or write a short questionaire for

their classmates to complete. Students would have a time frame to gather

information and then come up with a graph that would best portray the

information gathered. Students would need to decide what type of graph would

best meet their needs. Display graphs around the room and discuss information.

Enhancement:

Ask students how you sectioned off the pie graph so that each section has the

same size. Introduce a protractor and the measurement of a circle is

360 degrees. Give students a paper plate and protractor and have them work in

groups of 5. Tell them to evenly divide the paper plate into 5 equal pieces and

draw their favorite pizza topping on their section.
