Dynamite Data

Jennifer CatlettBay District Schools

Description

The students will collect and organize data for tally charts, tables, and pie graphs.

Objectives

The student solves problems by generating, collecting, organizing, displaying, and analyzing data using histograms, bar graphs, circle graphs, line graphs, pictographs, and charts.

Materials

-Internet access
-Interactive Student Web Lesson (see Weblinks)
-Unifix Cubes
-Coins
-Paper, pencils
-Math Journals

Preparations

1. Get materials together and organized.
2. Prepare task cards as suggested in the lesson.
3. Check the Internet stations to verify connectivity and preview the student online lessons.

Procedures

The student will collect responses and display data in a table and bar graph.
NOTE: Prior to teaching this lesson the children should be familiar with the different parts of a graph (titles, labels, key...).
Gain attention by telling students: We can use graphs to chart data (information). Let's collect data and graph it together. Raise your hand if you like candy? What is your favorite candy? (List at least 5 different kinds on the board. Have the whole class vote once. Use tally marks to record votes.)

Tell students: If your mom or dad asked you what you wanted for dinner and they gave you the following choices what would you choose? (List the following choices: pizza, hamburgers, hotdogs, tacos).

Procedures:
1. Now ask students to vote on one of the following choices.

2. Record their answers on the board using a tally chart.

3. Transfer the tally chart information into a table.

4. Transfer the table into a bar graph, then a line graph. Note: Assist students as necessary.

5. Discuss terms: data, votes, tally charts, tables, and bar graph. Note: You may want the students to write the terms in their Math Journals.

6. Replace the above voting choices with colors (yellow, blue, red, or green). Allow students in the class

Group Work:
Divide the students into five groups for centers. Try to rotate the groups every 10-15 minutes.

Center #1 Beacon Learning Center
Lesson: Piece of Pie (See Weblinks)

Center #2 Organizing Data
Materials: Unifix Cubes, paper, pencils
Task: Direct the students to organize the cubes by color and record their findings onto a tally chart. Next, have students create a table and record their findings. Finally, ask the students to create a bar graph using the collected data.
Note: Remind students to group tally marks by 5s and to draw the fifth tally mark across the first four.

Center #3 Organizing Coins
Materials: coins, paper, pencils
Task: Have the students count the amount of each coin and record their findings onto a tally chart. Next, have to students create a table and record their findings. Finally, ask the students to create a bar graph using the collected data.
Note: Remind students to group tally marks by 5s and to draw the fifth tally mark across the first four.

Center #4 Organizing Buttons
Materials: buttons, paper, pencils
Task: Have the students sort the buttons and record their findings onto a tally chart. (Example: group by color, size, shape...) Next, have to students create a table and record their findings. Finally, ask the students to create a bar graph using the collected data.
Note: Remind students to group tally marks by 5s and to draw the fifth tally mark across the first four..

Center #5 Unique Group Characteristics
Materials: children, paper, pencils
Have the children decide on at least four categories to collect information for and chart. (Example: color of eyes, shorts/pants, girls/boys, hair color...)
Next, have to students create a table and record their findings. Finally, ask the students to create a bar graph using the collected data.
Note: Remind students to group tally marks by 5s and to draw the fifth tally mark across the first four.

Wrap-up:

2. Discuss what they know about collecting and organizing data.

3. Discuss recording larger amounts of data (Example: 1 tally mark represents 5 votes).

4. Discuss the Unique Group Characteristics (Center #5) findings with the whole group.

5. Choose four categories and chart the results on the board. Note: Try to include one category from each group's collected data. (Example: hair color; boy/girl...)

6. Create a tally chart, table, and bar graph using the data gathered.

7. Review terms: data, tally chart, tables, and bar graphs

8. Discuss interesting data to collect from their families. (Examples: favorite vacation place, restaurants, activities, so on...)

9. Homework: Decide on at least 3 categories, as a class, and have each student collect that data from their family as homework. (Suggestions: eye color, hair color, number of children...)
NOTE: The data can be used the following day to graph on poster board for the classroom.

Assessments

Formative Assessment

The assessment for this lesson will be teacher observation of students as they create graphs to solve problems. Anecdotal notes will be taken on each student as the teacher circulates and assists with the graphing in progress.
Observe the student gathering data, making tally marks and graphing data.
Verbal Discussion- Discuss terms and check for understanding by graphing data together as a whole group.

Allow the groups explain their completed bar graphs from Center #5.
NOTE: Prior to teaching this lesson the children should be familiar with the different parts of a graph (titles, labels, key...).
