Main Objective:

Students will collect, display and analyze data to make predictions about a population.

General Outcome:

Collect first- and second-hand data, display the results in more than one-way, and interpret the data to make predictions.

Specific Outcomes:

  1. Display the same data in more than one way.

  2. Make predictions and inferences when solving similar problems.

  3. Obtain new information by performing arithmetic operations on the data.

Activity/Lesson Ideas:

  1. Karen surveyed two Grade 3 classes to find out their favorite videos from the Glen Anaquod tipi raising videos. This is her tally chart.

    Have students complete and answer the following:

    • Complete the tally chart.

    • How many children did Karen survey?

    • How many children voted for the 2nd video? How many did not vote for the 2nd video? How are the two related?

    • Show the results of Karen’s survey on a bar graph.

    • Make a pictograph to show Karen’s information. Let one picture represent two votes.

    • Which graph do you think best shows Karen’s information? Explain your answer.

    • What five videos do you suppose would be the favorites in your class?

    • Predict your tally, if you surveyed your class with these five videos. Carry out the survey.

    • Did the tally chart match the prediction and why or why not.

  2. A local newspaper asked children to vote YES or No to the question:

    “Did you know that the game lacrosse originated from an Aboriginal game?

    YES: 39

    NO: 28

    Ask students the following:

    • How many children were asked for their opinion?

    • How many more children said yes than no?

    • If twice as many children had been asked, about how many would have said yes? No?

      Ask students to predict what peers in their class would say? Allow students some time to conduct a survey to check their predictions.

  3. Show students an image of a medicine wheel. The four quadrants of the medicine wheel all represent an aspect of health – physical, mental, emotional, and spiritual.

    Five friends wanted to see how well they were taking care of their physical life. So the five friends each recorded the number of minutes they spent playing sports in one week.

    Jen 80

    Dale 110

    Kendra 440

    Ben 190

    Leslie 70

    Ask students the following:

    • About how many minutes per day does each student spend playing sports?

    • What might Kendra say when she looks at the total time she spends playing sports by her four friends? Why?
