NETS Lesson Plan

Grade Level: 6th

Subject: Ratios and Statistics

Objectives: Students will be able to

    Generate ratios based on experiment
  
    Generate statistics based on experiment

    Graph and explain information recorded during experiment

    Use technology to generate graphs and exhibit information

Materials:

    Pair of dice

    Computer access

Math Standards:

6.3.A Identify and write ratios as comparisons of part-to-part and part-to-whole relationships

6.3.B Write ratios to represent a variety of rates.

6.3.C Represent percents visually and numerically, and convert between the fractional, decimal, and percent representations of a number.

6.3.F Determine the experimental probability of a simple event using data collected in an experiment.

6.3.G Determine the theoretical probability of an event and its complement and represent the probability as a fraction or decimal from 0 to 1 or as a percent from 0 to 100.

NETS Standards

1. Creativity and Innovation

    d. Identify trends and forecast possibilities.

    This standard applies to my lesson through the use of graphing trends and interpreting the data from experiments to forecast possibilities. The students will be using different mediums in order to     meet this standard.

3. Research and Information Fluency

    d. Process data and report results.

    This standard applies to my lesson through the use of graphing trends and interpreting the data from experiments to forecast possibilities. The students will be using different mediums in order to     meet this standard.

5. Digital Citizenship

    a. Advocate and practice safe, legal, and responsible use of information and technology.

    b. Exhibit a positive attitude toward using technology that supports collaboration, learning, and productivity.

    This standard applies to my lesson through teh use of computers and the access to the internet by students. They are required to use professionalism and responsibility while using the technology.

Anticipatory Set: We have been working with numbers and how they relate to each other in the form of ratio. Today we ill be working on predicting the outcome of random statistics through t hte use of ratios.

Engage: Have you ever played Yahtzee? Remember rolling the dice and hoping for a certain number to come up?

Pass out the pairs of dice to all of the groups.

Explore: Everyone roll the dice. How many ones came up? How many sixes? Now roll the dice 3 times. Did the same numbers come up every time?

Explain: Students will

1. Roll the dice 20 times.
2. Record the result of each roll.
3. Recod in a table the number times each number came up in the rolls.
4. Work together to produce a ratio of numbers to rolls.
5. Produce a chart graphing the results.
6. Students will roll the dice a random number of times and produce graphs to chart the results.

Questions:

    How likely is it to get a number that you want on each roll?
    Do any numbers seem to come up more often than others?

Elaborate: Have students discover and exhibit different ways of producing ratios for prediction. Have students research how companies use ratios and probabilities in order to determine the course of their buinsess transactions.

Evaluation: Students will be evaluated based on the graphs produced for the experiment results.

Assessment: Students will be able to produce ratios and graphs based on data.
