Standard: 4.4 - Data Analysis, Probability, and Discrete Mathematics

 

Strand: B - Probability

 

Cumulative Progress Indicator: 2 -   The student will provide probability of specific outcomes

·        Probability of getting specific outcome when coin is tossed, when die is rolled, when spinner is spun (e.g., if spinner has five equal sectors, then probability of getting a particular sector is one out of five)

·        When picking a marble from a bag with three red marbles and four blue marbles, the probability of getting a red marble is three out of seven

 

Grade: 2

 

Sample Activities:

 

·        Children roll a die ten times and record the number of times each number comes up. They combine their tallies and discuss the class results.

 

·        Children predict how often heads and tales come up when a coin is tossed. They toss a coin ten times and tally the number of heads and tails. Are there the same number of heads and tails? They combine their tallies and compare their class results with their predictions. (See Making Sense of Data, in the Addenda Series, by Mary Lindquist.)
