Random Part 2

Summary

AAP-3.E For generating random values:
- a. Write expressions to generate possible values. 2.B
- b. Evaluate expressions to determine the possible results 4.B
AAP-3.F For simulations:
- a. Explain how computers can be used to represent real-world phenomena or outcomes 1.A.
- b. Compare simulations with real-world contexts. 1.D

AAP-3.E.1 The exam reference sheet provides Text: RANDOM(a, b) Block: RANDOM a, b which generates and returns a random integer from a to b, inclusive. Each result is equally likely to occur. For example, RANDOM(1, 3) could return 1, 2, or 3.
AAP-3.E.2 Using random number generation in a program means each execution may produce a different result.
AAP-3.F.3 Simulations often mimic real-world events with the purpose of drawing inferences, allowing investigation of a phenomenon without the constraints of the real world.
AAP-3.F.4 The process of developing an abstract simulation involves removing specific details or simplifying functionality.
AAP-3.F.5 Simulations can contain bias derived from the choices of real world elements that were included or excluded.
AAP-3.F.6 Simulations are most useful when real-world events are impractical for experiments (e.g., too big, too small, too fast, too slow, too expensive, or too dangerous).
AAP-3.F.7 Simulations facilitate the formulation and refinement of hypotheses related to the objects or phenomena under consideration.
AAP-3.F.8 Random number generators can be used to simulate the variability that exists in the real world.

Organize students into pairs.
You can use the Group Generator program to randomly sort students.
Distribute die or share random die roll generator with students.
Have students work in pairs to roll a die 30 times and record the results of each roll.
Collect data from each group.
Compare data of the entire class to the data of each small group.
Discuss the pattern that should eventually present itself with enough rolls (that a die roll has a 1/6 chance of landing on any given side).

Explain where you can find the random block in MakeCode Arcade.
Explain how it works.
Discuss the instruction and explanation of Random on the Exam Reference Sheet.
Direct students to Activity: Random Sprite Location.
Distribute the Tutorials on Randomness handout or direct students to find it in their OneNote notebook.
Instruct students to complete Tasks 1-3.
Remind students to publish their programs and add the link to their code on the handout.
Direct students to respond to the reflection questions on the page when they finish the tasks.
