Randomness Exploring Computer Science Lesson 4-10 – Part 2

Objectives The students will be able to: Use a random number generator to write a dice program.

Journal What does the word random mean in English? Write down the questions. Answer with complete thoughts and sentences or you will not receive full credit on your journal

Randomness if I roll a pair of dice, will the numbers come out in order (2, then 3, then 4 the next roll, etc.)

Randomness This unpredictability is called randomness. Randomness can make games more exciting. For example, how many spaces will I get to move this turn? Randomness is also used in computer science for simulations and in scientific/statistical experiments.

Getting a Random Number in Scratch pick random is under operations

Let’s Look at a Program… This is the start of a program… What do you think it does?

Finish the Program… Download dice.sb from the website. Finish the dice program so it works completely and then add a second die. You can duplicate the sprite but they need to work separately! See is you can figure out how to hide the variables from the screen.
