# Activity: Rock, paper, scissors
|
|||
|
|
|
|||
|
|
For this activity, each student will need a micro:bit.
|
|||
|
|
Everyone will create the same program, the classic rock paper scissor game.
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
## Introduce activity
|
|||
|
|
* Have students recall the classic rock paper scissors game.
|
|||
|
|
* What are the rules of the game? What are the conditionals?
|
|||
|
|
>Example: If Player A gets rock, and Player B gets scissors, Then Player A wins.
|
|||
|
|
* Have students write the pseudocode for how to play the game on the micro:bit.
|
|||
|
|
>Example pseudocode:<br/>
|
|||
|
|
On button A press: choose random number from 0-2
|
|||
|
|
If random number = 0, then display rock icon,
|
|||
|
|
Else if random number = 1, then display paper icon,
|
|||
|
|
Else display scissors icon.
|
|||
|
|
* Point out that because there are only three possibilities, we don’t need to do a separate check to see if random number = 2. So we just use an else.
|
|||
|
|
|
|||
|
|
## micro:bit
|
|||
|
|
* Working from the specifications, have students work in pairs to try to code a Rock Paper Scissors game on their own.
|
|||
|
|
* If students get stuck, there is a tutorial at https://pxt.microbit.org/projects/rock-paper-scissors (steps 1 through 4), that leads students step-by-step through the process of coding a working rock paper scissor game for their micro:bit.
|
|||
|
|
* Let them play the game against their program.
|
|||
|
|
|
|||
|
|
## Ideas for Mods
|
|||
|
|
* Add a way to keep score: Steps 5 through 7 in the tutorial
|
|||
|
|
* Mod the game to use different images or to add more options like ‘Rock Paper Scissors Lizard Spock’, Step 8 in the tutorial
