Unit #2-09

Learning Outcome

At the end of this lesson, you will be able to:

• understand and use an if statement

Review

• sequential programs

• sequential flowcharts

Lesson

• all our programs so far have been linear

  • go over if-then flowchart (see below)

• go over "Boolean Expression" and "If ... Then" (see videos below)

• go over "Random Numbers"

  • in TypeScript:
    randomNumber = randint(0, 1) 

  • in Python:

from random import *

random_number = randint(0, 1)    # Pick a random number between 0 and 1.

Activity

• recreate my "Random Number" program

Daily Assignment

• click on provided link to create a new GitHub repo

  • call the repo: TEJ2O.1-Unit2-09

• review the Rock, Paper, Scissor game:

  • get in your pairs and write a Micro:Bit program that you can each load onto your Micro:Bits

    • when you shake the Micro:Bit it will pick a number between 0 - 2, but show the corresponding rock - paper - scissor icon and stays on screen for 5 seconds

    • if you won, hit the "A" button to add 1 to your score

    • if you hit "B" it will tell you your score

  • see demo app below

    • you CAN ONLY use if statements (NO if ... then ... else!)

Extra

• do the above assignment but in Python
