Class plan.png What are we going to learn today?[edit]

Hello Class!

  • We will review the parking ticket problem
    • Two or three students will share their solutions with the class
  • We will discuss two basic computational idea: evaluating conditionals and understanding decisions
    • We will write a "guess that number game"
Please write a simple game that randomly selects a number between 0 and 100. A player must guess the number. Your program should tell the player if their guess is higher or lower than the secret number.

* Your program must generate a random number between 0 and 100 and assign that random number to a variable.
* Your program must ask the player to guess a number
* Your program must compare the players guess and the secret number. 
* The program should tell the player if their guess is:
** Much higher or much lower OR a little higher or a little lower than the secret number
* Your program must tell the player if they have won

Target.png How am I being assessed today?[edit]

I will assess you formatively today, and make a professional judgement to what extent you understand our learning material. I will use observation, your written work, answers to questions, and contribution to class discussions as datum to make my decisions. I normally record my observations in a "evidence of learning" spreadsheet, which I will happily share with you privately if you so wish. I usually need a day or two notice.
