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

Homework.png What is our homework?[edit]

To help strengthen your learning from today's class, please review the following pages:

Please create logical rules for the following problem. You should consult our page on logical rules for help

Dagmara is making some tea. She has many types of teas (over 25 boxes), but we might categorize her tea into a few simple categories. The categories are: caffeinated, non-
caffeinated, herbal, simple, uncommon, and medicinal. One tea could belong to many categories.

Dagmara has some guests and asks if they want some tea. The guests reply "yes, we would like some tea". Dagmara considers the time of day, and prepares the tea for her guests. 
Considering one of her guests has hurt her leg, deduce the logical rules Dagmara uses to select tea for her guests.

Please return the homework assignment to me via google docs. I will post this assignment on classroom.

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.

  • Confidence in dealing with complexity
  • Persistence in working with difficult problems
  • Tolerance for ambiguity
  • The ability to deal with open-ended problems
  • The ability to communicate and work with others to achieve a common goal or solution
