Unit 4: Day 7
Tasks
46.1 Boolean Quick Check #4 (same difficulty level as #3)
- Be sure to remind them that capitals do matter
- A copy can be found in the Resources folder 1.4 - Year 1: Programming Part 2
- Or you can see a student version of the quiz here.
46.2 Marvel Character Guesser Example
- Review/discuss the use of Boolean Variables.
- use a sceneNum variable to change questions, just like in yesterday’s slideshow example.
- This is one of the longest examples we do. I STRONGLY suggest giving them at least half the code to start.
- It is also the leaping off point for the next assignment. For that assignment, students continue this example by adding more characters and thus demonstrating they understand the logic.
- To make it easier for you to read, all the code is on the next page.
- New: Introduce the concept of ‘passing in a parameter’ by adding a variable that will control the red value of the color of the text in each function. Truly, this is not necessary but the idea of Argument/Parameter passing is an important concept so introducing it subtly is helpful. Parameters are variables used to pass data INTO a function to help it do its job.
-
Discuss the following AP Knowledge statements about functions (aka procedures)
- AAP3.A.1- A procedure is a named group of programming instructions that may have parameters and return values.
- AAP3.A.2 - Procedures are referred to by different names, such as method or function, depending on the programming language.
- AAP3.A.3 - Parameters are input variables of a procedure/function. Arguments specify the values of the parameters when a procedure is called.
- AAP4.A.1 - A procedure/function call interrupts the sequential execution of statements, causing the program to execute the statements within the procedure before continuing. Once the last statement in the procedure (or a return statement) has executed, flow of control is returned to the point immediately following where the procedure was called
- AP-3.B.5 Using parameters allows procedures to be generalized, enabling the procedures to be reused with a range of input values or arguments.
46.3 Assignment 3 - Marvel Characters Assignment
- Instructions for this assignment can be found in the folder: 1.4 - Year 1: Programming Part 2
- This assignment is an extension of the example. The example code is provided at the end of the instructions doc for those that missed it.
