The document discusses functions with parameters in programming. It introduces API (Application Programming Interface) as a collection of commands used to build applications. Functions can have parameters to customize their behavior, such as specifying the distance or angle for a move or turn. The lesson objectives are to use functions with parameters to complete drawing puzzles, design a personal monogram, and demonstrate knowledge through practice. Students are asked to read documentation on new commands to understand how to use them properly. The benefits of functions with parameters include controlling behavior, reusing solutions, flexibility, and experimenting with different inputs and outputs.
![L7: Activity 1 to 13 on Code.org
Design a personal monogram making use of
the commands you learned during the lesson
Share your image & Upload to D2L
Draw whatever you like!
The only requirements are:
• use at least 3 different colors
• use moveTo
Explore the documentation for any new
commands you see and use your skills as
both an artist and user of API
documentation to draw something of
your own choosing.
If in doubt: try to re-create

- 2. Recall from previous session Function: also known as method/procedure which is a set of commands that can be called again and over again. Benefits of Function? Define Function then Call the Function to Execute Define one function inside another function Function is a form of Abstraction finding one solution for multiple problems. Function use Top Down approach breaking down big problems to sub problems.

LESSON OBJECTIVES Students will: Learn to read App Lab’s API documentation Use functions that accept parameters in order to complete a series of drawing puzzles Design a personal monogram making use of the commands you learned during the lesson Activity: Demonstrate your knowledge in Practice L7: API & Functions with Parameter
- 4. Discussion Board on D2L What makes a Programmer? 1. Reading Documentation 2. Learn by seeing examples of a language 3. Professional programmers will frequently reference documentation while designing software 4. Learning habits of mind and patterns that allow you to use a language (including its documentation) effectively 5. Practice makes you a perfect programmer
- 5. L7: API & Functions with Parameter API (Application Programming Interface) is a collection of commands used to build applications. Functions have parameters which are information that customize and control the behavior of a function. For example, you can specify moveForward(103) to move the turtle exactly 103 pixels Library collection of functions with shared purpose. Documentation: A description of the behavior of a function Since parameter value can change, you will often see a written description for the command. Example: moveForward(distance), turnLeft(angle) - drawRectangle(sideLength, width).Code.org Code.org
- 6. L7: API & Functions with Parameter App Lab has documentation: look up documentation about the commands of the language penColor(), penWidth() dot(), arcLeft(), arcRight(), moveTo(), turnTo() Hexadecimal penColor(“#FF0099”) Students are asked read documentation about all the new commands.

- 8. Learning Objectives Identify situations for creating functions with parameters. Incorporate functions with parameters into an "Under the Sea" digital scene. Test functions with parameters using random input. L8: Creating Functions with Parameters Watch Video
- 9. L8: Creating Functions with Parameters What are the benefits of creating Functions with Parameters? 1. Control behavior of the function – Customize it for user needs. 2. Create complex drawings. 3. Can generalize solutions to problems instead of duplicating code. 4. Offers extra flexibility - removes the need to create multiple functions that do almost the same thing. – Remove repetition and patterns 5. Easily experiment with different inputs to see what kind of output we can produce. Watch Video D2L Discuss & Share
- 10. Defining multiple functions to draw different sized squares results in lots of repetitive functions . Any time you find yourself effectively copy and pasting large sections of code, it's usually a sign that there is a better way. L8: Creating Functions with Parameters
- 11. L8 Activity 1 to 14 on Code.org Modify the program that creates an “Under the Sea” scene by adding parameters to functions. Use the random number functions to supply random values to function calls so the scene looks a little different every time the program runs. Example: randomNumber(0,3) to randomize image so that every time your run program you get different scenes like below:
