### Lesson plan
#### Introduction
1. Explain today's session will be different mini-projects to develop skills in scripting
- Important to understand these concepts since adventure game will have more scripts.
- Point out these projects, like a trap, can be included in the adventure game project they'll start in Session 3.
#### Guided tutorial - Work with properties
1. Lead students through the following tutorials:
- [Object Properties](../../../tutorials/fundamentals/coding-1/object-properties.md)
- [Parents and Children](../../../tutorials/fundamentals/coding-1/parents-and-children.md)
2. Encourage students to troubleshoot independently if they have an error. To help, have them try:
- Redoing their last few steps.
- Asking a peer for help.
3. As students write code, check that students write comments that accurately describe the code.
- Not Specific: Runs code
- Improved: Changes color of PracticePart
#### Guided tutorial - Code a trap
1. Lead students through the following tutorials:
- [Code a function](../../../tutorials/fundamentals/coding-2/code-a-function.md)
- [Intro to if statements](../../../tutorials/fundamentals/coding-3/intro-to-if-statements.md)
- [Traps with if statements](../../../tutorials/fundamentals/coding-3/traps-with-if-statements.md)
2. When working with if statements, check that students indent code to look like code samples. This helps make the code more readable, which becomes important as scripts grow larger.
#### Wrap-up
1. Recap what students have created and vocabulary: **property**, **loop**, and **function**.
2. Point out in the next session, students will start a new project where they make an adventure game.
### Appendix
### Troubleshooting and classroom tips
- While coding, remind students to double-check their capitalization or ask a peer to check their work. Even one incorrect letter can cause an error in longer words like `FindFirstChildWhichIsA`.
- Try the following below to help students develop troubleshooting skills.
- Purposely make a mistake in your code and ask students to identify the error. This can be easily turned into a game.
- Write a partial line of code and ask students to complete it.
- Utilize 'Ask 3 Before Me' where students ask three peers before asking the teacher for help. It's important for students to become comfortable independently troubleshooting as they advance to more complex projects.
