Introduction

This capstone pulls together everything in Coding Fundamentals: what code is, algorithms, variables, logic, loops, functions, conditions, and block coding. You will design a tiny but complete program—not a sprawling mega-game. Done means planned, built, tested, and explained.

Choose tools your class supports (Scratch/Blockly or beginner text). Pair the build with steady keyboard habits on TYPE10X Practice so naming variables and typing answers stays smooth. Ready to ship your first real coding artifact?

Learning Objectives

By the end of this lesson, you will be able to:

Select a scoped project idea that fits beginner skills
Write a short algorithm and variable list before building
Implement core features with loops and conditions
Test edge cases and fix at least two bugs
Present your project and map features to coding concepts

Main Lesson

Project menu (pick one)

Choose one path. Keep scope tiny.

Project	Core features	Concepts practiced
A. Quiz Game	5 questions, score, pass/fail message	variables, loops, conditions
B. Click / Collect Game	Move player, collect 5 items, win screen	events, loops, collisions, score
C. Pet Simulator	Feed/play buttons, hunger/energy vars, status	variables, functions, conditions
D. Shortcut Trainer	Show prompt, check typed answer, accuracy	input, conditions, counters

All four are valid. Teachers may assign one for the whole class.

The build pipeline

Use this sequence every time:

Goal sentence — One line: “Players answer five math questions and see a final score.”
Success checklist — 4–6 must-have features (not wishes)
Algorithm / flowchart — Ordered plan with decisions
Variable table — Names, types, starting values
Function list — Reusable actions you will define
Build vertical slice — One question or one collectible working end-to-end
Expand — Add remaining items via loops where possible
Test + debug — Trace edge cases
Polish — Messages, instructions, win/lose clarity
Present + reflect — Teach others how it works

Skipping planning usually creates stuck projects. Algorithms first—same rule as Lesson 2.

Feature checklist template

Copy and customize:

[ ] Program starts from a clear event (flag / run / button)
[ ] At least one variable updates correctly
[ ] At least one loop (or repeated ask pattern)
[ ] At least one IF/ELSE decision with feedback
[ ] At least one function or custom block (recommended)
[ ] Win/lose or done state is obvious
[ ] Short on-screen instructions for a new user

Suggested architecture (Quiz Game example)

Variables

Name	Type	Start
`score`	number	0
`questionNumber`	number	1
`answer`	text	""

Functions

askQuestion(prompt, correct) → returns true/false; updates score
showResult() → prints pass/fail using conditions

Main algorithm

```text

SET score TO 0

FOR questionNumber FROM 1 TO 5 DO

CALL askQuestion(...)

END FOR

CALL showResult()

```

That skeleton is enough. Art and sound are optional spice, not the meal.

Testing plan (do not skip)

Test	What you try	Expected
Happy path	Correct answers / successful play	Score rises; win message
Wrong path	Incorrect answers	Feedback; score fair
Edge	Barely-passing score threshold	Correct category message
Replay	Run twice	Values reset properly
Instructions	Hand to a classmate cold	They know what to do

Write bugs in a list: symptom → cause → fix. Debugging is part of the grade of a real coder’s day.

Documentation mini-sheet

Include on a one-pager or README comment:

Project title and goal
How to run/play (3 steps)
Variable list
Where loops/conditions/functions appear
One bug you fixed and how

This proves understanding—not only that something moved on screen.

Presentation (60–90 seconds)

Structure:

Goal (1 sentence)
Demo (30–45 seconds)
“Under the hood” concept map (variables/loops/conditions)
What you would add next if you had another hour

Confidence grows when you connect features to Vocabulary from earlier lessons.

Key Definitions

Capstone / mini project — A small complete build applying multiple skills.
Scope — The intentional limits of what you will and will not include.
Vertical slice — A thin end-to-end feature working early.
Acceptance checklist — Must-have features that define “done.”
Regression — When a fix breaks something that used to work.
Reset — Returning variables to starting values for a new run.
User instructions — On-screen guidance for first-time players.
Demo — A live walk-through of the working project.
Reflection — Notes on what worked, what was hard, what is next.
Portfolio piece — A saved project you can show teachers or clubs.

Examples

Example 1: Quiz done definition

Five questions via a loop, score variable, pass at >= 4, custom askQuestion block—shipped.

Example 2: Collect game done definition

Player moves with arrows; five coins; score display; touching coin hides it and adds points; score 5 shows win.

Example 3: Pet sim done definition

Buttons call feed and play; status function reports state; if hunger hits 0, show emergency message.

Example 4: Bug story

Score kept rising after replay because reset was missing. Fix: set score ← 0 on green flag before the loop.

Real-World Scenarios

Scenario A — Scope creep

Leila planned a quiz, then tried cutscenes, multiplayer, and 3D. She cut back to five questions and finished—scope discipline won.

Scenario B — Pair programming

One student drives the editor; the other traces the algorithm and test cases. They swap roles halfway.

Scenario C — Showcase night

Families understand the project when students explain “this IF checks the answer; this loop asks five times,” not only “look at my sprite.”

Tips

Tip: Build the scoring path before decorating sprites.

Tip: Save project-v1, project-v2 before risky rewrites.

Tip: If stuck over 10 minutes, return to the paper algorithm and trace.

Warnings

Warning: Starting over repeatedly without saving versions loses working progress.

Warning: Copying an entire online project and claiming it as yours violates academic honesty—use tutorials as teachers allow, then make it yours with understanding.

Did You Know

Did you know: Many famous games began as tiny prototypes that only proved one mechanic worked.

Did you know: Employers and clubs often care that you can explain your decisions—not that the art looks expensive.

Common Mistakes

No written goal or checklist
Too many features, zero finish line
Skipping reset of variables on restart
No user instructions
Cannot explain which block/line is the loop or condition

Interactive Exercise

Project Sprint Planning (20 minutes)

Fill this card before opening the editor:

Project choice (A–D or teacher assigned)
Goal sentence
Five checklist features
Variable table (minimum three)
One function name + job
Two test cases
Timebox: what you will finish today vs later

Teacher sign-off optional but powerful.

Practice Questions

Why does scope matter in a mini project?
What is a vertical slice?
Name three coding concepts your project must show.
Why test edge cases?
What belongs in a short project presentation?

Mini Challenge

Ship your chosen project to “checklist complete,” then perform a classmate handoff: they play with no help for two minutes while you only watch. Write three notes on confusing moments and improve instructions.

Summary

A beginner mini project is a complete, explained program that combines algorithms, variables, loops, conditions, and functions—built through planning, a vertical slice, testing, and presentation. Finishing small teaches more than dreaming big. You now have the foundations to keep creating, to attempt text coding with less fear, and to continue growing digital skills across the TYPE10X Academy.

Student Checklist

[ ] I chose a scoped project and wrote a goal sentence
[ ] I listed variables and an algorithm before heavy building
[ ] My project includes loop(s) and condition(s)
[ ] I tested happy path and at least one edge case
[ ] I can present how it works using coding vocabulary
[ ] I saved a portfolio version of my project

Teacher Notes

Provide a hard timebox and a shared rubric aligned to checklist features.
Offer mid-sprint “algorithm clinic” instead of only last-day rescue.
Celebrate bug-fix stories publicly to normalize debugging.
Optional gallery walk with sticky-note praise + one improvement.
Assess explanation quality equal to flashy media.

FAQ

Q: What if I cannot finish all features?

Ship the vertical slice and document what remains. A working core beats a broken epic.

Q: Blocks or text for the mini project?

Use what your class taught. Concepts matter more than syntax brand.

Q: Can I work with a partner?

Follow teacher rules. If paired, both must be able to explain every core part.

Q: How do I reset scores properly?

On start/event, assign initial values before loops or gameplay begin.

Q: What should I do after this lesson?

Review any weak lessons, complete quizzes for XP, take the Coding Fundamentals track assessment when unlocked, and keep building—plus maintain typing fitness on practice.
