Abstract Thinking: 3-D Views, Shape Flips & Hidden Patterns
Student Name
Date
Learning Objective
Solve problems using 3-D viewpoints (top, front, side), identify how shapes change after flips, turns, folds, and rotations, and discover hidden or missing parts in incomplete shapes.
Section 1 — What do you already know?
Before we begin, write down anything you already know about: 3-D Views & Shape Transformations
Section 2 — Key Concepts
1. What is abstract thinking in Class 3 computational thinking?
Answer:
Abstract thinking is the ability to imagine and solve problems with hidden, unseen, or transformed ideas without needing physical objects in front of you — such as visualising the top of a building, or imagining what a shape looks like after a flip.
2. How do different viewpoints of 3-D objects work?
Answer:
Every 3-D object looks different depending on where you look from. For example, a cylinder looks like a circle from the top view, but looks like a rectangle from the front or side view.
3. What happens to a shape during flips, turns, and folds?
Answer:
A flip creates a mirror reflection across a line of symmetry. A turn (rotation) spins the shape around a point (like hands of a clock). A fold checks if two halves match up along a crease line.
Section 3 — Check Your Understanding
Answer the following questions in your own words.
1. Identify front, top, and side viewpoints of 3-D objects like cubes, cylinders, cones, and buildings
2. Predict and trace how shapes look after mirror flips (reflections), quarter/half turns, folds, and rotations
3. Spot hidden, missing, or overlapping pieces in incomplete shapes and grid patterns
4. Connect spatial reasoning to how computers represent 3-D graphics and game worlds
Section 4 — Fill in the Blanks
Complete the sentences using the concepts you have learned.
1. 3-D Views & Shape Transformations helps computers _________________ patterns from _________________.
2. The main difference between AI and a normal program is that AI _________________ from data rather than following fixed _________________.
3. One real-world example of 3-D Views & Shape Transformations is _________________, which uses it to _________________.
4. The inputs used by an AI model are called _________________ and the output it predicts is called a _________________.
Section 5 — Scenario Thinking
🤔 Think about this:
A healthcare organisation wants to use 3-D Views & Shape Transformations to assist doctors in diagnosing patients earlier. What data would the AI need? What challenges could arise? How can the team ensure the AI is fair, safe, and accurate?
Section 6 — What Did I Learn?
✅ Three key ideas I now understand:
❓ One question I still have:
⭐ Challenge Task
If you were designing an AI solution using 3-D Views & Shape Transformations, what problem would you solve? Outline a 3-step plan: (1) Problem statement, (2) Data to collect, (3) How to verify accuracy.
