Algorithmic Thinking: Step-by-Step Rules, Grid Paths & Sequences
Student Name
Date
Learning Objective
Follow and write step-by-step algorithms: number sequence rules (+, -, ×), grid navigation paths, before/after event sequencing, and multi-step transfer instructions.
Section 1 — What do you already know?
Before we begin, write down anything you already know about: Grid Paths & Step-by-Step Rules
Section 2 — Key Concepts
1. What is algorithmic thinking for Class 3 students?
Answer:
Algorithmic thinking is the skill of creating or following a precise, ordered sequence of instructions to reach a goal or solve a puzzle without guessing.
2. How does grid navigation work in algorithmic thinking?
Answer:
A grid is like a map with squares. An algorithm gives exact step-by-step movement commands (e.g. 'Forward 2, Turn Right, Forward 3') to navigate from start to finish while avoiding obstacles.
3. How do before, after, and in-between clues work?
Answer:
These are sequencing clues that tell you the order of events. For example, if 'Breakfast is before Lunch' and 'Recess is in-between Breakfast and Lunch', the algorithm orders them: Breakfast → Recess → Lunch.
Section 3 — Check Your Understanding
Answer the following questions in your own words.
1. Follow and design clear step-by-step rules for arithmetic and geometric sequences
2. Navigate grid paths using directional instructions (Forward, Backward, Turn Left/Right)
3. Order events chronologically using before, after, and in-between clues
4. Track values that increase or decrease across multiple sequential steps
5. Trace and debug multi-step instructions when a path or transfer rule goes wrong
Section 4 — Fill in the Blanks
Complete the sentences using the concepts you have learned.
1. Grid Paths & Step-by-Step Rules 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 Grid Paths & Step-by-Step Rules 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 Grid Paths & Step-by-Step Rules 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 Grid Paths & Step-by-Step Rules, what problem would you solve? Outline a 3-step plan: (1) Problem statement, (2) Data to collect, (3) How to verify accuracy.
