Algorithmic Thinking: Step-by-Step Rules, Grid Paths & Sequences
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.
About This Resource
Follow and write step-by-step algorithms: number sequence rules (+, -, ×), grid navigation paths, before/after event sequencing, and multi-step transfer instructions.
CBSE-aligned computational thinking resource suitable for Class 3 students covering algorithmic thinking and grid navigation.
What Students Will Learn
- Follow and design clear step-by-step rules for arithmetic and geometric sequences
- Navigate grid paths using directional instructions (Forward, Backward, Turn Left/Right)
- Order events chronologically using before, after, and in-between clues
- Track values that increase or decrease across multiple sequential steps
- Trace and debug multi-step instructions when a path or transfer rule goes wrong

Questions & Answers
What is algorithmic thinking for Class 3 students?
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.
How does grid navigation work in algorithmic thinking?
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.
How do before, after, and in-between clues work?
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.
Why do we track increasing and decreasing values across steps?
Tracking values across steps (like +5 points in step 1, -2 in step 2) teaches how computer variables and counters work during program execution.
