Module 4 Computational Thinking Across Subjects
Computational thinking is not coding. It is a set of thinking moves every subject already uses — breaking a problem down, spotting what repeats, keeping what matters, writing steps someone else can follow, checking a claim against evidence. Teachers practise each move on their own subject’s NCERT material, plan one co-taught period with a computer teacher, and then turn the same moves on a class results grid — which is exactly how the rest of this programme reads learning data.
By the end, teachers can…
- 1 Name the five thinking moves — decomposition, pattern recognition, abstraction, algorithmic thinking, reasoning from evidence — and give one example of each from their own subject’s NCERT chapters.
- 2 Redesign one existing classroom task so that students must do at least two of the moves explicitly, without any device.
- 3 Describe where CBSE places CT for Classes 3–5 (inside Mathematics and The World Around Us) and for Classes 6–8 (across subjects, with subject and computer teachers collaborating), and what that means for their own timetable.
- 4 Plan one 40-minute period co-taught with a computer teacher, with each teacher’s role written down.
- 5 Read a class results grid computationally: break it down by item and by student, spot a shared pattern, name the underlying concept, and state what evidence would confirm or disconfirm the reading.
- 6 Explain why the programme’s teach → assess → identify → diagnose loop is computational thinking applied to teaching.
Session plan — 2 hours
| Time | Activity | Format |
|---|---|---|
| 0:00 10 min | Opening: you already think this way Pairs describe how they marked forty notebooks last week or built the annual plan: split the work, notice what repeats, ignore what does not matter, follow a routine, check a hunch. Five moves, no jargon yet. | Discussion |
| 0:10 20 min | Five moves, in school words Decomposition, pattern recognition, abstraction, algorithmic thinking, reasoning from evidence — one NCERT example each, none on a computer. Where CBSE puts CT: inside Maths and The World Around Us for Classes 3–5; across subjects for Classes 6–8, with subject and computer teachers working together. What this is not: coding, or a new period on the timetable. | Input |
| 0:30 30 min | Subject stations Teachers sit by subject and work one activity on paper. Maths (Class 8, Linear Equations in One Variable): write the steps for solving 3x − 7 = 2x + 5 as instructions a classmate must follow blindly; swap; run the other group’s steps on 5(x − 2) = 3x + 4 and find where they break. Science (Class 10, Light — Reflection and Refraction): from the six object positions for a concave mirror, extract the pattern in image position, size and nature; then write the ray rules as the abstraction that produces every case. English (Class 6): decompose “write a formal letter to the principal” into its parts; from three sample letters, find what every good opening paragraph shares; write a five-step proof-reading routine a student can run alone. Social Science (Class 7): given rainfall and temperature tables for two towns, break “why do they grow different crops?” into sub-questions, keep the pattern that matters and discard what does not, and write the reasoning steps so a peer can check each one against the table. Classes 3–5 (Mathematics and The World Around Us): from a Class 4 number-pattern worksheet (2, 5, 8, 11 … and a hundred-square with every third number shaded), write the rule as steps a classmate can follow to find the 20th term; then sort twenty picture cards of things in the school compound twice, by two different rules, and write which rule made the sorting easier and why — worksheet steps a primary teacher can run in a normal period. | Group work |
| 1:00 10 min | Shareback: same moves, five stations Each subject group shows its activity in two minutes; the room names which of the five moves it exercised. The point lands: the vocabulary is shared, the content is not — which is what lets a subject teacher and a computer teacher plan together. | Discussion |
| 1:10 15 min | Planning one co-taught period Subject teacher + computer teacher pairs plan one 40-minute Class 6–8 period on the one-page planner: what the subject teacher teaches, what the computer teacher adds (a representation, a flowchart, an unplugged algorithm), what the students produce, and who assesses what. Primary teachers (Classes 3–5) plan the same 40 minutes as a single-teacher worksheet period in their own subject — CBSE places CT inside Mathematics and The World Around Us there, with no computer teacher needed. | Group work |
| 1:25 25 min | CT on a results grid A printed grid: 40 students × 10 items from a Class 8 diagnostic on linear equations, with the option each student chose. Groups decompose it by item and by student, find which wrong options cluster together, name the concept behind the cluster rather than the question numbers, write a triage routine (who, which concept, what first), and say what evidence would confirm or disconfirm the reading. This is the reading skill the rest of the programme trains — the teacher portal shows the same grid; the thinking is the same. | Hands-on |
| 1:50 10 min | Reflection + check Individually: “one task I will redesign this month to make two moves explicit; one thing I will look for in my next test’s results.” Then a short five-item check on the five moves, and the assignment is briefed. | Reflection |

Key ideas
CT is thinking, not typing
Decomposing a problem, noticing what repeats, keeping what matters, writing steps another person can follow and checking a claim against evidence happen in a Class 7 history lesson as naturally as in a computer lab. CBSE’s curriculum places CT inside Maths and The World Around Us for Classes 3–5 for exactly this reason.
Abstraction is the hard one
Students can usually break a task down; what they struggle with is deciding what to leave out. “Which of these facts about the two towns actually explains the crops?” is an abstraction question — and it is also the skill a teacher uses when ten wrong answers turn out to be one misconception.
An algorithm is a test of understanding
If a student can write the steps for solving a linear equation so precisely that a classmate can follow them blindly, they understand it. If the steps break on a new equation, the break shows exactly what they do not understand. Debugging is assessment.
Reasoning from evidence is the teacher’s move
A results grid is data; a gap is a claim about the data. The discipline is to say what pattern you saw, what you think it means, and what would change your mind — before you act. Every AI signal in the rest of this programme is read this way: as a hypothesis, not a verdict.
Worked example
A results grid, read computationally
Class 8-A, 40 students, a ten-item diagnostic on Linear Equations in One Variable, marked the usual way: the class average is 61%. That number suggests “revise the chapter”. (Numbers in this example are illustrative.)
Decompose by item: Q3, Q6 and Q9 are wrong for most of the class; the other seven are fine. Decompose by student: 11 students got all three wrong; 23 got all three right.
Pattern: the three questions look different — a word problem, an equation with brackets, a variable on both sides — but the wrong option those 11 chose is the same kind: a term moved across the equals sign with its sign unchanged.
Abstraction: this is not three questions. It is one concept — transposition changes the sign — and a 61% average hides it.
Algorithm: for those 11, a ten-minute reteach with the balance picture and six practice items; for the 23, an extension. Evidence check: if the reading is right, the same 11 get a fresh transposition item right next week; if they do not, the teacher looks again. Nothing in this needed a computer — and everything in it is what the teacher portal shows when the teacher opens results by question.
Assignment — counts towards certification
CT task redesign + results reading
Take one task you already set — a worksheet question, a map exercise, a comprehension, a practical — and redesign it so students must do at least two of the five moves explicitly: for example, write the steps as instructions, or find the rule across cases before applying it. Then read the results of any recent class test computationally: by item, by student, by shared wrong answer.
Deliverable: A one-page redesigned task (before / after, with the moves named) and a half-page reading of one real class result: the pattern you found, the concept you think it shows, and what would confirm it.
| Criterion | Meets the standard when… |
|---|---|
| Moves made explicit | At least two of the five moves are required of students by the task itself, not by a label added to an unchanged worksheet. |
| Subject-faithful | The redesign still teaches the chapter’s learning outcome; CT is the route, not a detour. |
| Grid read by item and by student | The reading names specific items and a specific group of students, not “the weak students”. |
| Evidence stance | The reading states what would confirm or disconfirm it and what the teacher will do first. |
Where this lands in the PrepGraph workflow
Each certification task corresponds to a behaviour in the teacher portal — so the programme produces a working habit, not a slide deck. The pedagogy comes first; the surface implements it.
| Certification task | Pedagogical move | PrepGraph surface |
|---|---|---|
| Read a class’s results by question and by student | Decomposition and pattern recognition on learning data | Assignments & resultsSet a short diagnostic or homework from the question bank; see who attempted, how each question went, and give feedback. |
| Treat an early-warning signal as a hypothesis to check | Reasoning from evidence | Early-warning signalsNightly signals per group — engagement dropping, scores slipping — so you know who needs a check-in this week. |
Materials
- •Five subject activity cards — Maths (Class 8 Linear Equations), Science (Class 10 Light), English (Class 6 formal letter), Social Science (Class 7 climate-and-crops tables), Classes 3–5 (Class 4 number patterns; a The World Around Us sorting task) — with facilitator answers
- •One-page co-teaching planner: subject teacher / computer teacher / students — what each does in 40 minutes
- •Printed results grid: 40 students × 10 items with option chosen, plus the concept map behind it (illustrative data)
- •Five-item check on the five moves, with answer key
- •Slides: five moves in school words; where CBSE places CT in Classes 3–5 and 6–8
- •Chart paper and markers, one set per subject group
Facilitator notes
- •Keep every device closed. The module is strongest when teachers realise the moves were always in their subject; a laptop turns it back into “computer class”.
- •If a group has no computer teacher, a maths teacher plays that role in the co-teaching planner — the point is two people agreeing who does what, not the job title.
- •In the results-grid activity, stop groups who say “the weak students” and ask “which students, which items, which wrong option?” The habit of naming is the whole skill.
- •Do not open the PrepGraph portal here. The grid on paper is deliberate: the thinking must exist before the screen shows it; Modules 5 and 6 add the screen.
- •Say plainly — and show the curriculum page — that CBSE places CT inside subjects for Classes 3–5 and as a collaboration for 6–8. Teachers worry it means a new period on the timetable; it does not.
- •If the school has nominated only its computer teachers for this module, push back before the day. CBSE places CT inside Mathematics and The World Around Us for Classes 3–5 and across subjects for 6–8 — a room of only computer teachers cannot run the subject stations, and the co-teaching planner has nobody to plan with.
- •Outcomes 4 and 6 — the co-taught period plan, and why the loop is CT applied to teaching — are checked in the session (the planner briefing and the five-item check), not by the assignment rubric; outcomes 1–3 and 5 are assessed by the assignment.
