Tutor lesson-prep guides · Primary English

A pupil who writes a red big bag is not careless; nobody has told them adjectives have slots. This lesson draws the eight slots as one line and uses 8 factorial to show how badly random order fails, so order becomes something a pupil can check.

Objectives — By the end pupils can: (1) name the 8 adjective types in order (opinion, size, age, shape, colour, origin, material, purpose) and arrange three adjectives into one correct phrase; (2) compute that 8 types allow 40320 arrangements and only one is correct; (3) state that two adjectives take and, while three or more take commas and a final and.

01 Prerequisites (3-minute check)

If any of these fails, fix it before the lesson starts.

Skill	Quick check	Pass mark
Adjective position	Does an adjective go before or after the noun?	Before
Simple multiplication	How many ways can three items line up?	Six
Commas in lists	How do you separate three items?	Commas then and

03 Teaching script (read it out)

Scene 1: Eight slots on one line

The order is opinion, size, age, shape, colour, origin, material, purpose. Teach it as one line: opinion first, material and purpose closest to the noun. Model one sentence: a lovely small old round brown wooden garden chair, labelling each word with its slot.

Say plainly that nobody needs eight adjectives at once. Real writing uses one to three. The order is for arranging what you already have, not for filling every slot.

Opinion comes first, material and purpose sit nearest the noun

Scene 2: The factorial: why the order is learned, not felt

If 8 types can be shuffled freely there are 40320 arrangements, and only one sounds natural to a fluent speaker. Three adjectives give 6 arrangements, four give 24.

Use the numbers to make one point: the order is not a matter of taste, it is one arrangement out of 40320, so it must be learned as a rule.

8 types give 40320 arrangements, only one correct

Scene 3: Punctuation: and for two, commas for three

Two adjectives of different types may take and or a comma, but two of the same type always take and: big and small, never big small. Three or more take commas with and before the last one: a big, old, wooden box.

The usual slip is commas everywhere with no final and, or an and in the middle. Give pupils one checking action: count the adjectives, then apply and for two, commas plus and for three or more.

Two adjectives take and; three or more take commas plus a final and

04 Question types and worked steps

Type	Example	Steps	Answer
Ordering	Arrange big, red and wooden into a phrase	Follow size, colour, material	a big red wooden box
Calculation	How many arrangements do 8 types allow	Take 8 factorial	40320
Punctuation	How do three adjectives separate	Count them: commas plus and	a big, old, wooden box
Correction	What is wrong with a red big bag	Check the slots: colour has jumped ahead of size	a big red bag

Sanity check (teach this): Sanity check: only %d adjective types and three factorial figures appear (%d, %d, %d), all computed by script; examples are classroom objects with no brand names; no exception cases are taught, because P4 and P5 need one stable rule; no pupil is asked to use more than three adjectives, which keeps the sentence from becoming a pile; all Chinese support stays at words a pupil already knows.

05 Independent practice (3 questions)

Question	Answer	What to watch
Ordering	Arrange six sets of adjectives	Check colour is not placed after material
Calculation	How many arrangements for four adjectives	Check they use 24, not double it
Punctuation	Repunctuate four phrases	Check the final and is present

06 Common mistakes and what to say

Mistake	Student writes	Say this
Colour too early	a red big bag	Size comes before colour: a big red bag. Colour sits close to the noun.
Comma between same types	a big, small box	Two of the same type take and: a big and small box.
Missing and with three	a big, old, wooden box with no and	With three or more, put and before the last adjective; count first.
Material too early	a wooden big box	Material hugs the noun: a big wooden box. The further from the noun, the more opinion-like.

08 Exit check (last 5 minutes)

Question	Answer	Decision
Eight slots	Name at least six and arrange one phrase	Fewer than six means redraw the line
Factorial	8 types give 40320 arrangements	Wrong means reteach act two
Punctuation	Three adjectives take commas plus and	Wrong means redo the four phrases

09 Tutor FAQ

Must pupils learn the English type names?

For P4 and P5 the Chinese labels plus one example each are enough; the English names can follow in P6.

What about exceptions to the order?

They exist but are not for primary. Teach the stable rule first and leave exceptions to secondary writing.

Can I teach only three types?

Yes, split it: opinion, size, colour and material in lesson one, the other four in lesson two.
