Primary 4 English | Comparatives and Superlatives: syllables decide -er or more

2026-11-10

Tutor lesson-prep guides · Primary English

A pupil can write bigger but turns beautiful into more beautifuler. This lesson teaches one decision only: count the syllables, then choose -er or more.

Objectives — By the end the pupil can: (1) count syllables and choose between -er/-est and more/most; (2) apply the y to ier rule and the double consonant rule correctly; (3) write full sentences with than after a comparative and the before a superlative, and recall three irregular adjectives.

01 Prerequisites (3-minute check)

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

Skill	Quick check	Pass mark
Adjectives	What kind of word is big or tall	An adjective that describes a noun
Syllables	How many syllables are in happy	Two
The	What does the usually come before	A particular person or thing

02 Lesson flow (40 minutes)

Time	Stage	Tutor does	Student does
0-5 min	Diagnose	Ask who is taller out of two people	An answer with taller means they are ready
5-17 min	Sort by syllables	Sort 9 adjectives into add -er, drop y add ier, and add more	Sort them alone
17-30 min	Write sentences	Comparative with than, superlative with the	Two sentences per group
30-36 min	Irregulars	good, bad and many	Write all six forms
36-40 min	Exit check	Mark three items live	Three out of three

03 Teaching script (read it out)

Scene 1: Sort the syllables first, choose the method second

Almost every error comes from adding -er on sight. The order is: count the syllables, add -er/-est to one syllable, drop y and add -ier/-iest to a two syllable word ending in y, and use more/most for everything longer.
One contrast does the work: tall, taller, tallest takes a suffix, while beautiful, more beautiful, most beautiful cannot, because three syllables plus a suffix is unreadable.
Ask for the syllable count out loud before every answer and the choice follows.

Ask the pupil: sort 9 adjectives into three columns and write the syllable count under each.

Scene 2: The y rule and the double consonant rule are separate

Happy becomes happier and easy becomes easier: a consonant plus y drops the y and adds ier. Big becomes bigger and hot becomes hotter: a short vowel plus one consonant doubles the last letter before -er.
Drill the two rules apart, because pupils blend them into happyer or biger. Have them circle the ending first, y or a short vowel plus one consonant, and only then write.
Short model sentences work best: This bag is heavier than that one.

Ask the pupil: why is easy easier and not more easy?

Scene 3: Than for two, the for three or more, irregulars by heart

A comparative needs a rival introduced by than; a superlative needs a group and takes the. A missing the is the second most common lost mark after double comparison.
Three irregulars must be automatic: good, better, best; bad, worse, worst; many, more, most. Many and much share more, which is why manyer appears.
Close with one line: comparing is two things, the superlative is three or more.

Ask the pupil: fix one wrong sentence and say how many places changed.

04 Question types and worked steps

Type	Example	Steps	Answer
Gap fill	Choose -er/-est or more/most	Count syllables, choose, write	Three or more syllables take more
Sentence rewriting	Join two sentences into a comparison	Find the rival, add than, check the ending	Only one comparative per sentence
Picture comparison	Three people by height	The tallest one takes the tallest	The before a superlative
Short text	9 gaps in a 60 word text	Scan every gap first, then fill	Irregular forms spelled right

Sanity check (teach this): Check the numbers: the lesson is 40 minutes and the five stages must add up to 40; the three columns hold 9 adjectives and only 3 of them are irregular; one comparative per sentence, so more taller is wrong; a superlative without the counts as wrong.

05 Independent practice (3 questions)

Question	Answer	What to watch
9 gap fills	Spread evenly over the three columns	Check whether syllables were counted first
4 rewrites	Two sentences into one, same meaning	Both than and the comparative present
3 picture sentences	Three people compared by height	The before the superlative
Irregular recall	Three forms each for good, bad and many	better, worse and more are the usual errors

06 Common mistakes and what to say

Mistake	Student writes	Say this
Double comparison	“more bigger”	You may use -er or more, never both. Which did you choose?
Missing the	“He is tallest in the class.”	A superlative is unique, so what must come before it?
The y rule	“happyer”	What letter does happy end with? What replaces it?
than and then	“taller then me”	Then is about time; comparisons use than. They sound different too.

Prep guide master index — Comparable chapters in other subjects
Redo this chapter — Questions 1 to 4 again, syllable count first

08 Exit check (last 5 minutes)

Question	Answer	Decision
Comparative of beautiful	more beautiful	beautifuler means back to act one
What goes before a superlative	the	No article means back to act three
Three forms of good	good, better, best	gooder means the irregulars were missed

09 Tutor FAQ

How many irregulars must be memorised?

Three is enough at primary: good, bad and many. Everything else follows the rules.

Do two syllable words always take more?

No. Two syllables ending in y take -ier, as in happy to happier; most others take more.

Must a comparative sentence include than?

If there is a rival in the sentence, yes. Standalone comparisons can drop it, but exams expect a full sentence.
