Singular and Plural for Class 2
The harder rules, with three free worksheets
Class 2 takes singular and plural past the add s and add es of Class 1. Four harder rules arrive. A consonant before y turns into ies (city, cities), while a vowel before y simply adds s (boy, boys). Most words ending in f or fe become ves (leaf, leaves), apart from roof, chief and belief. A consonant before o usually takes oes (mango, mangoes), though photo and piano take a plain s. And a small set of nouns never change at all (sheep, deer, fish) while another set is always plural (scissors, trousers, spectacles).
Three free worksheets sit below, one A4 page each, with every answer key printed in this article. Sheet 1 drills both halves of the y rule. Sheet 2 covers f to ves and the o endings. Sheet 3 mixes everything, adds the no-change and always-plural words, and asks your child to rewrite a whole sentence from one to many, which is where is quietly has to become are.
No sign-up. Answer keys are further down this page.
- The y rule has two halves and children only ever get taught one. A consonant before y takes ies (city, cities). A vowel before y just takes s (boy, boys, monkey, monkeys). Checking that single letter fixes most Class 2 plural mistakes.
- f and fe usually become ves (leaf, leaves), and the whole exception list is roof, chief and belief. Teach the rule first and the three words second, never the other way round.
- Not every noun moves. Sheep, deer and fish stay exactly as they are, while scissors, trousers and spectacles only exist in the many form.
- Changing one to many changes the words around the noun too. This is a box becomes These are boxes, and the word children miss is is, not box.
What Class 2 adds to singular and plural
By Class 2 your child already knows the ordinary plural. One cat, two cats. One bus, two buses. That was Class 1 and it is largely done. What arrives this year is the awkward middle of English spelling: words where the ending has to be reshaped before an s can go on it, and small groups of words that refuse to move at all.
Nearly every mark lost in Class 2 comes from the same habit. Your child learned a rule last year, it worked on almost every word they met, and now it is being applied to words that will not take it. Citys. Leafs. Mangos. Sheeps. None of those are guesses. Each one is a rule being used faithfully in the wrong place, which is why sharp correction backfires here.
Here is the whole Class 2 topic on one table. Stick it inside the front cover of the notebook and you have covered the year.
| Rule | When it applies | Examples | Watch out for |
|---|---|---|---|
| y becomes ies | A consonant sits just before the y | city, cities · bunny, bunnies · family, families | Children stretch this onto boy and key as well |
| y stays, add s | A vowel (a, e, i, o, u) sits just before the y | boy, boys · key, keys · day, days · monkey, monkeys | Monkey looks like it wants ies. It does not. |
| f or fe becomes ves | Most words ending in f or fe | leaf, leaves · knife, knives · wolf, wolves · half, halves | The f turns into a v sound when you say it |
| f, but just add s | A three word exception list | roof, roofs · chief, chiefs · belief, beliefs | Rooves is the most common wrong answer of the year |
| o becomes oes | A consonant sits just before the o | mango, mangoes · potato, potatoes · hero, heroes | The e is easy to drop when writing quickly |
| o, but just add s | A vowel before the o, plus photo and piano | radio, radios · video, videos · photo, photos · piano, pianos | Photo and piano have to be learned, not worked out |
| No change | The word is identical for one and for many | sheep, sheep · deer, deer · fish, fish | The number word carries the meaning: nine sheep |
| Always plural | The word only exists in the many form | scissors · trousers · spectacles · shorts | We say a pair of scissors, never one scissor |
Three things are worth noticing before you drill any of it.
- The two y rows are one decision, not two. Your child never has to remember which words take ies. They only have to look at the single letter sitting in front of the y, and they have known the vowels since nursery.
- The two exception rows are lists, not rules. Roof, chief, belief, photo, piano. Five words in total for the whole year. Learn them the way you learn a phone number and stop trying to explain them.
- The last two rows are about the whole sentence. Nine sheep were resting. My scissors are blunt. Nothing happened to the noun, so the child has to hear the verb instead, and that is a listening skill more than a spelling one.
If the basics are still shaky, go back a year first. The Class 1 singular and plural worksheets cover add s and add es, and there is no point layering the y rule on top of a wobbly foundation. Everything else your child needs this year sits in all the Class 2 English worksheets.
Worth knowing: most CBSE schools teach Class 2 from NCERT's Marigold Book 2 and Raindrops 2, and the plural work is spread thinly across the whole year rather than taught in one block. That is exactly why a child can be steady in October and shaky by January. Ten minutes of revision beats waiting for the next chapter to come round.
City becomes cities, but boy becomes boys
This is the rule Class 2 children get wrong most often, and not because it is difficult. It is because half of it stays invisible until somebody points at it.
Your child is taught y becomes ies. Baby, babies. City, cities. It works, so they use it everywhere, and within a month they are writing boies and keies and monkies. The rule was never y becomes ies. It was a consonant before y becomes ies, and those first four words rarely get said out loud.
Three seconds fixes it, and the same three seconds work on every word for the rest of their schooling.
Cover the y with a fingertip
Literally. Put a finger over the last letter and look at what is now sitting at the end of the word. In city it is t. In boy it is o. That one letter decides everything, so it has to be seen before a single mark goes on the page.
Ask: is it a, e, i, o or u?
Those five are the vowels and your child has known them for years. This step asks for nothing new at all, which is precisely why it holds up in a class test when the freshly taught rule has gone fuzzy.
Vowel keeps the y, consonant loses it
A vowel in front means leave the word alone and add s. Boy, boys. Key, keys. A consonant in front means rub out the y and write ies. City, cities. Bunny, bunnies. Two outcomes, one question.
Sorted into the two halves, with the words your child is most likely to meet this year:
- Consonant before the y, so ies: city, cities. Bunny, bunnies. Family, families. Party, parties. Candy, candies. Fly, flies. Army, armies. Cherry, cherries. Penny, pennies.
- Vowel before the y, so just s: boy, boys. Key, keys. Day, days. Toy, toys. Tray, trays. Monkey, monkeys. Donkey, donkeys. Valley, valleys. Chimney, chimneys.
Monkey is the word to test with. It ends in y, it looks like an obvious candidate for ies, and the quiet e in front of the y is the only thing saving it. A child who writes monkeys without pausing has understood the rule. A child who pauses has memorised a list, and lists run out.
Try this while the rice cooks: say a y word and ask for the many word before anything is written down. Trolley. Cherry. Chimney. Puppy. Valley. Berry. Five seconds each, no paper at all, and the answers come from the ear rather than from a page your child can copy from.
Leaf becomes leaves, mango becomes mangoes
Both of these rules came out of the way English is spoken, and both arrive with a short list of words that ignore them.
f and fe become ves. Say leaf, then say leaves. The f softened into a v. That is not decoration, it is the reason the spelling moves: the word genuinely sounds different in the many form and the letters are only following the mouth. Ask your child to say both back to back and they will hear it without being told.
A consonant before o takes oes. Mango, mangoes. Potato, potatoes. This one has no sound behind it that a seven year old can detect, so it has to be learned as a pattern, and the pattern has the same shape as the y rule: look at the letter sitting before the o. A vowel there and the word simply adds s, which is why radio, video and zoo cause nobody any trouble.
| Word ending | What happens | Examples | The words that refuse |
|---|---|---|---|
| f or fe | Swap the ending for ves | leaf, leaves · knife, knives · wolf, wolves · half, halves · loaf, loaves · thief, thieves · shelf, shelves · wife, wives | roof, roofs · chief, chiefs · belief, beliefs |
| consonant + o | Add oes | mango, mangoes · potato, potatoes · tomato, tomatoes · hero, heroes · volcano, volcanoes | photo, photos · piano, pianos |
| vowel + o | Add s | radio, radios · video, videos · zoo, zoos · bamboo, bamboos | None. This row is safe. |
That last column is the entire difficulty of this section, and it is five words long. Roof, chief, belief, photo, piano. If your child can say those five back to you, everything else here is reasoning rather than memory.
- Rooves is the single most common wrong answer in the whole topic. It is the ves rule working perfectly on a word that will not have it, so treat it as a near miss rather than a mistake.
- Mangos appears in some dictionaries, but Indian school answer sheets mark mangoes, so teach the e and save your child an argument they cannot win in an exam hall.
- Photo keeps a plain s because it is short for photograph. Your child does not need that reason, but knowing it stops the word feeling random to you when you are the one explaining it.
- Half and halves is worth a minute on its own, because it turns up in maths lessons all year and children write halfs long after they have stopped writing leafs.
Say it, then spell it: for the f words, have your child say the one word and the many word back to back before writing either. Leaf, leaves. Knife, knives. Wife, wives. Shelf, shelves. The v is audible every single time, and a child who can hear the change stops needing to remember which words are on the list.
Words that never change, and making the sentence agree
Two small groups of nouns sit outside every rule above. Then there is the part that catches almost every Class 2 child, no matter how well the spelling has gone.
Some nouns do not move at all. One sheep, nine sheep. One deer, four deer. One fish, six fish. Nothing is added and nothing changes shape. The number word in front is carrying the entire meaning, and that feels plainly wrong to a child who has spent two years learning that many means s on the end.
Some nouns are only ever plural. Scissors. Trousers. Spectacles. Shorts. There is no such thing as one scissor, because the word is naming something built from two matching halves. When we need to count them, we count pairs: a pair of scissors, two pairs of trousers.
| Word | One or many? | A sentence to read aloud |
|---|---|---|
| sheep | Same for both | Nine sheep were grazing near the well. |
| deer | Same for both | We saw four deer near the forest gate. |
| fish | Same for both | Dada caught six fish before lunch yesterday. |
| aircraft | Same for both | Two aircraft landed in the thick fog. |
| scissors | Always many | My scissors are blunt, so use the new pair. |
| trousers | Always many | These trousers were far too long for Karan. |
| spectacles | Always many | Nani's spectacles were lying on the newspaper. |
| shorts | Always many | His shorts are drying on the line outside. |
Now the part that a fill-in-the-blank page cannot teach, however many blanks it has. When one becomes many, the noun is not the only word that has to change.
- This is a box becomes These are boxes. Three separate changes, and most children make one of them.
- That was a sharp knife becomes Those were sharp knives. Again three, and was is the one that survives untouched.
- The sheep was resting becomes The sheep were resting, with nothing at all happening to the noun itself.
Read that last one again. Nothing on the page tells you it is plural except the word were. This is exactly why worksheet 3 asks for the full rewritten sentence instead of a single missing word: a blank hides the thing Class 2 most needs your child to notice.
The two second check: once your child has rewritten a sentence, ask them to read it out loud. These is boxes sounds wrong immediately, even to a child who could not explain why if you asked. The ear catches agreement mistakes long before the eye does, which is the whole argument for reading aloud at this age rather than only writing.
Answer keys for all three worksheets
Everything below runs in the same order as the printed page, with the rule named in brackets wherever the answer is one children argue about. Mark it sitting beside your child. The useful minute is not the ticking, it is asking why they wrote what they wrote.

- a. five boys
- b. three keys
- c. seven days
- d. nine toys
Exercise 3: Put each word in the right box
- y becomes ies: bunny, cherry, army, penny (a consonant sits before the y in all four)
- Just add s: monkey, toy, key, tray (a vowel sits before the y in all four)

Worksheet 3
Exercise 1: Write the plural. All the rules are mixed up.
- a. six donkeys (vowel before the y)
- b. two wives (fe becomes ves)
- c. three hobbies (consonant before the y)
- d. five tomatoes (consonant before the o)
Exercise 2: These words do not change at all

- c. one wife
- d. one potato
Exercise 5: Write the whole sentence for many
- a. These are four big boxes. (this becomes these, is becomes are)
- b. Those were two sharp knives. (that becomes those, was becomes were, fe becomes ves)
- c. Six sheep were resting under the tree. (the noun stays exactly as it is, only was becomes were)
A wrong answer here tells you something specific, so it is worth knowing which kind you are looking at before you decide what to do about it.
| What went wrong | What it means | What to do next |
|---|---|---|
| Exercises 1 and 2 on sheet 1 are mixed up | The letter before the y is not being checked | Cover the y with a finger and redo four words out loud, no writing |
| Rooves, or mangos without the e | The rule is solid, the exception list is not | Five words on one card: roof, chief, belief, photo, piano |
| Sheeps, deers, fishes | The add s rule is strong, which is good news | Use the words in ordinary talk this week instead of retesting them |
| The noun is right but is or was is unchanged | Only the agreement is missing | Read both versions aloud together and let the ear find it |
Mark the rewrite differently. Exercise 5 on worksheet 3 has no half marks worth arguing over. Either every word that had to move has moved, or one slipped past. If knives is right and was is still was, your child owns the plural rule and has simply never been shown that the rest of the sentence travels with it. Say both versions aloud and they will pick out the wrong one themselves.
The s in cats, the z in dogs, the iz in boxes
A worksheet can check whether your child spelled knives correctly. It cannot hear whether the v was said, or whether the plural ending arrived at all when the sentence was read out loud. That matters more than it sounds. The s in cats is a hiss, the s in dogs is really a z, and the es in boxes adds a whole extra beat. Three different sounds and one letter on the page, so this is a topic the ear learns before the pencil does.

Frequently asked questions
Singular means one and plural means more than one. Class 2 goes past the simple add s and add es rules of Class 1. Your child now learns that a consonant before y turns into ies, that f and fe often become ves, that some o words take oes, and that a few nouns like sheep never change at all.
Look at the letter just before the y. If it is a consonant, the y goes and ies takes its place, so city becomes cities and baby becomes babies. If it is a vowel, which means a, e, i, o or u, the word simply adds s: boy becomes boys, key becomes keys, day becomes days.
Most words ending in f or fe swap that ending for ves: leaf becomes leaves, knife becomes knives, wolf becomes wolves, half becomes halves. A handful refuse and simply add s. The common ones in Class 2 are roof, chief and belief, giving roofs, chiefs and beliefs. Teach the ves rule first, then the three exceptions as a short list.
Mangoes, with the e. Words ending in o that follow a consonant usually take oes: mango, potato, tomato, hero, volcano. Words where a vowel comes before the o just add s, like radio, video and zoo. Two everyday words break the pattern completely and take plain s: photo becomes photos and piano becomes pianos. Say them out loud and the extra e is easy to remember.
A small group stays exactly the same whether you mean one or many: sheep, deer, fish and aircraft. One sheep, nine sheep. A second group is always plural and never drops the s, so we say a pair of scissors rather than one scissor, and the same goes for trousers and spectacles. Children write sheeps because the add s rule is strong by Class 2.
Because the blank on a worksheet only asks for the noun. Changing one to many moves the whole sentence: this becomes these, is becomes are, was becomes were. Worksheet 3 on this page drills exactly that, by asking for the full rewritten sentence rather than a single word. If your child writes These is boxes, the plural rule is fine and only the agreement is missing.
