B2.3 B2.2About 35 minutes
Learning goals- I can find the base word and the ending in a word.
- I can choose -s or -es to make a plural, and I know some plurals that change (like mice).
- I can spell -ed words, even when -ed sounds like /t/ or /d/.
- I can use the three spelling changes: double, drop the e, and change y to i.
Words to know
base word
The main part of a word, before anything is added. In jumping, the base is jump.
suffix
A word part added to the end of a base word, like -s, -ed, -ing, -er or -est.
plural
More than one. cats is the plural of cat.
morpheme
The smallest part of a word that has meaning. jump and -ed are both morphemes in jumped.
Words are like building blocks
Look at these words: jump, jumps, jumped, jumping, jumper.
They all have the same base word: jump. Different endings (suffixes) change the meaning a little.
- -s can mean more than one (cats) or it tells what someone does now (she jumps).
- -ed means it already happened (jumped).
- -ing means it is happening (jumping).
In Grade 1 you added endings to words like jump, and you met two spelling changes: doubling (hopping) and dropping the e (baking). Now you'll use those changes with more endings and learn a third one: change y to i.
A base word plus a suffix makes a new word.Plurals: -s or -es?
Most words just add -s: cat → cats, mitten → mittens.
Words ending in s, x, z, ch or sh add -es. Say them: you can hear an extra syllable!
- bus → buses
- box → boxes
- bench → benches
- dish → dishes
| One | More than one |
|---|
| mouse | mice |
| child | children |
| foot | feet |
| tooth | teeth |
| man | men |
| goose | geese |
| sheep | sheep |
Some plurals change the word instead of adding -s. Learn these by heart.-ed always looks the same
Say these words: jumped, played, melted.
The ending sounds like /t/ in jumped, /d/ in played, and /id/ in melted. But it is always spelled -ed! So never write jumpt or playd.
Three spelling changes
1. Double it. If a short word has one short vowel and ends with one consonant, double the last letter before -ing, -ed, -er or -est.
- hop → hopping, big → bigger, stop → stopped
(This keeps the vowel short. hoping without the double p would be a different word!)
2. Drop the e. If a word ends with a silent e, drop it before -ing, -ed, -er or -est.
- bake → baking, smile → smiled, nice → nicer
3. Change y to i. If a word ends with a consonant + y, change the y to i before adding -es, -ed, -er or -est.
- cry → cried, baby → babies, happy → happier
- But keep the y before -ing: cry → crying. (Two i's in a row would look strange!)
- If a vowel comes before the y, just add the ending: play → played.
Start at the top: look at how the base word ends, follow the arrow, and you'll know which spelling change to make before adding the ending.| Base word | Change | New word |
|---|
| run | double the n | running |
| skate | drop the e | skating |
| fly | y to i | flies |
| sad | double the d | sadder |
| hike | drop the e | hiked |
| funny | y to i | funniest |
| jump | no change | jumping |
Which change? Look at how the base word ends.Worked exampleLet's add -ing to "swim"
- Look at the end of swim: one short vowel (i) and one consonant (m).
- That means double the last letter: mm.
- Add -ing: swimming.
- Read it: swim-ming.
Worked exampleLet's add -ed to "try"
- try ends with y. What's before the y? r, a consonant.
- Consonant + y, so change y to i: tri.
- Add -ed: tried.
- Check: we are adding -ed, not -ing, so the change is right.
Just for funFunny but true: sheep is spelled the same for one or for many. One sheep, two sheep, one hundred sheep… 🐑 Counting sheep never needs an -s!
Hands-on activityEnding machine
You need: paper, scissors, a pencil.
- Make 4 small ending cards: -s/-es, -ed, -ing, -er.
- Write these base words on bigger cards: jump, hop, bake, cry, play, box, fish, swim, smile, big.
- Pick a base word and an ending card. Say the new word. Decide: does it need a spelling change? (double, drop e, y to i, or none)
- Write the new word.
- Use your new word in a sentence out loud.
Example: bake + ing → baking. "I am baking cookies with Grandpa."
Your turn
1What is the base word in playing?
foxes. Words ending in x add -es.
3What is the plural of mouse?
jumped. It sounds like /t/ but is spelled -ed.
hopping. One short vowel + one consonant, so double the p.
riding. Drop the silent e.
babies. Consonant + y, so change y to i.
More practice: warm-up
singing. No change: sing ends with two consonants (ng).
5What is the plural of foot?
More practice: on your own
bigger. One short vowel (i) + one consonant (g), so double the g.
smiled. It already ends with e, so just add -d (drop the e, then add -ed).
crying. Keep the y before -ing.
cried. Consonant + y, so change y to i before -ed.
5Make bench plural. How do you know?
benches. Words ending in ch add -es. You can hear the extra syllable: bench-es.
Challenge
1Fix this sentence: I was runing and skiped to the parck.
I was running and skipped to the park. run doubles the n (running). skip doubles the p (skipped). park uses k because r comes before the /k/ sound.
2Why are hoping and hopping different words?
hoping comes from hope (drop the e). hopping comes from hop (double the p). The double p keeps the o short.
3Add -est to happy, big and nice.
happiest (y to i), biggest (double g), nicest (drop e).

For parents and teachersBig idea: Grade 2 students use their knowledge of common morphemes (bases and suffixes) to read and spell words (B2.3), and the spelling patterns for adding suffixes: doubling, dropping silent e and changing y to i (B2.2).
How to help at home:
- When your child adds an ending, ask "What's the base word? How does it end?" before they write.
- Point out -ed words in books and sort them by sound (/t/, /d/, /id/). The spelling never changes.
- Practise irregular plurals in conversation: "One mouse, two...?"
Common difficulties:
- Spelling -ed the way it sounds (jumpt, playd). Remind them: "-ed is always -ed."
- Forgetting to double (hoping for hopping). Ask: "Is the vowel short? Is there just one consonant at the end?"
- Keeping the silent e (bakeing). "The e jumps off when -ing comes."
- Changing y to i before -ing (criing). Keep the y before -ing.
- These rules take time. Grade 2 is about building awareness; accuracy grows through Grade 3.
