Adding suffixes when the root word has to change
Add -ed, -ing, -er and -est to root words that change: y to i, the dropped e, and the doubled final consonant.
Board title: Change the word first · Say it: “Today, before we add an ending, we're checking the last letter of the word: the y might change, the e might drop, or a short word doubles.”
root word · ending · suffix · vowel · consonant · double
Doubling everything. jumpping, helpping, wantted. The new rule spreads to every word within a day. Ask "is it a short word with one last letter?" before the pencil moves.
Changing every y. plaing, enjoied. The y only changes after a consonant. After a vowel it stays: playing, enjoyed. Task 2 on the hottest sheet has one.
Keeping the e. rideing, makeing, timeing. The commonest error on the page. Say it as a phrase: the e steps aside so the ending can sit down.
Treating -er and -est differently. They learn happy → happier but write happyest. The same three rules govern all four endings. Show one root taking two endings.
Same four tasks on every sheet, in the same order, with the same look. Only the demand changes. Print the one each child needs; nobody does two.
Same four tasks as every other sheet, same order, same look, the demand is lower, not the dignity. Shorter passage in Task 2, and in Task 3 a word bank or words to tick, with printed sentence starters. Give it to anyone who needs a way in, and expect them to move up.
The core sheet. Give this to most of the class. No word bank; in Task 3 pupils choose from a few close options, then use one in a sentence of their own.
Same four tasks, more demand, a longer passage with a subtler error, and Task 3 asks for two things at once. Not extra work; harder work. Nobody should be doing Spicy and the Medium sheet.
