Word Families

Word families from a common root

Lesson 3 of 10
Year 3 45 min

Objective

Recognise the root inside a longer word and use it to work out both meaning and spelling, and judge by meaning whether two words really belong to the same family.

Board title: Word families  ·  Say it: “Today we're finding the root hiding inside long words and using it to work out meaning and spelling, and catching the words that only look like family.”

Curriculum

  • Y3: word families based on common words, showing how words are related in form and meaning (solve, solution, solver, dissolve)
  • Y3: prefixes and suffixes (Appendix 1), the same roots, differently dressed
  • Terminology: word family · root word · prefix · suffix
  • STA domain: vocabulary G6/G7

Success criteria

  • find the root hiding inside a longer word
  • build new words from one root
  • use the root to work out what a word means
  • spot a word that only looks related

Key vocabulary

word family · root · prefix · suffix · related · meaning

Run of the lesson

5 min
Starter: write solve → solution and butter → but on the board. If two words share letters, are they family? Take answers, say 'hold that thought' and move on.
11 min
Model on the board: cover the prefix and suffix of unhelpful with your hands so only help shows, physically, before they try it in their heads. Then the harder idea, worth the time: solve and solution do not look identical and are still family. Build the tree outwards with dissolve, decision, pleasure, asking each time: does the long word still mean the small one?
8 min
Flavour Match, Medium band, level 3 is the word-family set (help/helpful, act/action) with deliberate near-misses, hopeful for helpful, station for action. Read the badge aloud, same family, not same meaning, and say the root before you tap.
5 min
Trap and votes: butter = but + ter, the letters line up by accident. Four votes with WHY (answers: a-left, b-right, c-right, d-left).
13 min
Worksheet, independent. Circulate on Task 3: the tell is a child matching letters instead of meaning, so ask them to say what their root means and show that meaning still inside the word they built from help or play.
3 min
Plenary: two children read a Task 3 sentence and the class names the root inside each long word. Then the class quiz: which of corn, corner and cornflake does not belong?
On screenSPAGhetti → Flavour Match → Medium. One screen only; no pupil devices needed. Read the bank first: Medium levels 1 and 2 are synonyms and antonyms, and level 3 is the word-family set you want, help/helpful, play/player, care/careful, act/action, teach/teacher. The distractors there are deliberate near-misses (helpful vs hopeful, action vs station), which is exactly the discussion. The Word Cellar bank is the natural follow-up if you have a second session: same roots, building outwards with prefixes and suffixes.

On the day

If the tech failsSkip the game entirely. Task 1 is the same content on paper, read the four pairs aloud and vote with thumbs. Or write one root on the board and have the class call out family members while you build the tree.
If they're on devicesLesson code FMLYC (on the worksheet footer) opens the right game, locks the café until 10 items are done, then unlocks it as the reward.

Misconceptions to watch for

False friends. carpet from car, butter from but, corner from corn. They match letters because letters are visible and meaning is not. The test is always the same question: does the long word still mean the small one?

Family means the same meaning. helpful and helpless are one family and near opposites. The game mixes synonym, antonym and family rounds, so read the badge with them. Family is about where a word came from, not what it means now.

The root must look identical. solve and solution get rejected because the letters shift. Show three shifting pairs together, solve/solution, decide/decision, please/pleasure, so the shift itself becomes the expected thing rather than the surprise.

A root is not half a compound. Straight after compound work they split signature into sign + ature and expect both halves to be words. A prefix or suffix is not a word on its own, only the root has to be.

The three sheets

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.

Mild

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.

Medium

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.

Spicy

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.

Adaptive teaching

  • Support: give the root printed on a card; they find it inside three long words by underlining. Game on Mild.
  • SEN: gentle mode on; read Task 2 aloud before they edit.
  • Stretch: Task 3 extension, find a family with four members and put two of them in one sentence.
  • EAL: roots travel between languages. Ask what solution or magic sound like in their first language, the family is often wider than the class expects.
