Introduce, or Join?

Colons and semi-colons between clauses

Lesson 13 of 16
Year 6 45 min

Objective

Use a colon to introduce an explanation or answer, use a semi-colon to mark the boundary between related independent clauses, and repair comma splices.

Board title: Colon or semicolon  ·  Say it: “Today we're choosing between two marks: the colon that introduces what a sentence promised, and the semicolon that joins two whole sentences.”

Curriculum

  • Y6: using semi-colons, colons and dashes to mark the boundary between independent clauses
  • Y6: using a colon to introduce a list (taught in its own lesson)
  • Y3: clauses and conjunctions (revisited)
  • Terminology: colon · semi-colon · clause

Success criteria

  • use a colon to introduce what was promised
  • join two related sentences with a semicolon
  • check both halves could stand alone
  • say why a comma cannot join two sentences

Key vocabulary

colon · semi-colon · clause · independent · introduce · join · comma splice

Run of the lesson

5 min
Starter: The oven is hot. The pan is ready. against The oven is hot; the pan is ready. Both are correct, so what changed? Do not resolve it.
10 min
Model the two verbs. Colon: read The reason was simple alone and let them feel the itch for the answer. Semicolon: Leo washed up; Mia dried, read each half alone and check both stand. Then show a comma failing at the same job: The soup was cold, the service was slow.
8 min
The Recipe Card, Medium band: level 1 joins with semicolons, level 2 chooses colon or semicolon, and one round of level 3 shows the dash is legal too. Class votes before you tap; ask for the verb, introduce or join, each round.
5 min
Trap and votes: name the comma splice plainly, a comma cannot hold two sentences, could a full stop go there? Four votes, each half read alone before the reveal (answers: a-left, b-right, c-left, d-right).
14 min
Worksheet, independent. Circulate on Task 3: make them prove each semicolon by reading its two halves alone; the tell is a semicolon before a list, where the promise-keeping colon belongs.
3 min
Plenary: two children read a Task 3 sentence one half each, with a beat of silence for the mark, and the class calls introduce or join. Then the class quiz: what could hold The oven is hot, the pan is ready together?
On screenSPAGhetti → The Recipe Card → Medium. One screen only; no pupil devices needed. Medium is exactly this objective: level 1 joins with semicolons, level 2 chooses colon or semicolon, level 3 lets the dash do the same boundary work, worth one round so nobody thinks the dash is illegal. ~8 items in 10 minutes with discussion.

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. Then write one comma splice on the board and mend it three ways: full stop, semicolon, joining word. The lesson still works.
If they're on devicesLesson code CLSEF (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

The comma splice. The soup was cold, the service was slow. It reads smoothly aloud, which is why they write it. The test is mechanical: could a full stop go there? Then a comma cannot. This one error decides more secondary-school marks than any other in the lesson.

A capital letter after the mark. The soup was cold; The service was slow. Neither mark ends a sentence, so no capital follows either, unless the next word is a name. Quick to fix once named.

The semicolon used as a fancy colon. Bring three things; a knife, a board and a cloth. Before a list, the promise-keeping mark is the colon. The semicolon needs a whole sentence on each side, a knife is not one.

Semicolon plus a joining word. The soup was cold; but nobody minded. The semicolon replaces the joining word; you use one or the other. With but, a comma is right. Without it, the semicolon earns its place.

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: the semicolon only. Ten spliced pairs; mend each with a full stop or a semicolon and say which feels closer. Game stays on Medium level 1.
  • SEN: gentle mode on; read Task 2 aloud with a deliberate full-stop pause at every boundary before they edit.
  • Stretch: Task 3 extension, the same pair joined four ways: full stop, semicolon, dash, joining word, and a line on which they would print.
  • EAL: several languages join sentences with a comma quite correctly. Name that respectfully, then anchor the English rule to the full-stop test.
