A new punctuation mark

You've already seen colons in times, like 7:30. In Grade 5 you'll use a colon in a sentence to introduce a list.

For winter camp, bring three things: a warm toque, waterproof mittens and a sleeping bag.

The colon works like a drumroll. It says: Here comes the list!

A red knitted toque, a pair of black waterproof mittens and a rolled-up blue sleeping bag laid out on a cabin floor.

The colon rule

Use a colon before a list only when the words before the colon make a complete sentence.

  • Correct: We saw many animals: a moose, two foxes and a heron. (We saw many animals. is a complete sentence.)
  • Not correct: We saw: a moose, two foxes and a heron. (We saw. is not complete. Saw what?)
  • Fix: We saw a moose, two foxes and a heron. (No colon needed!)

Don't put a colon right after a verb (are, is, need, include) or after a preposition (of, for, to). Words like the following or these are good clues that a colon fits: Please bring the following: ...

We saw many animals:a moose, two foxes and a heronCover the list: “We saw many animals.”complete sentence: colon OK✔We saw:a moose, two foxes and a heronCover the list: “We saw.”Saw what? Not complete: no colon✘
The cover-up test: hide the list and read what's left. A colon is only correct when the words before it make a complete sentence.

The cover-up test

Cover the list with your hand. Read only the words before the colon, and put a period at the end. Is it a complete sentence? Then the colon is correct. If not, take the colon out.

Worked example

Let's test two colons

Which sentence uses the colon correctly? (A) My favourite seasons are: spring and fall. (B) I have two favourite seasons: spring and fall.

  1. Cover the list in (A): My favourite seasons are. That's not complete. Are what? ✗
  2. Cover the list in (B): I have two favourite seasons. That's a complete sentence. ✓
  3. Fix (A) by removing the colon: My favourite seasons are spring and fall.

(B) is correct. (A) needs no colon.

Commas in a list

After the colon, separate the list items with commas: a toque, mittens and a sleeping bag. Many writers also put a comma before the last and (a toque, mittens, and a sleeping bag). Both are accepted; just be consistent in one piece of writing. Your teacher may tell you which style to use.

If the list is a list of phrases or short items, don't capitalize the first item after the colon (unless it's a proper noun).

Your Grade 5 editing checklist

In Grade 4 you edited with CUPS. In Grade 5, add everything you've learned this year. Read your writing several times, looking for one kind of mistake each time:

CheckAsk yourself
CapitalsSentence starts, names, proper adjectives (Canadian, Inuit), titles, I?
Usage and grammarAny fragments, run-ons or comma splices? Right pronouns (me/I, themselves)? Correlative pairs matched (neither...nor)?
PunctuationEnd marks? Commas in compound and compound-complex sentences, around appositives, after opening phrases? Colons only after complete sentences?
SpellingTricky suffixes (-able/-ible, -ence/-ance)? Confused words (than/then, affect/effect)? Canadian spelling?
FormatTitle? Paragraphs indented or spaced? Headings and fonts easy to read?
CUPS plus format
CCapitalsread #1UUsageread #2PPunctuationread #3SSpellingread #4FFormatread #5One kind of mistake per read-through: your eyes catch more.
Edit in passes: read your writing five times, hunting for just one kind of mistake each time.
Worked example

Let's edit a paragraph

Edit: last saturday my family went to the Royal Ontario Museum, we saw: dinosaur bones, a totem pole and egyptian mummies. My little brother liked the dinosaurs more then the mummies.

  1. Capitals: last → Last; saturday → Saturday; egyptian is a proper adjective → Egyptian.
  2. Usage: ...Royal Ontario Museum, we saw... is a comma splice. Make two sentences.
  3. Punctuation: We saw: isn't complete. Remove the colon, or add words to make a complete sentence before it.
  4. Spelling: more then compares, so → than.

Last Saturday my family went to the Royal Ontario Museum. We saw many amazing things: dinosaur bones, a totem pole and Egyptian mummies. My little brother liked the dinosaurs more than the mummies.

Just for fun

Things a colon is great at: lists, drumrolls and dramatic pauses.

Things a colon is bad at: telling knock-knock jokes. It always gives away the answer!

Hands-on activity

Packing list and edit

You need: paper, a pencil, and a piece of your own writing from this month.

  1. Imagine you're going to a winter camp. Write three sentences that each use a colon to introduce a list (clothes, food, games). Use the cover-up test on each.
  2. Write one list sentence that does not need a colon.
  3. Now take your own writing. Edit it five times, one row of the checklist each time. Use a different coloured pencil for each pass if you have them.
  4. At the bottom, write: The mistake I made most was ______. Next time I will ______.
  5. Share your goal with a grown-up.

For parents and teachers

Big idea (B3.3, D2.6, A1.2): The Grade 5 curriculum asks students to use colons for introducing a list after a complete sentence, and to edit drafts for spelling, punctuation, grammar and format. Reflecting on their most common mistakes and setting a goal builds the metacognitive skills in Strand A.

How to help at home:

  • Write a packing or grocery list sentence together with a colon, and do the cover-up test.
  • When editing homework, use the checklist one row at a time rather than "fixing everything" at once.
  • Ask your child what their personal editing goal is, and check just for that.

Common difficulties:

  • Colon after a verb (The winners are: ...). The cover-up test catches it.
  • Capitalizing the first list item after a colon. Not needed unless it's a proper noun.
  • Inconsistent list commas. Whether or not they use a comma before and, they should be consistent.
  • Editing fatigue. Five short passes are better than one long one.
