Syntax and Sentence Structure
Colons: From Grocery Lists to Formal Letters

Summary

In this literacy centre, designed for grades 4 to 6, students will learn how to use colons in practical, real-life situations. From writing a grocery list to composing formal letters and even creating scripts for a class play, they will see how colons clarify information and create structure. Students will also write a script using colons to introduce dialogue in scripts.

Learning Outcomes

By the end of this centre, students will be able to:
  • Use colons to introduce a list after a complete sentence;
  • Use colons appropriately in formal letters and memos;
  • Apply colons in scriptwriting to introduce dialogue.

Material to Prepare

  • Appendix A: Scenario Cards
  • Appendix B: Colon Challenge Worksheet
  • Appendix C: Script Template
  • Pencils, paper, and optional props for script activities.

Procedure

Introduction for Students:
We use colons everywhere and everyday, even if we don’t always notice them! In this centre, you’ll learn how to use colons to make lists, write formal letters, and create scripts. This will help you see why colons are so important in communication.
Section 1: Using Colons in Lists

Situation: Imagine you’re helping a friend prepare for a class event. They have a lot of tasks to complete, but their to-do list is a mess. Your job is to rewrite the list using a colon after the introductory sentence so that it’s clearer and more organized.

  • Example:
    We need several things for the event: balloons, posters, snacks, and name tags.
  • Activity:
    1. Students will receive Scenario Cards that describe tasks or errands (e.g., grocery lists, packing lists for a trip).
    2. They must rewrite the scenario using a colon to introduce the list correctly. For example:
      • Original: For the trip, you must pack sunscreen, a hat, snacks, and a water bottle.
      • Corrected: You’ll need to pack the following for the trip: sunscreen, a hat, snacks, and a water bottle.

Section 2: Colons in Formal Letters

Situation: Imagine you’re writing a formal letter to request permission for a class field trip. To make your letter look professional, you need to write a proper opening with a colon in the salutation.

  • Example:
    Dear Principal Smith:
  • Activity:
    1. Provide students with a formal letter template that includes spaces for them to fill in their own names, dates, and reasons for writing the letter.
    2. They must write the salutation using a colon and then complete the body of the letter. They can choose a purpose, such as requesting permission for a field trip or thanking someone for a donation to their class project.

Section 3: Colons in Scripts

Situation: You and your classmates are writing a short play about preparing for a school event. As the scriptwriter, you must use colons to show who speaks in the play.

  • Example:
    Narrator: The story begins with students rushing to decorate the school for the event.
    Teacher: Can someone please bring me the box of decorations?
  • Activity:
    1. Using the Script Template, students will create a short script (about one page), using colons to introduce the dialogue for each character.
    2. To inspire their script, provide students with a fun scenario (e.g., setting up for a class party or preparing for a school play). They can choose characters, write short lines for each, and use colons to indicate who is speaking.

Section 4: The Colon Challenge
  • After completing the tasks, students will participate in the Colon Challenge. They will:
    • Receive a series of sentences that need colons added.
    • Rewrite the sentences using colons to introduce lists in a letter’s salutation or in a script.
  • Example Sentences:
    • Here’s what we need for the class project pencils markers glue sticks and scissors.
      (Correct: Here’s what we need for the class project: pencils, markers, glue sticks, and scissors.)
    • Dear Ms. Turner
      (Correct: Dear Ms. Turner:)

DIFFERENTIATION: Observing and providing support during analysis.

Possible Observation Intervention Strategies
Students struggle to recognize when a colon should be used to introduce a list (e.g., after a complete sentence).
  • Remind students that a colon should only follow a complete sentence. Provide examples and non-examples, showing sentences that are not complete and how adding information before the colon fixes this (e.g., Bring the following: pencils, paper, and notebooks vs. Bring: pencils, paper, and notebooks).
  • Give students a series of sentences with incomplete thoughts before the colon and ask them to revise the sentence so that the colon follows a complete sentence.
Students are unsure about when to use colons in formal letters, especially for salutations.
  • Show students a variety of formal letters (e.g., business letters, emails, memos) where colons are used after salutations (e.g., Dear Principal Parker:). Review that colons in salutations are formal, while commas are used for informal letters.
  • Have students write their own formal letter for a real or imagined scenario, ensuring they use a colon after the salutation. Provide templates or examples to guide them.
Students are placing colons in the wrong places in scripts or dialogue (e.g., placing colons within a sentence instead of after the speaker’s name).
  • Engage students in a role-playing activity where they act out a dialogue. As they practise, they must write out the script using colons correctly before the speaker’s name (e.g., Teacher: Please get your notebooks ready).
  • Walk students through writing a dialogue together as a class, ensuring that they use colons after each character’s name. Have them practice with simple dialogues before moving on to their own creative scripts.
Students confuse colons and semicolons, using them interchangeably or in the wrong context.
  • Create a side-by-side comparison of colons and semicolons, with examples showing their proper uses (e.g., Colon: introducing a list vs. Semicolon: linking two related independent clauses).
  • Provide students with pairs of sentences, some requiring colons and others needing semicolons. Ask them to choose and apply the correct punctuation and explain why they made their choice.
Students complete tasks quickly and need additional challenges.
  • Challenge advanced students to write a more extended script for a class play, where multiple characters interact and dialogue is more complex. They can focus on integrating colons for dialogue and other punctuation (e.g., commas, quotation marks).
  • Encourage students to create more detailed lists with colons that include additional details or descriptions. For formal letters, ask them to write letters with multiple purposes (e.g., both thanking and requesting something) to practise varied sentence structures.
