Lesson 1: Introduction to Calendars

Duration: 50 minutes

Grade: 3

Class Size: 25 students

Curriculum: British Columbia Mathematics Curriculum

Curricular Competency Alignment

Big Ideas:

• Time is a way to describe and sequence events and the passage of moments.
• Calendars provide a systematic way to represent time and plan for events.

Curricular Competencies:

• Develop, demonstrate, and apply understanding of time to solve everyday problems.
• Use tools and strategies to represent and describe time, including calendars.

Content:

• The calendar year is divided into months, weeks, and days.
• Understanding units of time and their relationships (e.g., 7 days in a week, 12 months in a year).

Learning Objectives

By the end of this lesson, students will be able to:

1. Identify and describe the main components of a calendar (year, months, weeks, and days).
2. Demonstrate understanding of the sequence and duration of months and weeks in the calendar.
3. Create a personal calendar marking important dates such as their birthdays and other events.
4. Communicate their understanding of how calendars help organise and plan time.

Materials Needed

• Large wall calendar (12 months, colour-coded)
• Individual blank monthly calendar templates (one page per student)
• Coloured pencils, markers
• Stickers (stars, dots) to mark special days
• Visual timetable/chart showing days of the week and months of the year
• Whiteboard and markers
• Dyslexia-friendly printed handout with calendar vocabulary (months, weeks, days, etc.) in large print and clear fonts
• Projector or interactive whiteboard (optional) for calendar demonstration
• Scissors and glue (for extension activity)

Lesson Breakdown

1. Introduction and Engagement (10 minutes)

• Warm-up Discussion:
  Ask students: “How do we know what day, week, or month it is?”
  Engage with examples of what they use at home or school to keep track of days/events (e.g., school timetable, birthday reminders).

• Show the large wall calendar and introduce the key parts: year, months, weeks, and days.

• Use the interactive whiteboard/projector to highlight current month and days of the week.

• Dyslexia-friendly Strategy:
  Present a handout with calendar vocabulary using clear fonts and visual supports to reinforce terms.

2. Teaching & Modelling (15 minutes)

• Explain:

  • A year has 12 months.
  • Each month has about 4 weeks.
  • Weeks have 7 days each.

• Use physical month cards and arrange them in order on board/wall to visually show sequence.

• Highlight “Today’s date” and talk about how counting forward or backward works on calendars.

• Model:
  Demonstrate how to mark special events on the calendar (birthday, holidays).

• Use a volunteer’s birthday as an example.

3. Guided Practice - Create Your Personal Calendar (15 minutes)

• Each student receives a blank monthly calendar template (focus on current month for simplicity).

• Ask students to:

  • Write their birthday and mark it with a star sticker or coloured mark.
  • Add two more important events (e.g., family event, school event).

• Teacher circulates, helps with spelling, numbers, and placement.

• Students share one event from their calendar with a partner.

4. Independent Thinking & Extension (5 minutes)

• Provide an extension activity for advanced learners:

  • Create a mini yearly calendar collage by cutting out month names and arranging them on a large poster, including one personal event for each month (extension provided separately as take-home or in-class).

• For those needing support:

  • Offer 1:1 reading assistance with calendar vocabulary and simplified templates.

5. Conclusion and Reflection (5 minutes)

• Recap key points by asking:

  • What makes up a calendar?
  • Why is it helpful to mark birthdays and events on a calendar?

• Collect feedback through thumbs up/down or a quick verbal round.

• Briefly preview next lesson: understanding days, weeks, and how to read dates.

Assessment & Evaluation

• Formative Assessment:

  • Observe student participation during discussions and calendar creation.
  • Review their personal calendars to check understanding of dates and event marking.
  • Listen during partner sharing to evaluate comprehension and vocabulary use.

• Summative Opportunities (in later lessons):

  • Extended calendar-related tasks assessing use of weeks and months in problem-solving.

---

Adaptations for Diverse Learners

• Dyslexia-Friendly:

  • Use dyslexia-friendly fonts/large print handouts.
  • Allow oral responses or drawing symbols to represent events if writing is difficult.
  • Use multi-sensory materials: stickers, colours, and physical month cards.

• Advanced Learners:

  • Encourage creating yearly calendars with more events.
  • Introduce concepts of leap years or cultural calendars briefly as enrichment.

---

Teacher Reflection Prompts

• Did students engage with the calendar visuals and hands-on activities?
• Were the dyslexia-friendly strategies effective in supporting all learners?
• How did the personal relevance of marking birthdays impact motivation?
• What adaptations could enhance the next lesson on days and weeks?
