• 30 min · Pairs

Birthday and Festival Hunt

Provide students with a full year's calendar. Ask them to mark their own birthday, their family members' birthdays, and important Indian festivals like Diwali, Holi, Eid, and Christmas. They can then calculate the number of months and days between these events.

Explain how to find a date that is 3 weeks after a given date on a calendar.

Facilitation Tip

Encourage students to discuss the different days of the week the festivals fall on this year compared to the last.

What to look for

Give students a calendar page for the current month and ask them to circle today's date, put a square around the date of the second Saturday, and find the day of the week for the 25th.

Activity 02

• Inquiry-Based Learning
• 25 min · Small Groups

Calendar Detectives

Give each group a calendar for a single month. Provide them with a worksheet of 'clues' to solve, such as 'Find the date of the third Tuesday' or 'What is the date 2 weeks after the 5th of this month?'.

Identify the number of days in each month of the year.

Facilitation Tip

Use a large classroom calendar to model solving the first clue together as a whole class.

What to look for

A short quiz with a calendar image and questions like 'How many Sundays are in this month?', 'What is the date 3 weeks after the 4th?', and 'Is this year a leap year? Why or why not?'.

Make Your Own Month

Give students a blank calendar grid. Announce a month and the day of the week on which the 1st falls (e.g., 'Let's make a calendar for August, which starts on a Thursday'). Students must correctly fill in all the dates for that month.

Analyse a calendar to find patterns, such as how many Sundays are in a particular month.

Facilitation Tip

Remind students to first recall how many days are in the given month before they start filling the grid.

What to look for

Provide a checklist for students with 'I can' statements, such as 'I can name all 12 months in order' and 'I can find the number of days in any month'.

A few notes on teaching this unit

Start with a large, physical classroom calendar. Model how to find dates and count weeks using a 'think-aloud' strategy. Use real-life examples, like finding the date of the next school holiday, to make the learning relevant. Progress from simple date-finding to solving word problems that require calculation.

By the end of these activities, your students will be able to read any calendar, calculate time periods in weeks, and even explain the special case of a leap year.

Watch Out for These Misconceptions

• All months have exactly 4 weeks.

  Only February in a non-leap year has exactly 28 days, which is 4 weeks. Show on a calendar that all other months have 30 or 31 days, which is 4 weeks plus 2 or 3 extra days. Count these extra days together.

• Confusing the number of days in different months, often assuming all have 30 days.

  Teach the simple 'knuckle mnemonic'. Make a fist: each knuckle represents a month with 31 days (Jan, Mar, May, etc.), and the space between knuckles is a month with fewer days (Apr, Jun, etc.), with February as the special case.

• When asked to find a date '3 weeks after' a given date, students count the starting day as part of the first week.

  Use a large calendar to physically demonstrate counting. Emphasise that 'after' means you start counting from the next day. A jump of one week means landing on the same day in the next row.
