# Lesson 102: Using calendars

🧮 MATH (40 Lessons) • 🟡 C. Shapes and Measurement

← Back to Level 1

## Objective

I can read a simple calendar to find days and dates and use today, yesterday, and tomorrow to talk about events.

## Materials

- One or more printed month calendars (real or teacher-made)
- Pencil or highlighters to circle special days
- Optional: sticky notes for birthdays, trips, and other events

## Mini-lesson — Reading a month calendar

A calendar shows the days and dates in a month and helps us see when events happen.

- The top shows the month name (March, April, May…).
- The first row usually shows the days of the week: Mon, Tue, Wed, Thu, Fri, Sat, Sun.
- Each little box has a number. That number is the date (1, 2, 3… 31).

Weeks and months

- 1 week is 7 days in a row (for example: Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday).
- On a calendar, 7 days in a row often sit in the same row (one full line of boxes).
- A month is longer than a week. It is usually about 4 weeks and a bit more.
- Most months have 30 or 31 days. One month, February, is shorter.

Today, yesterday, tomorrow

- Today is the date you are on right now.
- Yesterday is one day before today on the calendar.
- Tomorrow is one day after today on the calendar.

Using calendars for events

We can circle special days like a birthday, a skate lesson, or a trip. We read the month, the day of the week, and the date to tell exactly when something will happen.

In this lesson, look carefully at the month name and the number in each box. That tells you the date, so you can work out today, yesterday, tomorrow and 1 week later.

Calendar strip: Three months labelled A, B, C.

Calendar A — March (31 days)

Calendar B — April (30 days)

Calendar C — May (31 days)

## Guided Practice — Calendar walk and tracing

You will use a real calendar or a big printed month calendar on the wall. First, explore the days and dates. Then use the tracing pad to copy the most important words and dates.

1. Find today: Point to today's date on the big calendar. Say the month and date out loud (for example, "Today is March 10").
2. Find yesterday and tomorrow: Point to the date for yesterday and then the date for tomorrow. Say each date out loud.
3. Write your three dates: On your paper or notebook, write three lines:
   • today: (write the date) • yesterday: (write the date) • tomorrow: (write the date)
4. Use the tracing pad: Choose one day word (today / yesterday / tomorrow) and one date (for example, 10 or 21). Trace them on the tracing pad.
5. Draw a tiny calendar box: On the tracing pad, draw a small calendar box (a square with the date inside) and circle it to show a special day.

## Practice 1 — Drag & Drop: Calendar stories with month cards

Use the month cards to solve each calendar story. Drag the cards into the boxes in the correct order. Some questions use months, and some use event cards like “Birthday” or “Class trip”.

1) Put the three months in order from earliest to latest.

Use: March, April, May.

April May March

2) Amira's family has three events:

- Birthday on March 5.
- Class trip on April 10.
- Picnic on May 15.

Drag the event cards from first to last.

Picnic Birthday Class trip

3) Which month is in the middle of the three?

Drag the correct month card into the box.

March May April

4) Now put the months from the latest back to the earliest.

Use the three month cards again.

March April May

5) Spring break is on March 12. Which month card does it belong to?

April March May

6) Sports day is on May 20. Which month card do you use?

May March April

7) Which month cards show months that come after March?

Drag the months that are after March (left to right).

March April May

8) Which month cards show months that come before May?

Drag the months that are before May (left to right).

9) A library visit is on March 23. A class photo is on April 9.

Drag the months into the boxes from earliest to latest.

April March

10) Three events are written on the calendars:

- Movie night on March 18.
- Fun run on April 25.
- Family picnic on May 8.

Drag the event cards to show them from first to last.

## Practice 2 — Tap the calendars that match the clue

Each picture shows a small calendar with a month and a date. Read the clue, then tap the calendar or calendars that match. Some questions have more than one correct answer.

1) On a calendar, today is May 3. Tap the calendar that shows tomorrow's date.

2) On a calendar in April, today is April 10. Tap the calendar that shows yesterday's date.

3) The school trip is on June 15. Tap the calendar that shows the date that comes two days after the trip.

4) Your friend's birthday is on July 5. Tap all the calendars that could show a date that is one week later on the same weekday.

5) The month of August has 31 days. Tap the calendar that shows the last date of the month.

6) Today is Monday March 8. Tap the calendar that shows tomorrow's date.

7) A club meets every Wednesday. The first meeting is on September 3. Tap another calendar that could also be a Wednesday in that month.

8) You draw a heart on February 14 for a special day. Tap the calendar that shows the date that comes just before that heart.

9) In October, today is October 26 and the month ends on October 30. Tap all the calendars that show dates that are still left in the month (including today).

10) A calendar shows the month of March. Tap the calendar that could be the first day of that month.

## Practice 3 — Month timeline: Tap the correct month

Each timeline shows all 12 months of the year. Read the question, then tap the tick for the correct month.

1) Which month comes right after February?

2) Which month comes just before October?

3) Which month is the very first month of the year?

4) Which month is the last month of the year?

5) Which month is between June and August on the timeline?

6) A school trip is in April. Sports day is 2 months later. Tap the month for sports day.

7) A birthday is in November. The party is 1 month earlier. Tap the month for the party.

8) Summer camp is in July. Practice starts 1 month before. Tap the month for practice.

9) Winter holidays are in December. Tap the month that is 3 months before December.

10) A fun run is in May. Training starts 3 months earlier. Tap the month for training.

## Quick Check — Using calendars

Answer each question about months, days, and dates. You may look back at the calendars in the mini-lesson if you need help.

6 12 30
There are 12 months in one year.

2) Today is written as April 3. Which part tells the month?

3 3rd April
The word "April" is the month name.

3) Today is March 10. What is tomorrow's date?

March 11 March 9 March 20
Tomorrow is one day after 10, so it is March 11.

4) Today is written on the calendar as 15. Which date is yesterday?

16 15 14
Yesterday is one day before 15, so it is 14.

5) Which month comes after March?

February April January
The months go February, March, April, so April comes after March.

6) You circle a special day on May 8. What does the number 8 show?

The date The month The year
The number 8 tells the date, the day number in the month.

7) On a calendar, the first row of boxes after the day names usually shows:

Months Years The first dates in the month
Under the day names you see the first dates of the month (1, 2, 3…).

8) Today is Friday 22. Which day of the week will 29 most likely be?

Monday Friday Sunday
One week later is seven days later, so 22 + 7 = 29. It will also be a Friday.

## Exit ticket (student)

😀 I can read calendars and dates easily 🙂 I can read some calendar dates but still need more practice 😅 Calendars still feel tricky for me

#### Next time I will practise…
