Use calendars to locate specific dates, identify the day of the week and determine a date 2 weeks before or after a given date.
Chapter 12 • AC9M2M03
Develop Year 2 calendar skills through practical activities for locating dates, identifying days of the week, counting days between events and finding dates before or after a given day. This parent-friendly guide supports children in reading, creating and using calendars before completing the printable activities aligned with Australian Curriculum code AC9M2M03.
In this unit, children identify dates and determine the number of days between events using calendars.
Children learn to use the structure of a calendar to:
Calendar activities help children connect number, addition, patterns, days, weeks and months with real events in their everyday lives.
These activities support Australian Curriculum Version 9.0 content descriptor AC9M2M03 and its associated elaborations.
Identify the date and determine the number of days between events using calendars.
Use calendars to locate specific dates, identify the day of the week and determine a date 2 weeks before or after a given date.
Create a class calendar and record relevant dates such as birthdays, school assemblies, sports carnivals and class excursions.
Use addition and calendar information to calculate how many days remain in the current month and in the remaining months of the year.
Identify and locate specific days and dates such as school holidays, sports days, ANZAC Day, Easter, Diwali and Ramadan.
Children can use these patterns to move forwards or backwards, locate events and calculate the number of days between dates.
Important calendar relationships include:
Children should use an accurate calendar for the selected year, as the day of the week for a date changes from year to year.
Children will learn to:
I can locate a date on a calendar.
I can identify the day of the week for a date.
I can find a date one week before or after.
I can find a date two weeks before or after.
I can count the days between two events.
I can explain whether I counted the starting day.
I can record an event on a calendar.
I can create a class or family calendar.
I can count the days remaining in a month.
I can add days across different months.
I can locate important days and events.
I can explain how I solved a calendar problem.
Teachers build calendar understanding by connecting dates with familiar events and using real monthly and yearly calendars.
At home, follow this sequence: locate the month, find the date, identify the day, move forwards or backwards, count and explain.
Begin with a monthly calendar and identify:
Use an accurate calendar for the year being studied. A date may fall on a different weekday in another year.
Practise saying the days in order:
Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday.
Ask children to identify:
Practise saying the months in order:
January, February, March, April, May, June, July, August, September, October, November and December.
Ask:
Ask your child to locate a date such as 18 March.
Encourage children to state the complete result:
“The event is on Tuesday 18 March.”
Once the date has been located, follow its calendar column to the weekday heading.
Ask:
To find the next date, move one square forwards.
Children should recognise that the date number increases by one.
At the end of a row, continue at the beginning of the next row.
At the end of a month, continue to the first date of the next month.
To find the previous date, move one square backwards.
The date number decreases by one unless the movement crosses into the previous month.
Use a two-month calendar when practising dates that cross a month boundary.
One week contains 7 days.
On most monthly calendars:
The weekday remains the same.
For example, if an event is on a Wednesday, one week later will also be a Wednesday.
Two weeks contain 14 days.
Children can:
The date two weeks before or after should fall on the same day of the week.
Mark the starting event and ending event on the calendar.
Move one day at a time and count each move.
For example, from Monday to Friday:
There are 4 days between Monday and Friday when counting elapsed days from the starting point.
Calendar questions may use different counting conventions.
Ask whether the problem is asking:
Children should explain what they counted rather than relying on an unexplained number.
Use a pointer, counter or pencil mark to move through the end of one calendar row and into the next.
Children should continue the weekday sequence without restarting the count.
Place two consecutive monthly calendars beside each other.
Begin at the starting date, count the remaining days in the first month and continue into the next month.
Record the calculation in parts.
For example:
Begin with a blank monthly calendar.
Add:
Use short, clear labels so the calendar remains easy to read.
Children can use symbols or colours to represent different event types.
For example:
Add a simple key explaining each symbol.
Use the completed calendar to ask:
Locate today’s date and identify the final date in the month.
Count the days after today to the end of the month.
Decide whether the current day is included and state the counting rule clearly.
Children should notice that months do not all contain the same number of days.
Use a yearly calendar to identify:
Use the actual calendar year shown rather than relying only on memorised rules.
Break the problem into smaller parts.
A table can help organise the information.
| Month | Days Included |
|---|---|
| Current month | Days remaining |
| Next month | Full month |
| Following months | Full months |
Calendar calculations can be represented using addition.
For example:
days remaining in the current month + days in the next month + days in later months
Children should write the separate parts before finding the total.
Use the school calendar to locate:
School dates differ between states, territories and schools, so use the calendar supplied by the child’s school.
Use a current calendar to locate events such as ANZAC Day and other national or community occasions.
Ask children to identify:
Calendars may include cultural and religious events such as Easter, Diwali or Ramadan.
Some event dates vary from year to year, and some observances may extend over several days or weeks.
Use an accurate calendar and respectful, trusted information when discussing the event.
Avoid assuming that every family observes the same events. Invite children to share calendar events that are meaningful to their families and communities.
Ask children to compare two events.
Calendars contain useful number patterns.
Ask children to use these patterns rather than counting every square from the beginning.
Cover several dates on a calendar and ask children to determine the missing numbers.
They can use:
Encourage children to verify their answers by:
A complete answer should usually include the day, date and month when these details are requested.
Instead of writing:
14
write:
“Two weeks after Monday 3 June is Monday 17 June.”
The date is the numbered position in the month. The day is the weekday name, such as Tuesday.
Trace directly upwards from the date to the weekday heading.
One week contains 7 days, so move down one row or add 7.
Build two groups of 7 days to show that 2 weeks contain 14 days.
Use a counter or pointer and continue at the beginning of the next row.
Place consecutive monthly calendars beside each other and continue the same count.
Ask whether the task involves elapsed days or all included calendar dates.
Check the final numbered date shown on the actual calendar.
Check the year printed on the calendar because weekdays change from year to year.
When calculating days left in the year, begin with the days still remaining in the current month before adding full months.
Decide at the beginning whether today is included and keep the same rule throughout the calculation.
Use an accurate calendar for the selected year because some observances vary annually.
Locate today’s date on a calendar and state the complete day, date, month and year.
Then find yesterday and tomorrow.
