# Calendar Sorting

## Calendar Sorting

Do you know those calendars that are a series of cards, one for each month?
I have one of those on my desk at home.

The cat jumped on my desk while I was at school yesterday and knocked it off on to the floor.
Now they are all muddled up.
I do not know which month is which and I don't know how to put them back in the right order.
Can you help?

Here is a sheet you can print off and cut up into twelve cards, one for each month.

Can you put the cards in the right order?

#### Why do this problem?

This activity will help learners become more familiar with our calendar.  In particular, the task will reinforce the order of months in a year and the number of days in each month.

#### Possible approach

Introduce the task by telling the story about your cat jumping on to your desk and knocking the calendar onto the floor (or something similar).  You need the class' help to sort out the calendar cards.

It would be a good idea to say little else at this stage.  Give pairs or small groups a copy of the cards and give them plenty of time to have a go.

You may like to draw everyone back together for a class sharing of ideas (mini plenary) when you judge they have had enough time exploring. Some learners may be stuck and need some help to see how to move forward. Others may benefit from needing to articulate their ideas.  You can then give them more time to continue with the task.

Each pair/group could make a poster about the task, explaining how they went about it and then sticking down the cards to show the final solution.

#### Key questions

How might you start?
What do you know about the number of days in each month?

#### Possible extension

For an extra challenge, why not give children the cards from these sheets which are the months from a three-year calendar.  This time, they have to sort them into the three consecutive years, month by month.

#### Possible support

It might help to have several current calendars available so children can remind themselves of its structure.
