Step 1: Watch this video which is about the story of 365 Penguins. In the book 365 Penguins, the family received a new penguin each day. They received their first penguin on January 1st and this pattern continued throughout the entire year.
Step 2: Let’s brainstorm…
– How many days in a week?
– How many months in a year?
– How many days in a year?
– How many days in the year 2020?
– What do we call a year with 366 days?
Step 3: Now let’s look closely at the 2020 calendar. If we had to receive a penguin daily, starting from January 1st, how many penguins will we have by the end of February? How many ways can you find to show this using cups? Show the different options on a mini whiteboard. Use cups/caps/blocks/popsicle sticks to present your answers using arrays as shown in the pictures below.
Step 4: Let’s look at the 2020 calendar once again. How many penguins will there be in the months of July and August? Is this an odd or an even number? How many ways can you find to show this using cups? Show the different options on a mini whiteboard.
Step 5: Now you need to calculate. How many penguins will there be on the last day of June 2020?
Step 6: On what day did the family receive its 40th penguin? How did you work this out?
Step 7: Can you create your own question related to calendars?
Step 8: To practice further you can work out this sheet which includes various task cards related to the calendar. Furthermore you can find an this document which includes questions that have featured in past Mathematics Annual papers. An Answer Sheet is also included.
