Action
Comparing similar groups
We can use what we already know about one group to make a prediction about another similar group.
For example, we can make a prediction about two months in a year.
The months we pick must have the same number of days.
Therefore, we will use June and November as they both have 30 days.
June
Explore the June calendar:
- It starts on Tuesday, June 1st, 2021.
- It ends on Wednesday, June 30th, 2021.
- All Mondays are circled. The Mondays are the 7th, 14th, 21st, and the 28th.
- The calendar has the columns from Sunday to Saturday across the top.
- The numbers 1 through 30 are filled in.
Select the correct answer.

Use the June data above to predict how many Mondays there are in November.
Here are some sentence starters to help:
- I predict that there will be…Mondays in November
- My prediction is that…
- I predict that…
- I predict that November will have…
Record your ideas in your notebook or another method of your choice.
Press ‘Show prediction’ to reveal a possible November prediction.
I predict that there will be four (4) Mondays in November. I am using what I know about another month of 30 days (June) to make a prediction about November. There are 30 days in November, which means these two (2) months are similar.

November
Explore the November calendar, and check your prediction:
- The calendar has the columns from Sunday to Saturday across the top.
- The numbers 1 through 30 are filled in.
- The month starts on Monday, November 1st, 2021.
- The month ends on Tuesday, November 30th, 2021.
- All the Mondays are circled. The Mondays are the 1st, 8th, 15th, 22nd, and the 29th.

Predictions
If your November prediction was not correct, why might that be?
Compare June and November and try to find a difference between them.
Record your ideas in your notebook or another method of your choice.
Press ‘Show results’ to reveal a difference between June and November.
When we compared the two calendars, we found that the first (1st) day of June was on Tuesday, but the first (1st) day of November was on a Monday.
This might explain why the number of Mondays was different between the two months.
