Hi. I recently used this lesson for a unit on Probability for Year 7. Though instead of the cards of famous mathematicians, I used the recent promotion in Coles Supermarkets for Little Treehouse Books. If you spend $30 you can have a little book that comes in a package. There are actually 24 in the set, and Coles claims to have provided an equal number of each, randomly distributed throughout their supermarkets. To simplify the problem, we assumed a collection of 6 books. just like the lesson. I had each student complete the trials ten times. They populated a prepared whole class spreadsheet (Google Sheets) with their results. This produced a histogram that took shape while this happened. Next, we produced a scatterplot based on different sized collections. Students could pick whatever size they liked, and we used the random integer generator on their calculators to conduct the experiments. This lesson took place online in remote-learning during the corona-virus pandemic. By the end of the lesson, we had two lovely graphs to look at and discuss. I share the spreadsheet here. Feel free to make a copy. https://docs.google.com/spreadsheets/d/1dAQGVY2nTmwWOTDCIA2C-pm_6LcWGjAX5teoALig-XU/edit?usp=sharing

p.s. I meant to add that the spreadsheet can take up to 30 students. And one sheet is hidden (this sheet makes the histogram possible). It would be great if software could be developed for this lesson.

Thank you for sharing Damian. That is what I love about maths300 lessons, you can add in your own authenticity to create successful and engaging lesson.
