Are we teaching interesting and engaging ways to represent data? Are we representing real data that is interesting and engaging with graphs?

Have you seen this?

.

When did the world’s population reach 1 billion? 2 billion? 3 billion?… (you see where I’m going, right?)

Can we graph this data to see if there is a pattern? Will the pattern from the data be similar to the graph in the BBC video above? Can we find a mathematical function that will mathematically model the data? Can the mathematical model find or predict:

How many people had been alive on the day you were born?

How many people were alive on your birthday?

When will the earth’s population reach 8 billion? 9 billion?

What questions will our learners have? Can we team with others to develop integrated studies lessons? What intriguing driving questions can we craft to facilitate learning and questioning with our learners?

This is really cool. I saw the site, but I didn’t think about all the cool mathematical modeling that could be done by taking sampling birthdays from some family members.

We could connect this to the Age Estimation lesson. Learners could collect population data from their parents, grandparents, and a group of their teachers.
