Great introduction for students on scatter plots. Not only helps them understand the math content, but helps them understand the application and how it's relevant to every day life.

# data[].attributes.body
It's very interesting, and covers a wide range of topics, such as inflation, economy, food access, fast food.

The Math contents that related to this activity are bar graph, estimating values, percentages, percentage increase, averages/means, data collection methodology, proportional reasoning.

Wishing you could remember what they learned last year

What is meant by measure of center, how they compare to one another, and when to use each.

# data[].attributes.body
I wish students would have more opportunities to share qualitative observations when comparing two data sets. If they can describe what they see, it would be easier to frame vocabulary and use the numbers to explain their observations.

Understanding that data can be skewed

It seems like 6th grade always covers quite a bit conceptually without it being a large percentage of the curriculum. I wish maybe the idea of statistical questions and measures of center were covered in 4th or 5th grade. I think it would help focus on variability and distribution more in 6th grade.
