Back to school

In this investigation students calculate the percentage of the U.S. population (current and historically) that are enrolled in K-12 schools. They are asked to draw conclusions from these variations. Finally, they use their calculations to predict the number of enrolled students in Massachusetts.

A calculation of percent increase (or decrease) of earning power compared to education level is the final activity in this study.

Should I buy the BIG one?

Clicking on this image will show it larger in a new window.

 Let your students decide if the BIG one is a fair deal.  Click on the pic to enlarge and post on the wall.  Have kids a pick a sandwich.  Which size will they get?  Which size is a better deal?  Make a guess, then do the math…

Ebola is a deadly virus that has reappeared in Western Africa in an outbreak that began in February of this year.  We’ve supplied you with weekly statistics on the progression of this disease and given you and your students a few questions to assess.

Consider beginning this task by finding out what students already know about Ebola and viewing the slide show from HealthMap.org/ebola/.

In the Cloud

Clouds
I want to find a way to keep my photos, documents, videos and music in a place that is safer then on my computer.  If my Macbook Air melts, where can I keep my irreplacable files so that they aren’t lost?

Should I buy some iCloud space?  I found that I could get 5GB of storage free at iCloud.  Is that enough for my files?  Should I instead buy 10, 20, or 50 GB?

At Flikr I can get 1 TB of space free.   What on Earth is a TB?  How should I save my files?

In this activity students learn about computer memory, KB, MB, GB and TB.  They compare four different cloud providers and estimate their own cloud storage needs.

Bring a little art into your math class as you begin to use the Pythagorean theorem and your students first meet irrational numbers.

Immigration numbers

Use our data to do some analysis about the issues and changes in immigration policy and numbers.  This could be a very interesting day of mathematics.
