In this short activity, students learn the meaning and history of Labor Day as they look for patterns emerging from the Labor Day dates over the past years. Students then use those observed patterns to predict future dates of the holiday.

Back to school spending is huge and students might not appreciate what it costs to send them back to, essentially, their job of learning. In this activitiy students decide what equipment and supplies are necessary, estimate how much that will all cost, confer with groups or partners to refine their lists, and then research to find out more accurately how much it will probably cost to send them back to school. This activity could be used for students in upper elementary school all the way to high school. It offers an opportunity for kids to get estimating, researching, reasoning, calculating and communication skills honed for the coming year.

Let your students play this great game online at Ghost Whisperer Crystal Ball and

- Figure out why it works.
- Construct viable arguments
- Critique the work of others

This activity can be used with any grade level elementary through high school. Younger students might work with patterns, multiples and order of operations. Older students might work with systems of equations to prove how the Ghost Whisperer works.

There must be a lot of Olympians who haven't brought home medals. Probably most of the athletes that went to Rio didn't win anything. We couldn't find any data about this. Can you deduce it?

In this activity students try to calculate data that ** hasn't been publicized** by combining and sorting through information that

Which data is important and which is not?

How many athletes have come home from the 2016 Summer Olympics empty-handed?

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 their own state.

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