The Olympic Torch trip in South Korea

On October 24, 2017, the Olympic flame was captured on Mount Olympus, Greece. (Lighting the Olympic Torch). That flame lit one of this year's Olympic Torches and the Torch relay was begun on its way to the opening Winter Olympic Ceremonies in PyeongChang, South Korea on February 9, 2018.

The Torch relay will last for 101 days, cover 2,018 kilometers, be carried by 7,500 runners, and travel by plane, helicopter, Turtle ship, foot, sailboat, robot, steam train, yacht, cable car and zip line.

Enjoy a mathematical divergence into world-class sport, South Korea, and the cooperation of Nations as your class appreciates unifying music, participation rates, metric conversions, and per person distances traveled.

Is this promo a good deal?

McDonald's was offering an "Arch Card" special deal. If you bought an Arch Card for $100 you were entitled to a free BigMac or EggMcMuffin every week for a full year. The card was only offered at some McDonald's restaurants and to a limited number of customers.

Was this a good deal?  And if you do get a free BigMac or EggMcMuffin every week what are the costs on your body?  How long will it take you to exercise those calories away? Let's do the math!


Martin Luther King, Jr. activities

Timelines for the life and work of Martin Luther King Jr. - Students create one of two timelines about Martin Luther King Jr's life or the efforts in America to create a racial balance in the U.S. 3.MD, 4.MD, 5.MD, 6.RP, 6.G,  7.RP, 7.G

Data on the National Mall sites - Two data analysis activities about the National Mall.

Who do we honor? - What people or events are included in the National Mall monuments? Students use fractions or percents to decide what they can notice about those we honor. 3.NF.1, 6.RP.3

Monuments most visited - Students analize the visitor statistics of the National Mall and make observations. 6.RP.3, 7.NS.3

Bears Ears Monument

There is some beautiful land in Utah that was just recently changed from federally protected land to mostly Utah overseen land.  What was the point of that?  Was the land needed to allow for population expansion or what?  Let your students examine the data and make their own conclusions.

Warning: This discussion could get politically active.

Below is our slide show of some of the beauty and ancient ruins of the original Bears Ears Monument. (Best viewed full screen.)

Cold and Snowy activities

How much snow is that? - How many inches of snow produced that pile?  How much snow in volume is on top of the car?  How much could that snow weigh? Approximation, snow/water equivalent rates (SWE) 5.MD.C, 6.RP.A, 7.RP.A, 7.EE.B, 7.G, 7.EE.A

Snowy days - Students make predictions of total snow fallen in a 23 hour period. average snow fall rates, graphing, slope analysis for a real event. 8.F.5 , 8.SP, HSF.IF.B.6 , HSF.LE.A.2 , HSS.ID.B.6

It sure is cold out ... or is it? - Correlation between place latitudes and average January temperatures is investigated. averaging, missing data for averaging, line of best fit, extrapolation 6.SP.5, 8.SP.1, 8.SP.2, 8.SP.3, HSS.ID.B.6, HSS.ID.C.7, HSA.CED.A.2,  HSF.LE.A.1

How much did the temperature change in Boston - Show students the graph with the text and let them determine and discuss the temperature change as a class.  How could they draw a diagram to help students see the correct increase?  What other temperatures could the low and high points have been to result in the same temperature swing? 6.NS.5, 7.NS.1, 7.NS.3

Days are getting longer

Clicking on this image will take you to to the University of Nebraska's astronomy simulation in a new window.

What's your guess?  How fast are the number of daylight hours changing each day?  Will the changes be dramatic or subtle?

Students make guesses; compute how long, on average, the change in daylight hours should be; play with a cool piece of comparison technology; and finally understand the variability in our year of daylight hours.
