Use the open number line and our lists of temperature extremes to make signed number operations and absolute value sensible. Students compare record high and low temps (integers) and use absolute value in order to always find the positive difference. Subtraction of negatives becomes obvious in this lesson.
We have tons (well, 16) of activities to bring to your class in this last week before the holiday break. Movies, science, art, cooking, economics, weather and the logic of calendars. Enjoy!
Students use the National Weather Service’s chart to look for patterns, make predictions, decide how many ways the wind-chill could be -22 degrees F, and compare the formula’s outcome with their chart predications.
Sts learn a little history, question what they have learned earlier, and calculate how far off Columbus was from East India and his understanding of the actual circumference of the Earth.
We have 16 interesting activities to bring home; air quality, erosion, water levels, climate change, solar power, recycling, and changes to our Earth. Use the moment.
Combine colorful and cool fall hiking with a little mathematics about percent grade change. What is a steep grade? Why is it in percent? How does grade change relate to slope?
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…
NASA and SpaceX plan to launch humans from Kennedy Space Center, Florida, to the International Space Station for the first time since July 11, 2011. This is a more current events activity than mathematical.
Last week millions of people marched in hundreds of countries worldwide to demand “climate justice”. Greta Thunberg speaking at World Economic Forum 2018 Choose from any of our 14 activities to let students quantify some of the results of climate…
Geometry Activities with a wow factor! Elementary grade activities Expressions, equation and systems of equations Artful Math Data and probability Number sense Weather Two variable relationships (linear, exponential etc) Coronavirus related activities Ratio, proportion, percent Summary activities
In the travel section of our newspaper this week, Wiltshire, England was a recommended destination to see Stonehendge and crop circles ……….. crop circles? Many of the crop circles in England appear mysteriously overnight. They are often huge but appear…
On Thursday evening Leslie and Brian spoke at Boston College as part of the ATMIM (Association of Teachers of Mathematics in Massachusetts) Winter Conference. Our presentation was on making mathematics meaningful to students. We shared, did and discussed math activities…
