Start this activity with: What do you notice? What do you wonder? 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? Students try to approximate the…
Students use the National Weather System chart to gauge wind chill, examine the patterns that correlate increasing wind and/or decreasing temperatures, use wind chill numbers to estimate possible wind and temperature factors, and generally become familiar with this sort of interpolation and calculation.
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.
