Because of climate change, we've been having too many extreme weather events. There have been unusual droughts and heat in the West, an increased number of hurricanes, severe flooding, and high winds throughout the midwest.
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.
