Weather extremes


In the United States, the summer of 2012 was the warmest summer on record.  The winter of 2013-2014 is on the way to becoming the coldest winter in history. 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.
