In this grades 9–12 activity, students write and solve a system of
linear equations in a real-world setting. Students should be familiar
with finding linear equations from 2 points or from the slope and
y-intercept.
Graphing calculators are not necessary for this activity, but could be
used to extend the ideas found on the second activity sheet. Parts of
this lesson plan were adapted from the October 1991 edition of
Mathematics Teacher.
9-12
Students will collect information about the National debt, plot the data by decade, and determine whether an exponential curve is a good fit for the data. Then student groups will determine and compare common traits and differences in changes in the National debt in three major eras: the Civil War, World War I, and World War II.
