Theoretical and experimental probabilities are investigated using
an ExploreMath activity in which darts are randomly thrown at
Using an ExploreMath activity, slope is investigated in the context
of roofs and handicap ramps.
Exponential functions are introduced with a paper-folding activity
in which students create scatterplots, predict models, and assess
appropriateness of models. Students then use an ExploreMath activity
to further investigate exponential functions.
In this ExploreMath activity students are asked to investigate
the path of golf balls on a miniature golf course and describe
the path using functions involving absolute value.
Students investigate golden rectangles, and graph and analyze
data collected by measuring sections of their index fingers. This
activity is designed to be an introduction to the Least Squares
Fit Line Activity found on ExploreMath.com.
Using a tracing paper activity and the ExploreMath website, this lesson
focuses solely on the concept of period. Students explore the meaning of
period, periodic graphs including the graphs of the sine and cosine functions,
and the effects of the variable b in the sine equation, y = sin(bx).
Polar coordinates are introduced as students investigate the
bearings on a map of Charlottesville, Virginia. Students further
investigate polar coordinates using an ExploreMath activity and
convert coordinates of points between coordinate systems.
