Ups and Downs
·
Students
investigate growth over time within a variety of contexts. They create and use line graphs to represent
continuous processes that occur over time.
The term linear growth is
used.
·
Students will
recognize and use linear growth by looking at the differences in a table;
looking at the graph, which is a straight line; or looking at the formula that
describes the situation. Both recursive and direct formulas are used.
·
Students
investigate quadratic growth. They investigate second differences in a
table. They use quadratic formulas that
describe quadratic growth within this context.
Students are introduced to exponential
growth.
·
Students are
introduced to the terms cycle and period to describe features of a
periodic phenomenon. Periodic graphs are
investigated.
·
Growth factors
between one and zero are used to describe exponential decay in real life
situations. The relationship between
percents and fractions is applied.
