The interactive paper pool game in this i-Math investigation provides an opportunity for students to further develop their understanding of ratio, proportion, and least common multiple.

Students develop a delicious new drink by mixing various concentrations of a two-fold dilution series. Students calculate the percents of their mixtures, taste these differences, and visually observe their results.

Use this
activity to practice how to enter a set of data, plot the data on a coordinate grid, and determine the equation for a line of best fit.9-12
Sea gulls and crows feed on various types of mollusks by
lifting them into the air and dropping them onto a rock to break open
their shells. Biologists have observed that northwestern crows
consistently drop a type of mollusk called a whelk from a mean height of
about 5 meters. The crows appear to be selective; they pick up only
large-sized whelks. They are also persistent. For instance, one crow was
observed to drop a single whelk 20 times. Scientists have suggested
that this behavior is an example of decision-making in optimal foraging.

Interactive computer-based tools provide students
with the opportunity to easily investigate the relationship between a set of
data points and a curve used to fit the data points. As students work with
bivariate data in grades 9-12, they will be able to investigate relationships
between the variables using linear, exponential, power, logarithmic, and other
functions for curve fitting. Using interactive tools like the
one below, students can investigate the properties of regression lines and
correlation.
