Beginning to understand the relationship between change and accumulation
is a precursor to understanding calculus. This example illustrates the
use of dynamic graphs to learn about change and linear relationships, as
described in the Algebra Standard.
This three-part example illustrates the use of iteration, recursion, and
algebra to model and analyze the changing amount of medicine in an
athlete's body. This example is adapted from High School Mathematics at Work ,
a publication from the National Research Council (1998, p. 80). These
Using interactive figures, students can investigate how changing the
height of a rectangle with a fixed width changes its area. As discussed
in the Number Standard ,
understanding multiplication by fractions and decimals can be
challenging for middle-grades students if experiences with
Students develop an understanding of how to justify geometric relationships in a technological environment, as described in the Geometry Standard .
This example allows students to explore
three methods for measuring how well a linear model fits a set of data
points. The Data Analysis and Probability Standard calls for students to
explore how residuals (the difference between a predicted and observed
value) may be used to measure the "goodness of ...
