This Internet Mathematics Excursion is based on E-example 6.3.2
from the NCTM Principles and Standards for School Mathematics. This is
the third in a sequence of four lessons designed for students to
understand scale factor and volume of various rectangular prisms. In
this lesson, the student can manipulate the scale factor that links two
three-dimensional rectangular prisms and learn about the relationships
between edge lengths and volumes.

This lesson presents two classic problems (
Mangoes Problem and
Sailors and Coconuts)
that can be represented and solved in several different ways.
Middle-grades students work in groups on the problems to promote
communication of mathematical ideas, and a variety of classroom
solution attempts are described. This lesson plan was adapted from an
article, written by Jerry Stonewater, which appeared in the
November‑December 1994 issue of
Mathematics Teaching in the Middle School.
3-5
Students participate in an activity in which they develop number sense in and around the shopping mall. They develop their skills in determining percents and estimating area.

Students participate in an activity in which they develop number sense in and around the shopping mall. They solve problems involving percent and scale drawings.

In this lesson students explore the concept of orbits, focusing on
altitude, velocity, and distance traveled. The lesson explores the
connection of Earth-orbiting satellites to the study of the
environment. Both geometric and algebraic concepts are presented to
students in this application of science and mathematics to a real-world
situation.

Students investigate properties of perimeter, area, and volume related
to various geometric two- and three-dimensions shapes. They conjecture,
test, discuss, verbalize, and generalize patterns. Through this process
they
discover the salient features of the
pattern,
construct understandings of concepts and relationships, develop
a language to talk about the pattern,
integrate, and
discriminate
between the pattern and other patterns. When relationships between quantities in
a pattern are studied, knowledge about important mathematical relationships and
functions emerges.
6-8
Students explore the relationships among lines, slopes, and
y-intercepts
in the context of printing their algebra textbooks. Students use a
spreadsheet to facilitate their exploration. This activity is based on
an idea from
Navigating Through
Algebra in Grades 6-8 (NCTM, 2001).
6-8
Students use Venn diagrams to represent the relationships between the factors or products of two numbers.
6-8
Students make connections and expand on what they have learned in the first three lessons. Students explain the effects of different moves on the game board. Finally, students "Guess My Number" using various clues.
