Students will measure the dimensions of a common object, multiply each dimension by a scale factor, and examine a model using the multiplied dimensions. Students will then compare the surface area and volume of the original object and the enlarged model.

This lesson uses a real-world situation to help develop students' spatial visualization skills and geometric understanding. Emma, a new employee at a box factory, is supposed to make cube‑shaped jewelry boxes. Students help Emma determine how many different nets are possible and then analyze the resulting cubes.

Students experiment with units of liquid measure used in the customary system of measurement. They practice making volume conversions in the customary system.
6-8
Students learn the basics of the metric system. They identify which units of measurement are used to measure specific objects, and they learn to convert between units within the same system.
6-8
This lesson introduces relationships between measurement and geometry. The activities build on students' prior knowledge as students work with partners and as a whole class to identify and classify terms to develop their understanding of measurement.

In this year-long project, students design, "build," and "sell" a
house; after which they simulate investment of the profits in the stock
market. Along the way, students make scale drawings, compute with
fractions and decimals in various contexts, and even solve simple
equations. This lesson plan was adapted from an article by David B.
Smith, which appeared in the September 2000 edition of
Mathematics Teaching in the Middle School.

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.

This Internet Mathematics Excursion is based on E-example 6.3.2
from the NCTM Principles and Standards for School Mathematics. This is
the last activity in a sequence of four lessons designed for students
to understand scale factor and surface area of various rectangular
prisms. Students manipulate the scale factor that links two
three-dimensional rectangular prisms to learn about edge lengths and
surface area relationships.
