The Cyberchase kids' adventures at "Sensible Flats" introduce
students to the concept of area in an engaging and entertaining way. Cyberchase
is a daily, animated adventure television series and multimedia project
for children ages 811, about a team of kids on daring missions in Cyberspace.
Our heroes have to use math and brain power. In this episode, the Cyberchase
kids have to prove that regular and irregular shapes may have the same
area in order to save the day. Interactive Web sites will provide students
with practice in calculating both area and perimeter, and real world problems
will encourage students to discover that math is fun and something we
experience, not just in school, but all around us, everyday.
Students will be able to:
 Select and apply a variety of strategies to solve problems
 Calculate the area and perimeter of regular and irregular shapes
 Demonstrate an understanding of the relationship between area and
perimeter

Connections
 Students will recognize and use connections among mathematical ideas.
Geometry
 Students will analyze characteristics and properties of two and
threedimensional geometric shapes and develop mathematical arguments
about geometric relationships.
 Students will apply transformations and use symmetry to analyze
mathematical situations.
 Students will use visualization, spatial reasoning, and geometric
modeling to solve problems.
Measurement
 Students will understand measurable attributes of objects and the
units, systems, and processes of measurement.
 Students will apply appropriate techniques, tools, and formulas
to determine measurements.
Problem Solving
 Students will build new mathematical knowledge through problem solving.
 Students will apply and adapt a variety of appropriate strategies
to solve problems.
