* * Mathematics **
A wealth of mathematics materials is available on the Internet accessible
from many educational databases. To appreciate the variety, look at these
excellent examples. As you do, critique the lessons in the following areas.
- creative activities
- use of the Web
- links to related sites
- teacher instructions
- assessment of student learning
The best lessons will have all of these attributes!
Functional Housing Market
Students will access the Internet to search for housing prices in Houston,
Texas, (the location can be changed to accommodate any location) and compare
the prices to the number of square feet found in the living area of a house.
A linear equation will be derived from this data on a coordinate plane
using the "best-fit" method. Using information from the graph
of the data and the equations of the function, students will answer questions
about housing prices.
Up Fractions Reinforce students' skills in multiplying and dividing
fractions by increasing and decreasing the serving size in a recipe. Students
will also practice using search engines. Searching for recipes on their
own to increase and decrease the recipe size. (Make sure fractions are
in the recipes they choose).
Internet Pizza Server
Students will create their own pizza using choices of toppings. They
will be able to "order" their creation from the Internet and
see a digitalized version of their pizza. They will use their order to
calculate the area of various size pizzas, determine the "better buy",
& cost per topping. Students will also have to use research skills
to answer questions pertaining to the Internet Pizza Server Home Page.
Fractions with Cuisenaire Rods
What are Cuisenaire Rods? Cuisenare Rods are a collection of rectangular
rods, each of a different color and size. The smallest rod is one centimeter
long and the longest rod is 10 centimeters long.
- No Matter What Shape
Your Fractions are In
These activities are designed to cause students to think; they are not
algorithmic. Students will explore geometric models of fractions and discover
relations among them. Appropriate Grades: 3rd - 6th, maybe. But precocious
kindergarteners could do some of it, and middle schoolers needing another
look at fractions could appreciate it as well. "Drawing Fun Fractions"
would be good for most middle school students.
- A Fractal Lesson
Students make a Sierpinski Triangle and a Koch Snowflake and explore
fractal resources on the Internet in this lesson for elementary and middle
A great site! The problem is meticulously posed, the graphics are excellent
and it is fun to "play". The is a full explaination of the solution
and nice generalization of the problem for n doors.
These pages were developed through GirlTECH '95, a teacher training
and student technology council program sponsored by the Center for Research
on Parallel Computation (CRPC), a National Science Foundation Science and
This lesson uses the Internet to research a company in the stock market.
Students find a description of a company and its products and a report
of its earnings during the past year. They track stock data and analyze
and graph it using Mathematica.
