AAA Math: All
About Fractions |
Dozens of colorfully illustrated pages with explanatory lessons and
interactive practice games make All About Fractions my pick of the
day. Using the Table of Contents, you can jump directly to one of
ten chapters (such as Multiplying Fractions, Reducing Fractions and
Comparing fractions) or start at the beginning (Basic Fractions) and
use the Next Lesson link to continue through the site. My favorite
clicks are the timed exercises you'll find at the bottom of each
lesson page. |
|
Algebra Basics |
Algebasics is an online mathematics instructional resource that
takes a middle school, high school or adult learner through the
basics of algebra. The material is divided into sixteen sections,
which begin with, "the basics," and includes a section on applying
algebra to real-world situations. You'll need audio to get the full
value of this site! |

Arcytech:
Learning About Time |
Learning About Time starts with a history of clocks, then describes
the parts of the clock, and concludes with a lesson on telling time.
The practice section of the lesson is an interactive clock that I
only recommend for advanced practice because it does not have any
numbers on its face. Begin by choosing whether you want to see the
time on an analog or digital clock. After practicing one way, be
sure to try the other. On the analog clock, I really liked the
realistic way both hands move together as you mouse around the clock
face. |

Convert-me.com provides interactive metric conversion calculators
for over a thousand units and measurements. For example, to convert
five ounces to metric, begin by navigating to the weight page. Then
scroll down until you see the unit you know (ounces) and enter "5"
into the calculator field. On the Metric Conversions home page,
you'll find a handy chart of twenty-one metric prefixes, and a brief
history of the metric system. |

Fibonacci
|
Cynthia Conner created her Fibonacci website as a project for a
class in teaching elementary math. To navigate, click on the red
squares, as the section titles are not hyperlinked. She starts with
a biography and then introduces Fibonacci Numbers, the Golden Ratio,
Phi and the Golden Rectangle. Her last sections include examples of
the Fibonacci sequence in art, music and nature.

Fibonacci
Numbers and the Golden Section |
The Fibonacci pick of the week belongs to Dr. Ron Knott, and is
hosted by Surrey University. It is very extensive, and certainly has
something for everybody. Those wanting an introduction will first
find a definition of the Fibonacci sequence by clicking the
underlined link "add the last two to get the next" or scrolling down
to the "Fibonacci Numbers and Golden Sections in Nature" section.
Must see clicks include the Easier and Harder Fibonacci Puzzles
Pages, and the Mathematical Magic page, which looks at patterns in
the Fibonacci numbers. |
|
Graphing |
"For those of us who find working with Excel or other spreadsheet
programs a challenge, or for those who want their students to create
graphs quickly and easily with their data, Create-A-Graph is the
answer. Users choose the type of graph they want (area, bar, line,
pie), plug in your data, and a graph is instantly created! What's
even better about this website is that the graph is created as a
picture file (choose .jpg or .png file type) that can be copied and
pasted into other documents or presentations, printed, or saved." |
|
Lattice
Multiplication |
This site includes a video demonstrating a method of multiplying
large numbers using a grid. This type of lattice multiplication was
introduced to Europe in 1202 in Fibonacci's Liber Abaci, according
to the website. This method breaks the multiplication process into
smaller steps, which some students find easier. Digits to be carried
are written within the grid, making them harder to miss. |
|
Magic Squares
|
Magic squares received their name because there are so many
relationships between the sums of the numbers filling the squares.
Fits well with the current suduko craze. |
|
Math eBoard |

Math Forum: Ask
Dr. Math: Golden Ratio, Fibonacci Sequence |
"Please tell me about the Golden Ratio (or Golden Mean), the Golden
Rectangle, and the relation between the Fibonacci Sequence and the
Golden Ratio." Dr. Math answers these three frequently asked

from the Dr. Math Archive. Wondering how to calculate the Fibonacci
numbers? The first three answers in the archive list describe three
different methods. |

The
Math Page: Topics in Precalculus |
"When one thing depends on another, as, for example, the area of a
circle depends on the radius, or the temperature on the mountain
depends on the height, then we say that the first is a ‘function' of
the other." Lawrence Spector, a math teacher at Borough of Manhattan
Community College, introduces precalculus with twenty-five topics
including logarithms, polynomials of the second degree, irrational
numbers and mathematical induction. If you return to the homepage,
you'll find another twenty-one trigonometry topics, along with
lessons for algebra, plane geometry and calculus. |
|
The Math Website
|
Probably one of the best math teacher websites. They call it the
"Math Teacher Robot." You will probably want to click on the list
of topics at the bottom but that just gives you a rollover
description of each area. Be sure to click the blue ENTER button at
the top right to access the resources. |

Virtual
manipulatives |
Created by a team of researchers and educators at Utah State Univ
with support from the Nat'l Science Foundation, this new online
library of interactive manipulatives is intended to help educators
accomplish the task of engaging students in daily math lessons.
Whether you're teaching basic math concepts, from simple algebra or
geometry to units of measurement, or more advanced lessons on topics
such as data and probability, chances are you've found yourself in a
situation where, no matter what you do, your students seem either
unable, or unwilling, to grasp the concept. Because learning and
understanding mathematics at every level requires student
engagement, the researchers behind this three-year project have set
out to create a vast library of manipulatives/tutorials, intended to
help students visualize and apply these often difficult mathematical
concepts. |
