A Collection of Useful Internet Resources [Introduction] [Annotated Explorations: Specific or Broad] [Collections of Sites] [Conclusion] 

---

Searching through the Internet for resources for your classroom can be very time consuming and frustrating. This page was designed to help teachers incorporate the Internet in their Junior or Intermediate mathematics classrooms.

For those who have experience searching through the Internet for mathematics activities please continue on below in the annotated explorations. Others are invited to sample some specific pages that could be implemented in your classroom tomorrow. Please click on the highlighted text to visit the site. Directly below are 5 resource examples that may be found on the Internet.

1. Game -- Play with the Towers of Hanoi! Click on the buttons with the angle brackets that indicate the direction and number of pegs of the move. Change the number of disks and your number of moves will be recorded each time.
2. Lesson Plan -- Scroll down and click on See the Lesson Plan under Lesson One (of six) regarding problem solving.
3. Math History -- Attaching a face or a story to a mathematical concept may draw some students in. Check out Pythagoras here.
4. Interactive Activity -- In the yellow window on the left, scroll down and click on X-Intercept and watch what happens to the equations below as you manipulate the line.
5. Problem & Solution -- Find the area of the shaded region. Go through the solution and enjoy the poetry!

• Algebra Story and Word Problems

Tease your brain with problems! There are many concept-based problems with a grade level suggested for each. Or, try an interactive approach where you are walked through a problem, only you make all the decisions like in Finding the area of a pool deck.
• Chopping Broccoli

A fun introduction to some simple fractals, how they are created and where they are found in nature. This site also has a link to The Spanky Fractal Database for some cool looking fractals.
• Colourful Mathematics

"Colourful Mathematics is a series of educational software presenting advanced mathematical concepts to K-12 students in a game-oriented approach. The five games offered utilize simple colouring and/or drawing techniques to illustrate some state of the art mathematical concepts from graph theory and computer science." The games must be downloaded before being used.
• Encyclopedia of Mathematics

Explanations and definitions await for hundreds of mathematical terms and concepts. Search using keywords or explore alphabetically by clicking the letter that your term starts with. A fantastic resource!
• Fractals Unit for J/I Students

Cynthia Lanius has put together an extensive look at fractals for elementary students with access to printed versions of all her on-line pages. She explains what fractals are and why we should be teaching them. Her Java version of the The Sierpinski Triangle is incredible. Check it out!
• Geometry & Measurement Lesson Plans from BYU

Lessons Plans for grades 6, 7, and 8 with tests and overviews. Here is a grade 6 geometry unit with individual lessons plans.
• History of Mathematics: A Timeline

J. Fillmore, of the University of California San Diego, has prepared a clickable, chronological list of important highlights in the history of mathematics. Bring some background to your classroom with some information on when and where the math originated! From the Origins of Zero to Pythagoras' Scholarly Society to Magic Squares, there is something bound to enlighten or brighten up your classroom!
• History of Mathematics Archive

Another excellent resource to stimulate the math classroom. Look into the chronological timelines and appreciate the organization of the various periods. They also have two biography indices, (alphabetical and chronological) to help you find who or what your looking for
• Louisiana Challenge: Activities for the K-12 Classroom

Two interesting math lessons here including one on basketball players and their statistics.
• Math Projects for Science Fairs

There are many ideas for students to investigate in categories such as Numbers and Geometry.
• Uniform Polyhedra

Wow! Check out 80 different polyhedra with your students. Watch an animation of each one choosing from a well designed Visual Index. Line, face and edge information is also available.

• Canada's SchoolNet -- Math Department

It's Amazing Mathematical Object Factory is really amazing! This teaching tool generates permutations, combinations, pentomino puzzles and much more! There are also many links and descriptions of other useful sites such as Statistics Canada.
• Cuisenaire Learning Place

New problems appear every month for the elementary student from all math strands. The Replacing Trees problem is a good example relating the communication of a problem and environmental studies.
• Interactive Mathematics Miscellany and Puzzles

A wealth of text, animation and resources can be found here but leave a lot of time for exploring for something at the elementary level. Most deal with higher level thinking. Check out Alexander Bogomolny's collections of puzzles and other people's sites. His Exchange might answer some of your questions.
• Math Archives

Browse or search for the topic of your choice. There are so many possible connections such as Art and Music in Math Education and Arithmetic and each have small icons telling the viewer the grade level and additional information.
• Math Central

Browse by curriculum strand in the elementary (K-5) and middle (6-9) levels in their resource rooms.
• Math Forum

This site is incredibly exhaustive! Get hooked in the Elementary School Student Centre or stay on top of the latest as a teacher in their Research Division. Students can find answers to their questions by searching response archives or they can Ask Dr. Math (elementary or middle) their own question. The site is fully searchable and has links to a plethora of resourceful Internet sites all compiled in Steve's Dump. Students can also solve challenges with MathMagic in 4-6 and 7-9 divisions.
• Math Probe

Enjoy manipulating a line on graph paper to discover the characteristics of slope. What happens when the line is horizontal or vertical? As students move the line, the slope, the intercepts and the equation of the line constantly change. Or, watch the screen appear three-dimensional when manipulating its dodecahedron, as a net or a skeleton. Students can interactively explore a dozen other problems including bar graphs, probability, and conversion.
• Mathematics Lesson Database

Search by division (K-12) and/or content area (although I received too many errors when searching) or browse their entire database in chart form displaying content area, level, lesson title and author. Note that this site from the University of Illinois at Urbana-Champaign points you to other URLs where the lessons actually exist.
• Mathmania

Presently under construction, this site challenges its viewers with problems to solve.
• National Council of Teachers of Mathematics

View journal articles from Mathematics Teacher and Teaching Children Mathematics by using their own searching tool. Also useful is the Curriculum and Evaluation Standards for School Mathematics.
