Calculus On the Web: http://www.math.temple.edu/%7Ecow/
COW is an internet utility for learning and practicing calculus. It was designed at Temple by two members of the Temple University Mathematics Department, Gerardo Mendoza and Dan Reich. The principal purpose of COW is to provide the user with the opportunity to learn and practice problems in calculus (and in the future other topics in mathematics) in a friendly environment via the internet. The most important feature of the COW is that you get to know whether your answer is correct almost immediately. It is as if you had a tutor looking over your shoulder and helping you along as you work. This will be true no matter where you are or what computer you use, as long as it is connected to the internet and has a web browser.

Math2.org: http://www.math2.org/
Students who need a quick math reference, rather than a detailed explanation, will find all sorts of help here.

This makes it easy to brush up on the formula for determining the circumference of a circle, convert fractions to decimals and prove calculus theorems. A message board, suggested books and software, and links are also available.

Integer Cards
1)Pick your teams and chose one person to be dealer. (ex. 5 teams of 4 but teams do not have to be even.
2) Make target cards for each group. The target cards have a number from -20 to +20 on them. One number per card.
3)Red cards are negative and black cards are positive. Aces=1, Jacks = 10, queens = 11, and kings = 12. All other cards are the value shown (2=2 etc)
4) Each player gets 2 cards from the dealer. The dealer also takes the top card off the target card for the card the players are aiming for.
5) Players take turns trying to make their 2 cards equal the target card. They may add or subtract to reach it. They must use both cards to reach the target #. (This eliminates the player who has a red 7
and the target is -7) The first player to reach the target # wins a point. The dealer must figure each "correct answer" out to ensure it is correct. Cards are shuffled and play continues.

Take black and white headshots of each student, sized it to a quarter page with a box frame around it ... then added a blank box beside it (the same size as the framed picture). This would take up the top half of the page. Repeat the process with another student's headshot and empty box below that first one. Then cut the page in half giving each student their own headshot and blank box on the half-sheet. The students then draw 1/2 - 1in. gridlines in pencil on both the headshot and the empty box next to the headshot. They label the gridlines as 1, 2, 3, 4, 5, etc., going each direction. They try to duplicate their pictures by drawing only what they see in each box.

Tessellation sites
Mathematicians define "tessellate" as covering a plane with a pattern, and it is a concept that interests scientists and artists, as well as mathematicians.
Intriguing Tessellations: http://members.aol.com/tessellations/
Curiosity spurred nature artist Marjorie Rice (with no formal training beyond high school mathematics) to discover four new tessellating pentagons in the late 1970's. Including those Rice discovered, only fourteen tessellating pentagons have been uncovered, and the question of whether or not there are more remains unsolved. To learn about Rice's discovery, follow the link to "Perplexing Pentagons." Links to Rice's amazing tessellating art (based on the patterns she created) are found below each pentagon design.
Tessellating Animation: http://www18.big.or.jp/~mnaka/home.index.html
Japanese artist Makoto Nakamura has taken tessellations a step beyond the plane with his awesome animations. See his tessellated birds fly, his tessellated fish swim, and his tessellated dancers dance. Visit Nakamura's Jigsaw Puzzles. Here you will have a chance to reassemble tessellated cats, pigeons, gorillas and more. Each interactive puzzle is unique and intriguing in its own way.
Tessellation Tool: http://www.boxermath.com/plp/modules/online/workshop/toolbox/mosaictool.html
If all this tessellated art has you eager to create your own patterns, take a look at this cool tool. Start by dragging a shape onto the white board. Next, you rotate or color your shape, and repeat as needed. All of the polygons have sides of equal length, so they fit together perfectly. Two more sites with interactive design tools are Pattern Blocks: http://www.arcytech.org/java/patterns/patterns_j.shtml and Virtual Manipulatives: http://matti.usu.edu/nlvm/enu/navd/frames_asid_169_g_1_t_2.html.

This Math Forum page is an introduction to tessellations for those who know some geometry. It defines regular tessellations (those made up of polygons whose sides are of equal length), and shows how the interior angles of a regular tessellation must be an exact divisor of 360 degrees. Included are links to a lesson plan (for teachers and homeschoolers) and additional activity pages for students. You can experiment with shapes from this (or any other site) by copying them (use a right mouse click) to a paint program. Within the paint program, you can rotate and paste the shapes into tessellations of your own.

Teaching percentage to middle school students:
Have students bring their favorite magazines from home, and provide a few as well. Start the lesson by talking about fractions....1/2 of a page, ¼ of a page, etc. Working with a partner, students start at the beginning of their magazine and record on a tally chart the number of ads in the magazine. They then calculate the percentage of ads in their magazine (89.5 pages of ads out of 120 pages). It's a real eye opener for the students to learn that most of their magazines have more than 50% advertising. Record the percentages on a big chart paper and the students select ten magazines to highlight in a bar graph........they must show the amount of advertising in the various magazines in ascending or descending order.......using a computer program such as Excel or Quattro Pro.
