Are you looking to have some fun with numbers or a quick class-starter? This site may be for you! Enter a number and find out all you wanted to know but were afraid to ask. For example, enter 9 and you will find out that 9 is the only number (except one) which is equal to the sum of the digits of its square and that 9 is the smallest odd composite number. Below the list of information are common properties of the number entered. Some numbers also include links to web pages about that number - for example, enter the number 6 and there is a link to Some Thoughts on Number 6 by John Baez.

tag(s): data (148), numbers (203), puzzles (208)

How are rainbows formed? Why do they only occur when the sun is behind the observer? If the sun is low on the horizon, at what angle in the sky should we expect to see a rainbow? This lab helps to answer these and other questions by examining a mathematical model of light passing through a water droplet. Follow each step of the lab - how light travels, reflection, refraction, exploration, and analysis - to solve the questions. Each segment offers some information about the topic and questions to explore or experiments. The focus of each of the activities is the Mathematical equations and principals involved in creating rainbows.

tag(s): angles (88), colors (79), light (46), problem solving (272)

In the Classroom

Introduce this site on your interactive whiteboard or projector when introducing this topic. Then assign different sections to students to explore then present to the rest of the class. Have students create multimedia presentations based on information learned through explorations in the site. Have students use one of the many TeachersFirst Edge tools reviewed here.

Connect art and math using this site. The Bridges Organization was created in 1998 as an organization dedicated to promoting how Mathematics and the Arts work together. Each year they hold an annual conference in cities from North America to Europe. Members include mathematicians, artists, sculptors, dancers, computer scientists, and many more. The website contains background information on the organization, links to past conferences, and current conference information. Perhaps of most interest to classroom teachers are the links to the galleries. Contained within these are hundreds of works of art that have been featured at the conferences (try the link to the 2010 Bridges Conference for example). Click on any of the links and find pictures of their work along with a short explanation of how math is used in the piece.

tag(s): art history (70), artists (74), geometric shapes (163), tessellations (6)

In the Classroom

What a wonderful way to connect to students' multiple intelligences! After viewing examples of the artwork with your students, team up with the Art teacher in your building to have students create their own pieces of art based on math examples. Tie in writing by assigning students to write about their artwork and the math used as the basis of their art piece. Display art work with the explanations for other students to enjoy. Or take pictures of the art work and challenge students to create voice narration for the photo using a tool such as Thinklink,reviewed here.

The DeciFractor converts fractions to decimals from numbers you input. Fractions are then converted to their decimal value. There are several fractions already available on the site to use as demonstration; however the option is there to enter any fraction you would like. The numerator and denominator are clearly labeled and each of these numbers can be increased or decreased to demonstrate how the decimal will change by changing each part of the fraction.

tag(s): decimals (133), fractions (239), number sense (96)

In the Classroom

Use on the interactive whiteboard or projector to demonstrate and practice fraction to decimal equivalences. Before clicking to converta fraction you enter, have student predict the result. Use your whiteboard (and this site) to create a learning station for students to "try their hand at." Have students investigate patterns made by changing fractional parts. Be sure to click on the Ideas button towards the bottom of the page to get more ideas about how to use DeciFractor with your students.

Currently there are almost 2000 activities, lessons, and videos and the site is constantly growing. There are several ways to use the site both as a registered user or without registration. Without registering for the site you can search and access lessons and information through the different search methods such as keywords, subjects, source institution, and more. Free registration allows the site to become much more personalized. After registering, you can make lists of resources for any different topic, share lists or searches with others, add comments, or add your own resources. Most activities on the site are free; however, there are some searches that deliver lessons that are paid - these are clearly indicated and not frequent enough to discourage use of this site. Searches can also filter out any paid activities and return only free items. Teachers may also want to subscribe to the site's blog and newsletter to receive updated information as it is added to the site.

In case you are wondering about the title, SMILE is the Science and Math Informal Learning Educators pathway of the National Science Digital Library (NSDL).

Enjoy NASA's images of planets and spacecraft used in space exploration. This site is a great reference site for concise information about planets, and spacecraft. An online glossary contains space terms, and the origins of names for planets, moons, or spacecraft that are from Greek mythology, Latin, or famous people. Spacecraft information includes the assembly, lift off, and mission information. Spacecraft information comes in an audio format too. A CD is offered for sale from the National Space Science Data Center.

tag(s): earth (228), planets (123), solar system (119), space (205)

In the Classroom

In science, this site easily lends itself to planetary studies. Science classes can compare mass, density, atmospheric components, and surface materials. Math classes can use information provided for many real life math applications comparing distances, revolutions, temperatures, distance from the sun, mass, and diameter. Practice place value and estimation in a universal way. An extra challenge for gifted students can easily lend itself to mean, median, and mode as well as graphing possibilities. Consider Earth day activities to focus on the uniqueness of our planet and the qualities of our planet to maintain life as we know it. Include as a reference on your web site, or as an informational piece to web quests in math or science. Challenge students to create multimedia presentation highlighting one of the planets or spacecrafts. Have students narrate an image using a site such as Thinglink, reviewed here. For quicker projects, create electronic "posters" or word graphics for adopted word using tools such as Piclits, (reviewed here,) or Typogenerator, (reviewed here).

Create graphs by entering an equation or selecting an equation from the drop-down and watch what happens!. Try entering raw data for analysis. MathTrax graphs the equations and provides descriptions of those graphs using both text and sound, which is great for those with limited vision, weaker readers, or who need auditory cues. The text descriptions can be read by Java-capable screen readers such as Jaws for Windows, or can be inputted into speech synthesizing software to create self-voicing applications. MathTrax provides color and line settings for drawing graphs to aid users with different vision-impairments.

tag(s): charts and graphs (195), equations (155), functions (70)

In the Classroom

Download the program and provide opportunities to play and understand the relationships between graphs and equations. Have students work on individual laptops after a class demonstration on your projector or interactive whiteboard. Provide this link on your class website for students to access both in and out of the classroom.
