This site offers many opportunities for math exploration for both teachers and students. Although they have a store and ads on the site, much of the site is free and worth a visit. One especially helpful portion of the site is the link to different types of calculators from basic to graphing to mortgage and loan calculators. Students and parents will find the homework section of the site helpful as it is categorized by different topics, then each topic is further divided into sections. For example, under fractions you will find definitions, reducing, adding and subtracting, multiplying and dividing. In each of those portions there is a section with a first glance (overview), in-depth, examples, and workout. There is also a unit quiz for each section. Another helpful area of the site is the practice section which offers practice in many different math skills such as square root, percent, and integers. The games section offers practice with critical thinking skills through logic puzzles and games such as chess.
This site includes advertising.

tag(s): calculators (40), fractions (229), integers (40), percent (80), test prep (94)

Looking for different types of calculators? Find them on this interesting site. Choose a button on the calculator corresponding to the subject. Examples of subjects include Medicine, Algebra, Weather, Phonics, Financial, HVAC, Engineering, Weather, and Rocketry to name a few. After the subject is chosen, click on a formula to enter values. Some of the topics offer reference information, not calculations. This is definitely an interesting site to peruse.

tag(s): energy (208), medicine (66), phonics (68), rockets (18), sports (97), weather (206)

In the Classroom

There are many different calculators for students to explore as ways to apply math in real world situations. For example, choose weather and then wind chill. Enter the information and wind chill will be calculated. Enter the information, view the calculated answer, and then have students determine how it is actually calculated. This site is a great find for gifted students to use to further investigate specific topics beyond your "regular" classroom content. Share this site on your interactive whiteboard or projector. Then have students work with a partner to explore various "buttons" on this interactive calculator. Have the groups create multimedia presentations to share their findings or demonstrate them on the whiteboard as advertisements or infomercials! Have students create online posters on paper or do it together as a class using a tool such as Web Poster Wizard (reviewed here) or PicLits (reviewed here).

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 (155), numbers (191), puzzles (205)

In the Classroom

Display the page on your interactive whiteboard or projector at the beginning of the class to spur math discussion.

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 (87), colors (77), light (54), problem solving (292)

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.

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.

In the Classroom

Use this site as a resource to supplement current classroom activities. If you are just implementing math journals, this site is a wonderful resource for ideas and implementation. Print out game directions for use at centers or in folders. Share this site on your class webpage for students to access both in and out of the class for extra practice and/or enrichment.

Comments

This site has proved an invaluable resource for teachers at my school. Lots of great resources for Math Centers/small group work and the journal tasks for K-5 are all really good! Highly recommend it to any teachers and/or math coaches trying to get their head around the Common Core Standards. Jane, , Grades: 0 - 5

This activity provides the opportunity to explore experimental probabilities through simulation of a coin toss. In this activity you can view the results as a list, ratios and probabilities, and a table. In addition, the choice is available to view cumulative stats or not. The learners section of the site contains an explanation about probability and how it is used in science and medicine. The instructor portion has information on how the activity can be used in the classroom, links to standards, and similar resources.

In the Classroom

Use this site as an anticipatory set or "activator" to introduce a unit or lesson on the difference between chance and probability. Share the site on a projector or interactive whiteboard. Complete the activity showing results as a table. Then have students convert those results to a table and ratios. Allow students to explore the site and compare results - discuss comparisons between individual results and results found when combining all results.
