Challenge basic counting skills and problem solving using classic sliding puzzles. Not only will you find numerical sliding puzzles, but also colorful shape puzzles. Java applets make an interactive version of each puzzle appear below the "goal" you are trying to reach. There is also a targeted number of moves to reach the goal. There are many different types of puzzles, some more familiar than others. Be sure to be patient as puzzles load. Sometimes the interactive (drag to slide) portion does not appear right away.
In the Classroom
Share these puzzles on your interactive whiteboard (or projector) as a mind-bending challenge. Help students develop problem-solving skills such as thinking several steps ahead by offering the link on your class web page. Higher level and gifted math students can try to determine a formula for calculating the number of moves it may take to solve a puzzle. Give awards to students who accomplish the "goal" in the stated number of moves, then ask them to explain their strategy or think aloud as they repeat it on an interactive whiteboard. Offer a puzzle club for your mathematical/logical thinkers or simply develop visual thinking skills by sharing these challenges.You must be registered and logged in to add items to your favorites.

Choose from a selection of controls to create a demonstration of virtual protractors. Choose from one of ten activities to generate angles and use an actual protractor to measure and check the answer. Choose from "Show the angle," "Make and measure," "Make the Angle game," and others. All of the choices make this site easy to differentiate for a variety of ability levels. Even in lower grades, this tool will allow your students to visualize right angles and other angle basics.
tag(s): estimation (46), measurement (158)
In the Classroom
Use this excellent resource with an interactive whiteboard, projector, or using computer stations. Show students how to measure with a protractor as a class, in groups, or individually. Students can easily operate the demo themselves on your whiteboard. Follow up with additional activities that challenge students to use and measure with protractors. This may be a good site to list on your class website for students to access both in and out of the classroom.

This site offers a ton of links to math videos with supplementary support problems. There are many topics, and most include subtopics: everything from rounding to exponents to decimals to pre-algebra! It is a very cool place to find homework help or an alternative teaching approach for various math concepts from things as simple as adding whole numbers to more advanced topics such as geometry. The site is divided by click-able math topics. The site does have some advertisements, but they are fairly easy to overlook. If your district blocks YouTube, the videos may not be viewable. You could always view them at home and bring them to class "on a stick" to share. Use a tool such as Freemake Video Converter, reviewed here, to download the videos from YouTube.
tag(s): decimals (131), estimation (46), homework (46), money (185), ratios (56), statistics (124)
In the Classroom
Teachers could add this site to their class web pages to provide extra support. Specific videos can be shown on the interactive white board as part of learning centers to allow the math classroom to become more like a math laboratory. If you can't find the specific topic you are looking for here, why not challenge cooperative learning groups to create a simple video teaching the new concept(s). Use a site such as TeacherTube reviewed here, to share the videos.

"When will we ever use this math stuff?" Answer this question using Math Apprentice. Choose a character and then begin the journey. Walk (or skateboard) to different work sites, buildings, or businesses. Learn how math is used every day in these work places: architecture, bike and toy makers, cafes, and more! Listen to a brief introduction of the concept. Solve problems or free play to identify math concepts in real life. No account or login is required.
tag(s): business (57), careers (136), equations (153), measurement (158), ratios (56), STEM (153)
In the Classroom
This site is a terrific example of STEM integrated learning. This is a great site to share on your interactive whiteboard or projector. Have cooperative learning groups explore different careers or buildings and share how math is used at their locations. Why not have groups create a video using a tool such as Teachers.TV (reviewed here) or a podcast using PodOmatic (reviewed here), to share their mathematical discoveries! At the end of an introduction of a concept, use this site for specific math practice using a real life concept. For example, visit the bike shop to use math to determine pedal gear to wheel gear ratios and resultant bike speeds. Use as an individual activity, a team activity, or with the entire class using an interactive whiteboard. Follow up with a personal problem to solve. In this example, students can measure the two gears on their bikes (or their teachers bike brought into the classroom) to use the information for further understanding.

This math website is a resource for basic information on math concepts. Although it is rather "plain vanilla" in design, it provides some valuable information. Concepts include: Basic Math Skills, Pre-calculus, Calculus, Beyond Calculus, and Other Stuff. Dan also provides links to neat math extras like paradoxes and riddles.
tag(s): decimals (131), exponents (42), fractions (234), numbers (199), operations (123), order of operations (39), percent (83), prime numbers (33), square roots (23)
In the Classroom
The basic information on the concepts of math could easily be used in online teaching as an option to a formal textbook. The reading is easy to understand, and to-the-point. The problem of the week section of the site could be used as a challenge activity for students once a week in different math classes. Provide this link on your class website for help to struggling students or for your math lovers to explore on their own.Add your comments below (available only to members) | Become a Member

Looking for extra practice and better ways to track student progress? Use this free site for explanations of concepts, see example problems, and answer a practice problem. The English is British style, so remember that "revise" on this site means the same as "review" to Americans. Teachers can register their students to follow their progress. Registration is free, but does require an email address. If you plan to have students register individually, you may want to create your own Gmail account with up to 20 subaccounts for each group of students (by code name or number) within your classes. Here is a blog post that tells how to set up GMail subaccounts to use for any online membership service.

Download free shareware games to encourage thinking and practice identifying geometric shapes. Many of the downloads are games, while others provide opportunities to view computer art and find the hidden geometry or for students to create their own! There are also activities connecting math to physics and astronomy.
Be sure to check with your technology department about the ability to download these applications to school computers. Many districts have restrictions on the ability to download. Click on each game icon to read a description of the games included and some uses. Games are Mac and Windows compatible. Read their FAQ link with each set of games for the most asked questions about the shareware. Once downloaded, to "stop" a program, click Esc. If you are not allowed to install software on your own, share these powerful games with your math or art supervisors so they can advocate for you with the tech folks.

So the name may NOT be the most appealing.... But this site Crappy Graphs offers some amazing tools (and of course some giggling from the students - from the name). The site claims they chose the name of the site, "Because 'Awesome Graphs!"'sounded way too pretentious." Whatever the name may be, this site is a MUST SEE if you are teaching your students about graphs or Venn diagrams, or even if you need to create your own.
The first thing you need to do is choose your type of graph to create: Line Graph, Venn Diagram 2, or Venn Diagram 3. Then, visit the Tool Box. There you will find tools to enhance your graph: a brush, a tool to make thin white lines, a link to enable you to type text onto your graph, a tool to "grab and select stuff," and a color picker. This site is very simple to use.
The site also includes a glossary, to help you understand WHAT all of the tools are for (it is directly below the graph on the main page). There is an option to SAVE your graph, by clicking submit. If you don't click submit, you will lose your graph. If you want to save the graph, you must include an email address. The site will send you an email with a direct URL to your graph. It also displays on the screen once you upload your data. Here is a sample the TF review team made. Rather than using personal email accounts consider creating a teacher Gmail account and set up subaccounts for up to 20 students to register (by code name or number). If you plan to have students register individually, you may want to create your own Gmail account with up to 20 subaccounts for each group of students (by code name or number) within your classes. Here is a blog post that tells how to set up GMail subaccounts to use for any online membership service. Be certain to check your school's Acceptable Use Policy before using this site. This site also requires Flash. You can get it from the TeachersFirst Toolbox page.

In the Classroom
This is one cool tool that would be useful with elementary, middle, and high school levels. In the younger grades YOU could create the graphs together on the interactive whiteboard or projector. In the middle and upper grades, have students use the tool to create their own graphs demonstrating their understanding of a math problem. The Venn Diagrams could also be used in a science class (comparing elements), or literature (character analysis), or many other subject areas outside the realm of math.
This resource requires Adobe Flash.

This site offers an interesting look at the history of geometry. Learn about geometry during the times of the Egyptians, Babylonians, and Greeks, The Fifth Postulate Controversy, The search for Pi, coordinate geometry, non-Euclidian geometry, differential geometry, and fractal geometry. There is also an Assignment link at the bottom of the site. The assignment challenges students to research a famous mathematician. The research links are provided, and some are very lengthy.
tag(s): coordinates (31), pi (26)
In the Classroom
Use this site to help your students understand how geometry has evolved throughout the centuries. Have students work in cooperative learning groups (or independently) to research a mathematician. Challenge students to create a blog entry written from the perspective of the mathematician explaining what they have "discovered."Add your comments below (available only to members) | Become a Member

This site features 13 geometry questions, a printable "dot paper," and a link to a virtual Geoboard. Some of the topics (of the questions) include square roots (of 2 - 40), lengths of irrational numbers, and diagonal irrationals. The virtual Geoboard opens in a new window, so you can easily navigate between the questions and the Geoboard.

You have several options to use this site with your geometry students. You could print out the "dot paper" and display the question on an interactive whiteboard or projector, while students work independently at their seats and selected students share on the whiteboard (resist the urge to be Vanna White yourself). You could also share this site using the interactive Geoboards. If individual computers are available, you could have students try the 13 questions using their own interactive Geoboards. Have cooperative learning groups create 2-3 additional questions (related to the topic) for the class to try. Share them on your class web site for students to challenge one another.Add your comments below (available only to members) | Become a Member
