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.

tag(s): logic (248), puzzles (203)

#### 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.

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 (48), measurement (175)

#### 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 (125), estimation (48), homework (42), money (185), ratios (63), statistics (127)

#### 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 (58), careers (139), equations (151), measurement (175), ratios (63), STEM (173)

#### 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 (125), exponents (43), fractions (228), numbers (197), operations (123), order of operations (40), percent (82), prime numbers (31), square roots (22)

#### 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.

Interested in learning how to use your interactive Smartboard (or any brand of whiteboard) to support good math instruction? View interactive activities by Kentucky Math standards, grade level, or content. Preview the resource or download (SMART Notebook format only) for use in the classroom. SMARTboard software is required for using downloaded files. Other activities feature activities using content from another site and a description for using the resource. Many of the outside sites are interactive (and fantastic).

The activities are divided up by grade level. There is something here for all grade levels. You can also search activities by name: clock templates, Pythagorean theorem, graphing coordinate pairs, spinners, and many others.

tag(s): charts and graphs (197), counting (113), fractions (228), iwb (32), numbers (197), patterns (87), volume (53)

#### In the Classroom

Unlock the power of the interactive whiteboard by using these activities to introduce or reinforce concepts in a variety of Math subjects. For example, teach geometry using the "Geometry in Action" activity which uses architecture to teach geometric concepts or use "Cubic Volume" to fill a rectangular prism with cubes to determine the volume. Be sure to check out the external sites also, there are some gems! If you have a different brand of whiteboard, preview the ideas for the downloadable files, then check your company's software for an equivalent activity. Many offer very similar resources.
This resource requires Adobe Flash and PDF reader software like Adobe Acrobat.

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.

Data on correct and incorrect answers as well as strengths and weaknesses are kept for students. This site does include some minor advertisements. Watch out for a link to "essay paper" buried at the far bottom right on the home page: a place to purchase essays online!

tag(s): coordinates (30), exponents (43), fractions (228), integers (40), percent (82)

#### In the Classroom

Use this site for extra practice or answering a problem after initial teaching. Identify strengths and weaknesses for grouping students in solving problems. Share this link on your class website for students to use for extra practice and as a resource outside of the classroom.

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.

tag(s): numbers (197)

#### In the Classroom

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.

AlgebraLAB highlights the connection between algebra (and many other math subjects) and science. Although this website may appear as an in-depth informational algebra site, there is A LOT more to explore! AlgebraLAB includes 10+ links to various topics: Lessons, Practice, Careers (how Algebra and science are used in countless careers), Directions (offers insight on how to use this site), Word Problems, Study Aids, a Glossary, and several others. Many activities are interactive. This site requires Windows Media Player. You can get it from the TeachersFirst Toolbox page.

#### In the Classroom

This informational site is a MUST HAVE in any secondary math class. Be certain to save this site in your favorites. The site highlights countless algebra topics (and other math areas). Share the information on your interactive whiteboard or projector. Share the link on your class website so students can access the site both in and out of the classroom. Have cooperative learning groups explore one of the topics presented at the lessons or activities link. Have the groups create a video to share what they learned. Share the videos on your interactive whiteboard or projector using a tool such as TeacherTube (explained here). Differentiate! You can easily find extension activities for your more-able students to do while you reinforce the basics with others.
