This fabulous UK site offers many resources for math practice and instruction. Choose the Videos and Worksheets section to find a large list of topics sorted alphabetically including instructional videos and practice questions. Many also include corresponding textbook exercises. Choose 5-a-day to find another large selection of printables for daily review, choose from three different levels for each date. (U.S. users will need to "translate" the 5-a-day letter equivalents to find approximate grade levels; count backwards from grade 12 being "A.") Conundrums for each day of the year provide short, daily brainteasers ready to print and use. Don't miss the Great Maths Bakeoff, a terrific idea for Pi Day! This site was created in the UK. American English speakers will notice slight spelling differences and use of English currency. There is also mention of Key Stages 3, 4, and 5. In America, these stages equate to Ages 11-14 (Stage 3), Ages 14-16 (Stage 4), and Ages 16-18 (Stage 5). Some of the videos are hosted on YouTube. If your district blocks YouTube, the videos may not be viewable.

In the Classroom

Use printables and worksheets from Corbettmath for homework, review, and reinforcement of any math concept. View videos together and have students complete practice questions. Create a link to YouTube videos on your class website or blog for students to view at home. Use this site to differentiate for students of all levels. Share this site as a way to review before tests.

Use this site as an anticipatory set or "activator" to introduce a unit or lesson on a projector or interactive whiteboard. Use to find a question of the day to begin lessons. Share or embed questions on your class website. Have students prepare a question of the day to include with your quizzes. See the "About" page to find questions for class discussions. Though they suggest using mini whiteboards or a large card, think about using computers or tablets and a student response system, such as Socrative, reviewed here. Using a student response system, you will be able to keep a record of the responses without having stacks of paper. It will help you to differentiate and know whom to focus on with some immediate extra help.

Choose one of the examples (such as Bisect an Angle) then click the "Play All" button to follow the step-by-step procedure in action. Stop the animation at any point and resume play when ready. In addition to using examples provided, create your own constructions using commands found in the "How to" link. Robocompass interfaces with Google memberships, allowing you to SAVE animations! For a good overview of the site, choose "Take the Tour." (The tour button only shows AFTER you have clicked a sample file or "Open Robocompass.") This option offers a video overview and explanation. If your district blocks YouTube, "Take the Tour" may not be viewable. The tool states it operates best in Chrome and requires WebGL. You need to enable Web GL to use it in Safari. See directions how in this blog post. iOS and Android apps are "coming soon." Imagine this one on a tablet! Note: This site uses significant bandwidth to load the animations and the tour video. Be patient.

Be sure to provide this link on your class website for students (and their families) to access at home for additional math practice or help. Sometimes seeing a slightly different explanation helps understanding.

Then enter the problem. Problems automatically format as you enter them. Click Solve to view the step by step process to obtain the answer along with rules used, if applicable. Click on the rule to view an explanation and example. Scroll through links to all reference material. Never before has "solve for X" been so instantaneous! You can even copy a direct link to the solution to share it with others.

In the Classroom

This site is perfect for use on your interactive whiteboard or projector. Use with practice problems or when comparing different processes for obtaining solutions. Create a link on classroom computers for students to use when checking work. Share a link on your class website for students to use at home. Have students provide their attempts at problem solving. Print the solution using cym@th. Have students share where they were stuck or having problems in finding a correct answer. How do you prevent this from becoming an instant homework "cheat"? Always start with actual word problems, not equations, so students must first generate their own equations. Require students to "show their work" on paper as they solve, including the explanation of each step. Even if they are copying from the web site, they are still copying down the explanations. If they use their own words, that will show comprehension. How else could you prevent using this tool as a "cheat"? Feel free to add a comment!

This tool is great for creating and visualizing math concepts from basic geometric shapes and area to complex constructions and trig. Use on a whiteboard or with a class projector for interactive classroom use. Save or retrieve creations with Dropbox, reviewed here or Google Drive, reviewed here. Use for hands-on work with any geometry or trigonometry functions. Since this tool works on such a variety of devices, it would be ideal to use in a BYOD (or 1:1) geometry class. Art teachers who want to "draw in" their more mathematical students can offer this as a design option, especially when teaching about perspective.
