Maths Is Good For You offers a history of mathematics and loads of math activities for young mathematicians. Although the site isn't very visually pleasing, it contains quite a bit of mathematics background and information. Learn about famous mathematicians, famous places in math, and the background on some of the origins of mathematics. Be sure to check out the worksheets section for some interesting and quirky activities. This site was created in the UK. American English speakers may notice slight spelling differences. There is also mention of Key Stage 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).

tag(s): egypt (45), numbers (120), pythagorean theorem (20), roman numerals (7), worksheets (68)

#### In the Classroom

Use Maths Is Good For You as a starting point for information on famous mathematicians and theories. Have students upload a photo they have taken and add voice bubbles to explain what they learned using a tool such as Phrase.it, reviewed here. Have students use Fakebook, reviewed here, to create a "fake" page similar in style to Facebook about a famous mathematician. Print and use worksheets for homework, math centers, or to differentiate instruction. Have students create interactive timelines using Sutori, reviewed here, with images, text, and collaboration and using timeline information found on this site.

Are you interested in numbers? This site has a variety of videos about math theories that are at the forefront of research. Easy, understandable language presents each topic, and this is an entertaining way for anyone to learn fascinating facts about numbers. The Numberphile covers a very broad scope of topics such as Why do people hate mathematics, AMAZING Dice Rolls, and Sounds of PI. Videos vary in length, although most remain well under 15 minutes. Even those who believe they are not good at math will like learning interesting facts about numbers. The videos are hosted on YouTube. If your district blocks YouTube, then they may not be viewable; be sure to look at alternatives for sharing the conversation starters and other videos on classroom computers. Use the search bar to find specific topics faster

tag(s): calculators (38), negative numbers (12), number lines (33), numbers (120), pi (25), prime numbers (25), video (246)

#### In the Classroom

Share these videos on your interactive whiteboard or projector as wonderful math journal and discussion starters. Choose a video about an interesting number fact that can be used to hook students into a particular lesson or unit. Use the videos to show the fascinating side of mathematics. For example, 666 and its peculiarity in mathematics would be interesting to students. Make a math enrichment center for your gifted students or "hook" math-haters (or girls) by letting them select and critique their own video choice from this site. Embed a video on your class wiki and have students use the discussion tab to comment on what they like about it or were surprised to learn. Use in your blended classroom by flipping and having students view the videos at home to discuss the next day in class. (This is a great option if YouTube is blocked in your school.) Be sure to provide this link on your class website for students (and their families) to access at home. Modify learning by having students make their own advertising videos about their favorite or "lucky" number using a tool such as MoocNote, reviewed here, where students can embed questions, comments, and polls into videos. Then share them on a site such as TeacherTube, reviewed here.
