Math10 contains math resources for primary and secondary math students and teachers. Choose from categories such as Problem Solver, Adding and Subtracting Up to 100, Math Tests, Math History, and more. The topics of math problems vary from primary grade topics up through post-secondary. Search the topics on the left toolbar. The Math History portion is an in-depth look at math throughout the ages including classical Greek geometry through the origins of calculus. Games are divided into categories beginning with addition games through coordinates and equations. Be sure to check out the problem of the week for a new activity weekly.

tag(s): pythagorean theorem (44), fractions (335), problem solving (407), square roots (30), multiplication (285), mixed numbers (15), equations (224), probability (179), exponents (58), sequences (20), division (215), polynomials (39), logic (326), operations (161),

#### In the Classroom

Share portions of the site as needed on your interactive whiteboard. Use the Problem Solver applications to demonstrate and share any problems you want to work out as a class. Have students use the Problem Solver and then write a journal entry describing the steps used in solving the problem. Assign different portions of the Math History section of the site to students to use when learning math history or as a backdrop to put concepts into context. Share this site on your website or blog as a resource for students to use at home. Use discussion topics from the site's forum in your classroom. An example would be to discuss the topic if math is the most boring or difficult subject and why.

Discover irreverent, creative new projects featured every week in Evil Mad Scientist blog. This blog features applied science and math concepts in unique or unusual ways. A few of them push the envelope, but all will get you thinking. Every Wednesday, new projects tickle your imagination. Watch videos, read the latest stories, or comment on existing projects. Browse the shop,-- not to buy, but to see and analyze remarkable inventions. Join a mailing list to never miss new projects. Note: a few of the ideas involve hacking electronics and computers, so the site may be blocked by school filters. Preview to know for sure. See notes below on ways to share specific articles.

tag(s): inventors and inventions (147), creativity (186), scientific method (84), STEM (353),

#### In the Classroom

Inspire creativity and original thinking with Evil Mad Scientist. Use as inspiration or examples for student projects in art, science, or music, research, or applied creativity. If you share a link with students, you may want to link to a specific post or use Readability Test Tool, reviewed here, to provide a "clean view" of the post. Evaluate projects together on the IWB to help students identify characteristics of creativity and talk about how the ideas may have come to be. Use this site during a unit on scientific method so students connect the discipline of research with the creative results. What kind of experimenting took place? What principles of science? Compare the inventions available in the Shop with inventions from the Industrial Revolution. How is today a different environment for inventors (or is it?) Begin your own Evil Mad Scientist blog to feature your students' creativity or slightly irreverent ideas in a safe and school-appropriate environment, almost as an STEM graffiti wall.
