MathLanding






Mathlanding is a resource and tools for elementary math specialists and teachers.   When you arrive on the home page it asks you a question:  "Can we help you find something?"   If you aren't sure, you can select a math topic and even narrow your search by grade.   

We searched fractions, geometry, math history, and probabilities just to see what kind of things it would bring up.   

I could see this being used as supplemental practice, review practice or even summer bridge activities.  

 No matter how you decide to use it, MathLanding is a great resource for your elementary math lessons.

KenKen Puzzles


KenKen puzzles are quite the puzzle to some: They can’t believe that KENKEN—something so delightfully addictive, so completely fun—has an educational basis.    It’s not a crossword. It’s not some extreme version of tic-tac-toe. So what is KENKEN and where did it come from? Simply put, it’s a grid-based numerical puzzle that uses the basic math operations—addition, subtraction, multiplication, and division—while also challenging your logic and problem-solving skills. By altering the size of a KENKEN grid, from 3 x 3 up to 9 x 9, and employing different combinations of the math operations, five different difficulty levels can be generated, and a seemingly endless number of puzzles. (And many players seem determined to try them all!) In a way, KENKEN is like a game of pool or even chess: The more you think ahead to your next move and consider all the possible outcomes, the better you’ll get—and the smarter you’ll become! 

KenKen recently announced their Classroom program which supplies teachers with KenKen puzzles on a regular basis. FREE! Sign up here.   Please be aware this is a limited time offer, subject to change or expire without notice!  Teacher Sign Up Here!

National Library of Virtual Manipulatives

The National Libary of Virtual Manipulatives was created to supply teachers with interactive mathematics manipulatives. It is available free of charge on the web.

 

 Learning and understanding mathematics, at every level, requires student engagement. Mathematics is not, as has been said, a spectator sport. Too much of current instruction fails to actively involve students. One way to address the problem is through the use of manipulatives, physical objects that help students visualize relationships and applications. We can now use computers to create virtual learning environments to address the same goals.

Web2.0 calculator

While it won't replace the TI-84 Plus, it can do what your average high school student needs it to do. The best part is, you don't have to use it on the Web2.0calc site because they offer three widgets that you can use to embed the calculator into your own blog or website.
