If you are looking for many different variations of math puzzles, look here. This site contains many puzzles of all kinds, together with links to other puzzles and mathematical recreation pages. The puzzles are marvelous, though many are a bit hard to understand -- often the author starts talking about a group of puzzles without explaining what the puzzle is. You may also have to work your way through some other random thoughts by the author; however, the puzzles on the page are worth sifting through the page to find them. Puzzles are listed in order of being added to the site, it may be easier to find items by looking on the right-hand side of the page and following the links listed under "Math Games". Activities are listed here by title without any explanation or picture, it would have been easier if they were in alphabetical order; however, this is still easier to find than scrolling through the long page of activities.

tag(s): logic (243), problem solving (277), puzzles (207), trivia (18)

In the Classroom

Introduce the site on your interactive whiteboard or projector then challenge students to choose a puzzle to solve. Have students explain the solution to the class. Use puzzles as a Problem of the Week for homework or extra credit by posting on your classroom website or blog.

"Aesthetic computing" is an approach to algebra that focuses on students representing algebraic equations as pictures and stories to increase student involvement and understanding. The goal is to engage students who would benefit through hands-on and visual approaches to learning. The site includes a 5 minute video describing the approach, an introduction to the theory including lesson plans and handouts, and learning outcomes. Lesson plans are divided into Middle School and High School categories. One interesting inclusion to the site is the online chat and group for teachers interested in trying the approach. The group is very small but might be worthwhile to use for networking with others using this approach.

tag(s): operations (126), problem solving (277), visualizations (13)

In the Classroom

Share this site with Special Education and Gifted teachers as the hands-on approach will appeal to both types of learners. Display and share students' pictures and stories in your classroom or on your classroom website. Challenge students to find the equation within the pictures and stories.

When searching by genre there is a link explaining the puzzle type included under that heading. Membership in the site is free and not necessary to solve puzzles; however, members can see puzzles they have already solved, statistics, and perhaps most interesting - can create their own puzzles to upload to the site. Membership does not require an email address.

This site offers many opportunities for math exploration for both teachers and students. Although they have a store and ads on the site, much of the site is free and worth a visit. One especially helpful portion of the site is the link to different types of calculators from basic to graphing to mortgage and loan calculators. Students and parents will find the homework section of the site helpful as it is categorized by different topics, then each topic is further divided into sections. For example, under fractions you will find definitions, reducing, adding and subtracting, multiplying and dividing. In each of those portions there is a section with a first glance (overview), in-depth, examples, and workout. There is also a unit quiz for each section. Another helpful area of the site is the practice section which offers practice in many different math skills such as square root, percent, and integers. The games section offers practice with critical thinking skills through logic puzzles and games such as chess.
This site includes advertising.

tag(s): calculators (41), fractions (234), integers (41), percent (83), test prep (96)

In the Classroom

Create a link to this site on your classroom website or blog to share with students and parents as a resource at home. Display portions of the site on your interactive whiteboard or projector when introducing a unit or lesson or when reviewing at the end of a unit. Use the calculators on your interactive whiteboard during whole class lessons.

Are you looking to have some fun with numbers or a quick class-starter? This site may be for you! Enter a number and find out all you wanted to know but were afraid to ask. For example, enter 9 and you will find out that 9 is the only number (except one) which is equal to the sum of the digits of its square and that 9 is the smallest odd composite number. Below the list of information are common properties of the number entered. Some numbers also include links to web pages about that number - for example, enter the number 6 and there is a link to Some Thoughts on Number 6 by John Baez.

tag(s): data (153), numbers (203), puzzles (207)

In the Classroom

Display the page on your interactive whiteboard or projector at the beginning of the class to spur math discussion. Choose some interesting information on numbers to use for a Fact of the Day or Interesting Information of the Week for students. Create a bulletin board displaying interesting facts about numbers for your classroom.

The goal of this site is to provide the finest quality paper-based teaching materials to teachers and parents around the world. Myriads of options are available to create worksheets in Math, English, Geography, Puzzles, and Miscellaneous. Just choose a subject, then a topic, and choose from options offered to create your own worksheet that can be printed in pdf form. This allows the worksheet to be shown clearly on interactive whiteboards eliminating the need to print each creation. Although it was created for teachers, a more useful purpose may be for students to create their own worksheets to share with other students or for self-practice.

tag(s): printables (38), puzzles (207), worksheets (62)

In the Classroom

Use this site to differentiate for students of all levels by allowing students to create their own worksheet for practice or review. Make a shortcut to this site on classroom computers and use it as a center - students can then create their own individualized practice.

This ativity provides positive reinforcement of correct math answers with a basketball player taking a shot at the basket. Click Start or any of the questions in the Table of Contents left of your window to see a mathematics question and animation. If you answer the question correctly, the result will be a basketball shot animation; incorrect responses yield the correct answer. Questions include various strands and levels of mathematics such as rounding numbers, perimeter, word problems, common factors, and much more. At the completion of each round, the score appears with the number of correct responses and percentage correct. You must either click the back button (if you want to remain within the same topic) or click on a new topic to move on to the next question. The game is available in Spanish.
