The goal of this game is to move the provided shape to the chest along a trail in as few moves as possible. Once the chest is reached, rotate the shape correctly to open the chest to receive the prize inside. You choose the path to follow, and difficulty is increased as each level is reached. In addition to moving the shape along the path correctly, you will have to know the degree of the angle the shape will have to turn to go inside the chest. The activity begins with a narrative and demonstration showing how to play. Several geometric definitions are available by clicking the book link within the game.

tag(s): logic (248)

#### In the Classroom

Practice vocabulary of geometry terms by allowing students to play the game, as they reach each level, challenge them to define terms such as rotation, reflection and translation. Set up the activity at a computer center to practice logic and problem solving skills. Challenge students to create their own map with a path for other students to play.

The Common Core State Standards Initiative is a nationwide effort led by the National Governor's Association and the Council of Chief State School Officers to establish a common set of educational standards which aligns benchmarks and expectations across state lines. This system builds on what states are already doing by providing an opportunity to share experiences, best practices, and lessons, while maintaining high expectations that insure the quality of education across America to enable our students to maintain a competitive edge in the global economy.

Visit this website to find out exactly what the national K-12 standards are for English language arts and literacy in history/social studies, science and technology, as well as mathematics, and to find out if your state is one many states (at the time of this review) that have already committed to adopt the Common Core State Standards. Watch videos and the recorded webinar, and read about the key points and rigorous curriculum standards, including the content and skills related to the use of media and technology for critical analysis and production.

This site is an interactive, collaborative project that uses Google maps with you and your students to provide content. You can also see Math maps created by others. By following the directions, you can create math problems utilizing information from your own city or town. Once the math problems are posted on the map, you can tweet or blog to inform others about them. In addition to creating problems, your students can view the contributions of others and solve real world math problems. Be aware: pop-up messages do appear across the bottom of the screen. These messages are recent posts to the site. Teachers who wish to contribute must submit a Gmail address to be offered access to add their own "Maths Maps." (Note to U.S. educators and students: What you know as "math" is known as "maths" in the UK, Australia, and some other countries. The "s" is NOT a typo!)

tag(s): map skills (84), maps (298), measurement (175)

#### In the Classroom

What makes this site special is that the content comes directly from educators and students. Use the existing math problems as a challenge activity or to demonstrate how math can be used in the real world. Share the maps and math questions on your interactive whiteboard or projector. The different pin colors represent different age groups so you can choose appropriately leveled math problems. You can easily differentiate for individuals by telling them which color to explore. This site is a great way to get your students to learn more about their community. Have your students research a community spot and create a math problem about it as a class. Enter the information onto the map together or under teacher supervision for other classes all over the world to use. Allow students to explore on their own and keep a math log of all the problems they found and solved on a "trip around the world with math."

This creative website allows you to create a personalized snowflake (perfect for winter). It is the virtual version of construction paper and safety scissors snowflakes minus all the mess. Some visual and mechanical dexterity is still necessary, but not nearly as much as complex paper snowflakes require.

tag(s): snow (20), symmetry (51)

#### In the Classroom

This site would work well in an elementary art class as a winter project or when teaching about the seasons in primary grades. All of the saved snowflakes are assigned an ID number. The flakes can be downloaded as jpeg files, EPS files (to be manipulated in your own graphics programs), or emailed to you. Use downloaded images to create a winter "big book" along with winter poems by your young students. Use this site in upper grades in both graphic design classes as part of a winter webpage project or in a geometry lesson on angles or reflections. The website could be previewed on the interactive whiteboard or projector. Then students can create their own on laptops or in the computer lab. What an entertaining way to teach symmetry to younger students!

Challenge basic counting skills and problem solving using classic sliding puzzles. Not only will you find numerical sliding puzzles, but also colorful shape puzzles. Java applets make an interactive version of each puzzle appear below the "goal" you are trying to reach. There is also a targeted number of moves to reach the goal. There are many different types of puzzles, some more familiar than others. Be sure to be patient as puzzles load. Sometimes the interactive (drag to slide) portion does not appear right away.

tag(s): logic (248), puzzles (203)

#### In the Classroom

Share these puzzles on your interactive whiteboard (or projector) as a mind-bending challenge. Help students develop problem-solving skills such as thinking several steps ahead by offering the link on your class web page. Higher level and gifted math students can try to determine a formula for calculating the number of moves it may take to solve a puzzle. Give awards to students who accomplish the "goal" in the stated number of moves, then ask them to explain their strategy or think aloud as they repeat it on an interactive whiteboard. Offer a puzzle club for your mathematical/logical thinkers or simply develop visual thinking skills by sharing these challenges.
