Shmoop Pre-Algebra offers students an overview of basic operations, basic geometry, fractions, decimals, ratios, percentages, probability, and algebra including terms and additional websites. Interactives follow many topic overviews. The easy user interface will make it a favorite for students, though it is text-heavy in places.

#### In the Classroom

Add the site to your classroom computers' favorites (and a link on your class website) for students to use from home or when they need to review pre-algebra topics. Use the games as a classroom activity on an interactive whiteboard to test student knowledge or to prepare for a test. Use the summaries yourself to help organize your presentation of the content. Students can create accounts on Shmoop to access more features, but the site is very useful even without an account.

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.

Math Open Reference is designed to teach High School geometry and functions. The site is organized into modules by geometric topic with specific lessons for each concept. The main topics include Plane Geometry, Coordinate Geometry, Solid Geometry, and Tools (Math/Scientific Calculator, General Function Explorer, Graphical Linear Function Explorer, Graphical Quadratic Function Explorer, and Graphical Cubic Function Explorer). Each module includes interactive elements that allow you to experiment with the topic concept. The interactive activities make abstract concepts more concrete.

#### In the Classroom

Math Open Reference modules are effective in a lab setting or using an interactive whiteboard or projector with the entire class. Although the lessons are designed for High School students, some of the activities are appropriate for Middle School students. The ability to make and print custom graph paper is a very useful feature. Have student groups explain a geometric concept on the interactive whiteboard, putting the explanations in their own words. For example, have them use the congruence tools on this site, then draw examples using the whiteboard tools, challenging their classmates to identify congruent examples.

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 (50)

#### 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!
