This site provides a good way to practice vocabulary words. Knoword is a vocabulary game that requires you to think quickly on your feet. You will be given one randomly generated dictionary definition along with the first letter of its corresponding word. The object of the game is to fill in the rest of the word. The faster you guess the word the more points and time you'll receive. Don't know the word? Just hit the skip button and a new definition will appear. You can create an account if you want to save your scores. Creating an account does require an email address. Note that you can change which English spellings used (U.S. or Canada/Britain) by clicking the small flag at top right. The speed and variety of words builds general verbal accuity and flexible thinking along with specific vocabulary.

tag(s): test prep (96), vocabulary (318)

#### In the Classroom

Introduce this site on your interactive whiteboard or projector. Then have students explore this site independently or in small groups. Put this on classroom computers or on a whiteboard at the side of the classroom for students to use as a center. This game would be great for students preparing to take SATs. Another activity is to have a team competition. Divide your class into three or four groups and give each group a laptop. Have them work together to see how many words they can type. Before you begin be sure that you change the language to English US because it defaults to English Canada/Britain. Have a team tournament for high scores throughout the year. Gifted students -- even very young ones-- will love this challenge.

Tip: rather than using your personal or work email, create a free Gmail account to use for memberships (if you decide to register). If you plan to have students register individually, you may want to create your own Gmail account with up to 20 subaccounts for each group of students (by code name or number) within your classes. Here is a blog post that tells how to set up GMail subaccounts to use for any online membership service.

Harcourt School's website offers many different activities for practicing Math skills taught in their 3rd grade program; however, the activities are free and useful for everyone, no matter what text they use. Activities are divided by math strands - number sense, algebra and functions, measurement and geometry, and statistics, data analysis and probability. Most activities have an interactive element and printable recording sheet that can be used by students. Students can input their own figures which makes the activities less repetitive and more interesting.

tag(s): data (159), multiplication (210), probability (138), time (141)

#### In the Classroom

Make a shortcut to this site on classroom computers and use it as a center. Use this site to differentiate for students of all levels. Have students complete the recording sheet with an activity to use as an assessment or accountability piece. Include a link to the site on your classroom website or blog for students to practice at home.

Put On Your Thinking Cap as you enter Flossville Town Park and Windjammer Environmental Center! Students are encouraged to think critically and problem solve as they encounter unique geometry and measurement challenges at this highly interactive website. How does it work? As students work through the tasks, they can access hints to help them along. These hints are brief math tutorials with explanations and examples. At any time, students may check their work to get feedback on how they are progressing. When students successfully complete a task, they are asked to "Make the Math Connection." This additional question was designed to reinforce students' knowledge of the math concept and provide another opportunity for students to apply their knowledge. Students can sign in to save their work. No email address is required to sign-in/register. Registering is especially helpful if a planned project takes several days. Students can also view "Math in Action" videos to see how people such as architects and cake designers use geometry and measurement concepts everyday in their jobs.

Be sure to visit the Teacher Resources section which includes standards, lesson plans, tips, and math in action videos.

tag(s): critical thinking (117), measurement (171), problem solving (289)

#### In the Classroom

Introduce the site on your interactive whiteboard or projector then allow students to explore on their own. This site is perfect for independent projects - students can create a multimedia presentation of information learned through the challenges, respond through journal entries over several days, or use this site as a resource day for career day projects. Include a link on classroom computers for students to use during free time.

This site contains many visual explanations of Math topics including interactive practice activities. Each explanation begins with a definition of the topic (such as adding or subtracting fractions), then moves on to practicing the skill with the interactive pieces. Practice activities at the end of each topic are very visually appealing and will appeal to most students. One of the most useful portions of the site is the glossary which contains definitions of many Math terms along with examples of the terms in use.

tag(s): charts and graphs (198), fractions (226), integers (41), puzzles (207), statistics (125)

#### In the Classroom

This site would be useful for students to practice skills already learned; however, the explanations are not in-depth enough for beginning to learn concepts. Create a link on classroom computers or in the computer lab to use as practice. Use the glossary as a resource on your interactive whiteboard or projector when definitions are needed for math terms. Provide a link on your class website or blog to the glossary for students to access at home. Display the site on your interactive whiteboard, choose a subject such as adding/subtracting fractions, then click the link titled "topic" and choose the final item in the sequence - in this instance it is an activity called The Small Flood. These activities are perfect for whole-class practice in each subject.

This site provides tutorials and free puzzles for the game of KenKen. KenKen is similar to Soduku; however, it has the added complication of requiring number combinations (using operations such as addition, subtraction, multiplication, and division) to fit within bolded boxes. The site has an excellent illustrated tutorial on how to play the game located at the "How to Play" link. Teachers can sign up for the free newsletter and receive free puzzles. There are several free puzzles on the site. Much of the site is devoted to selling puzzle books (so you will notice some advertisements); however, there are many free puzzles and the tutorial makes it worth a visit. Also available is an iphone app that can be downloaded to receive more puzzles.

tag(s): addition (224), division (159), logic (242), multiplication (210), puzzles (207), subtraction (184), vision (77)

#### In the Classroom

Review the illustrated tutorial on your interactive whiteboard or projector when showing students how to play KenKen. After students understand the game, create a link to the free puzzles on classroom computers or the computer lab for students to solve.
