Tripline is a great visual for putting stories on a map. It was built to work with Google Maps, then be enhanced by each individual to fit their needs. What a fabulous way to integrate literature and geography, history and geography, or many other subject areas. To create a trip, type in a starting point and select it from a suggested list of matching places. Add places to your trip in the same way, places can be rearranged in any order. From this list, a map will be created showing the itinerary. Push play and the map comes to life, stopping at each creation point. To further enhance the experience, pictures can be uploaded that will show as icons as each stop is reached. Maps can be shared with other users, via email, web link, or Facebook.

To create a new trip, you must register at the site. Registration requires a username, password, and valid email address.

tag(s): maps (292)

#### In the Classroom

Suggested uses on the Tripline site are to use along with moments in history such as Paul Revere's ride and Lewis and Clark's expedition to demonstrate stops along their path. Other classrooms uses would be for students to create a Tripline map of their summer vacation to use as an enhancement to a regular report, map out your favorite sports team's schedule, historic state sites, and much more.

Registration does require an email address. Tip: rather than using your personal or work email, create a free Gmail account to use for memberships. 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.

This applet provides great opportunities to explore experimental and theoretical probabilities by changing the area of the colored regions of the circle. When a section is added it reduces the other sections by an equal amount in order to add the new sector. When this occurs, the probability that that particular color will be landed on will change. The number of sections of the circle can be changed from 1 to 12, as each spin is made, the color is recorded along with the percentage of time each color has appeared.

Be sure to visit the learner section of the site which contains a nice description of probability and how it is used in the real world. The instructor section also has a lot of valuable information including links to standards and textbooks, classroom information, and related resources. In addition, there is a link to a printable sheet of exploration questions to be used with the site.

tag(s): probability (135), statistics (125)

#### In the Classroom

Introduce this site on your interactive whiteboard or projector. Then have students explore this site independently or in small groups to complete the exploration questions. Create a link on classroom or lab computers for students to explore the site independently. Create a link on your classroom website or blog for students to explore the site at home. Have students create their own probability circles and record results of spins, then compare with classmates' findings.

Use this very simple site to create a test that's accessible on the Internet. Create an automatically graded test easily and for free! Registration is not required to use or to take the created tests. Simply click "Create a test," enter the test name, and create a password. Note: Be sure to remember the password somewhere because it is not possible to recover it. Read the directions on the Test Control Panel to adjust settings, add questions, and publish the test. Bookmark the URL of the finished test you make so you can find it later. After publishing, copy and paste the URL of the test into a wiki, blog, or site, for student access. View reports when students are done with the test.

tag(s): quiz (84)

#### In the Classroom

Skills required: Be sure to remember the password for your tests, as well as the unique URL. It would be wise to copy/paste them into a document you keep somewhere for reference. Users are unable to access the tests without the URL. Be sure to not share this ahead of time. Items in Testmoz are not made public.

Use where automatically graded tests are required, such as for formative assessments to check student understanding. Use as a "ticket out the door" to see what students know at the end of class. Be sure that this is the medium you want to use for testing. Be flexible with students who find it difficult to take online testing. Entering all the material ahead of time can be time consuming, so this may not be the best format for long tests. Use this quiz application to create study quizzes for review for students to complete as homework (or during class time). Have students rotate to create daily check quizzes for their peers (earning a grade for test-creation). Learning support students and others who need a little extra review might like to make quizzes to challenge each other or themselves. Have students who are preparing to give oral presentations in any subject prepare a short Testmoz for their peers to take at the end.
