This site provides the opportunity to explore Venn Diagrams through the use of shapes. Different ways to create the diagrams are provided by choosing one or two circles and choices of circle placement. With the "Guess the Rule" option, players try to find the rule based on shapes that are allowed into the design. The learner area provides a background on Venn diagrams and how they might be used in everyday living. The instructor area provides printable exploration questions, links to standards, classroom preparation tips, and links to similar resources.

tag(s): logic (236), problem solving (272)

In the Classroom

Introduce this site on your interactive whiteboard or projector. Then have students explore this site independently or in small groups. Ask students to create their own Venn Diagram and have other students guess the rule. Consider using a site such as Interactive Two Circle Venn Diagram (reviewed here). Use the site to demonstrate Venn Diagrams that might be used with different subjects: Science - use to sort animals by different characteristics, Social Studies - sort countries by different types of rule over a given time period. The possibilities are endless.

Create a website map or mindmap easily with this free site. Create a login (requires an email address.) Add interest to your site as visitors choose a node and new options open up for them. Spicynodes is a mindmap but all portions are not displayed until they are clicked on, activating greater interactivity to your sitemap or mindmap.

tag(s): graphic organizers (42), mind map (24)

In the Classroom

Create a new map by entering the details such as a title. Choose from the template styles given. Preview the template, zoom in and out, and scroll around the mindmap using the simple tools. Click the "Edit Content" tab to change each node in your mindmap. Edit the name of the node, the description, and upload or link to a picture. Nodes can also link to a You tube video. When done, click preview to not only see the finished mindmap, but to publish on the Spicynodes site or copy the embed code for placing on a wiki, blog, or other site.

There are countless possibilities at this mental mapping site. Demonstrate the activity on an interactive whiteboard or projector, and then allow students to try to create their own graphic organizers. Use this site for literature activities, research projects, social studies, or science topics of study. Use this site to create family trees. Have students collaborate together (online) to create group mind maps or review charts before tests on a given subject. Create a site map that guides users throughout the features of your class website.

Collaborative Projects: Have small groups research together a topic such as unsolved mysteries of the world, planets, legends from their countries, plants, famous mathematicians, or any topic that can be broken down into parts. Each student would have their own node and color and would then upload pictures, videos, links, and other information they have found about their part of the topic. If the whole class is researching a topic, students with the "like" assignments could get together to share information and create their part of the small group node (also know as jigsaw in cooperative learning). Once all the nodes are completed, the original small group would share information with each other. There are a variety of ways students could use this mindmap. You could just leave it at the small group share out. Or, you could have the groups decide what information is important enough to present to the class and put their ideas on a Writeboard document reviewed here. A third step could be that once they've honed down the information, they could create a presentation for the class in a variety of formats: Glogster reviewed here, or Animoto reviewed here are only two of the many presentation formats we have reviewed on TeachersFirst.

Student project ideas: Have students... organize any concepts you study; color-code concepts to show what they understand, wonder, question; map out a story, plotline, or LIFETIME; map out a step-by-step process (life cycle); map a real historical event as a choose-your-own-adventure with alternate endings(?) based on pivotal points; plan a "tour" for a "thought museum."

Use this mapping website as an alternative to a traditional test, quiz, or homework assignment in literature or social studies: have students demonstrate their understanding by completing a graphic organizer about the main points. Be sure that they RENAME it before they start work to an individual name so you know who did it (they could EMAIL it to you!) or have them print their results to turn them in.

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 (289)

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.

The simplicity of this online slide presentation tool can be used by anyone! SlideBoom is an online presentation share and store site. The site is somewhat "vanilla" in that there are not a lot of extras or flash, however in some situations it may be very handy. Access other people's slide presentations and share your own with the world. This is the free version, so its capabilities are limited. But it would be great for kids to use to move presentations back and forth between school and home if Google applications are blocked.

tag(s): images (271), photography (160), slides (65)

In the Classroom

Users must be able to locate files on their computers to upload. Beyond that, a few clicks that follow onscreen instructions will complete the job!

Use this site as transportation to and from school when students are working on powerpoint presentations for class. This tool could be used in any subject or topic area. If Powerpoint isn't available at your school, use this site to create presentations instead of traditional book reports. Use this tool in social studies to have students create presentations about the branches of government, continents, or economics. The possibilities are endless.

This site provides great practice for Bidmas (Brackets, Indices, Division, Multiplication, Addition, Subtraction) and order of operations. Virus infected robots are trying to eradicate humans and the only way to stop them is to deactivate their shields by solving problems correctly. Move up through levels to increase the difficulty of problems. This game can be played for free; in addition, teachers can sign up for an account (for a fee) so that student scores can be saved. Be sure to check out the Achievements section which lists math skills incorporated at each level.

Be sure to provide this link on your website for students to access both in and out of the classroom. You will want to turn down the sound, even if students wear headphones, so you do not damage hearing!

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 (128), statistics (123)

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.

This site provides practice with creating and exploring tessellations. Choices are provided to use triangles, rectangles, or hexagons. Once a shape is chosen, the corner can be stretched to create a new shape. Click a button and that shape is converted into a tessellation in front of your eyes! Choices are also provided for different colors within the shapes to enable visualization of how the pattern is created.

The learner portion of the site provides a written explanation of tessellations and information on how they are found in the real world. Be sure to visit the instructor link on the website for information on classroom use, links to standards, links to similar resources and to print an exploration questions worksheet.

In the Classroom

Use this site as an anticipatory set or "activator" to introduce a unit or lesson on tessellations on a projector or interactive whiteboard. It relates well during study of flips, turns, and rotations as well as visual thinking. Introduce this site and then have students complete the exploration questions independently or in small groups. After students become familiar with tessellations, use examples on the site and have students create their own tessellations.

This site provides practice with identifying patterns using a table and chairs visual. Practice involves exploration, where the student chooses the length and arrangement of the table (straight line or rectangle) or guess based on the random image generated. Be sure to check out the in-depth explanation on the learner portion of the website. The instructor area includes a description, links to standards, classroom information and links to similar resources. Exploration questions can be downloaded for classroom use.

tag(s): equations (155), logic (236), patterns (85), problem solving (272)

In the Classroom

Introduce the site on your interactive whiteboard or projector by beginning with the learner section of the site. Discuss the different arrangements of tables and chairs and how seating capacity changes based on table arrangements. Allow students to complete the exploration questions on their own or with a partner. Provide a link on your classroom website or blog for students to use at home. Challenge able students to create pattern challenges of their own for classmates to try on an interactive whiteboard using shapes and colors.

This activity allows the user to estimate quantities and sizes including the number of objects in a set, the lengths of a curve, and the area of a shape. Many options are available for exploration - the size of the curve can be changed, problem type can be changed and there are 2 levels of difficulties. The learner section explains the activity as well as discusses how estimation is used in everyday life. In addition to a description of the activity, the instruction section provides possible issues to address in the classroom, links to standards, and links to other similar resources.

tag(s): estimation (45), measurement (160)

In the Classroom

Introduce the activity on the interactive whiteboard or projector and model for students how to use estimation instead of actually counting the figures. Use the site as a springboard to discuss when estimation is appropriate and when measurement is needed. Use the site to begin discussions on what level of estimation is needed in different circumstances (close, really close and almost perfect).
