Angles
In this game students change the angle of a sprinkler to squirt various objects around the screen. Objects are located at 45 degree intervals around the radius of the sprinkler. There are guiding questions asked at the top of each screen to help students determine the angle that needs to be set. Fun animation and sound effects.

What's My Angle?
A series of TEN activities involving measuring and estimating angles up to 180 degrees. An interactive on screen protractor is provided for many of the activities.

Angle Shapes
Twenty activities that involve measuring angles inside various geometric shapes. Guiding questions to start a discussion about the relationship of shapes and angles.

Geoboard: Circular
There are several activities involving angles inscribed in a circle. Triangles are also created and angles determined. Instructions for each activity automatically appear, but if they are accidentally closed, you may reopen them by clicking on the "Activity" button at the top of the window.

Banana Hunt
In this game students are awarded "bananas" based on the accuracy of their estimates of various angles. The closer they are the more bananas they earn. Fun animation and sound effects.

Carnival Game Students estimate the angle of rotation needed to fire a cannon at a target. They have 10 balls to hit as many targets as possible. On a SMARTboard you will use the onscreen keyboard to enter the numbers in degrees.

Angle Measure
ANOTHER great resource from TeacherLED, a site created by Spencer Riley, a teacher in Birmingham, United Kingdom. You can create angles of various sizes, and then demonstrate how to measure them using either a 180 degree or 360 degree protractor. What I think you will find especially helpful is that the protractors are automatically centered on the vertex of the angle.

Alien Angles
A great game for estimating angles. To rescue 10 aliens, you must set the rescue launcher to the given angle. You must be accurate to within 5 degrees to be successful.

Quadrilateral Quest This interactive site has multiple levels and criteria for identifying various types of quadrilaterals. Students are presented with descriptions of the angles and sides and they must place the correct shapes into the checking bin. There is lots of audio and video feedback. After completing 7 levels the students take an interactive quadrilateral quiz.

Bearings Bearings is a great site for estimating angles. You may choose to work with angles in 90 degree increments, or from 0 to 360 degrees. You may also use a protractor on this site if you choose. There is also a PDF/DOC with real world examples of navigation.

Virtual Pinboard There is so much to do here! This Geoboard allows one to create shapes with any number of vertices, color the shapes, measure with a ruler or protractor, add labels to any part of the drawing, and you can even print your creation. Use may use centimeter paper, or a triangular grid as your background. This is a must see!

Measuring Angles Students create angles, then use a proctractor to measure the angles. The students fill in a box with their measurement of the angle and click "Check." The site responses by telling the student if they are "too big," "too small," or "perfect."

Exploring Complementary Angles Another interactive lesson from LearnAlberta that teaches students about the properties of complementary angles. Focuses a lot on the importance of 90 degrees.

Virtual Pinboard There is so much to do here! This Geoboard allows one to create shapes with any number of vertices, color the shapes, measure with a ruler or protractor, add labels to any part of the drawing, and you can even print your creation. Use may use centimeter paper, or a triangular grid as your background. This is a must see!

The Eyeballing Game What a fun site! You are presented with several puzzles: Parallelogram, midpoint, bisect angle, triangle center, circle center, right angle, convergence. You must "eyeball" and then click on the location of the screen that you believe to be correct. The correct location is then given, along with the distance from that spot to your guess. As in golf, a lower score is better. Oh, and by the way, the clock is running, so speed is also a factor. You have 3 chances at each of the puzzle types, after which you are given a final score. Your score is then plotted against the previous 500 scores others have made. What a great way to practice estimation, and if you capture each puzzle to a Notebook file you'll be able to actually measure the distances and angles yourself.

Bisection
This site shows how to bisect an angle or line. There are also some real world application problems where students need to bisect angles on a soccer field or baseball diamond. These problems use realistic graphics and interactive input.
