2-D Shapes Websites


K-2

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!

Castle Shapes Another great site for identifying and classifying 2D and 3D shapes. A downloadable lesson pack contains worksheets that replicate the on-screen activities, and flash files so that the activities can be used offline as well. There are 5 different activities in all.





3-5

Shapes in Space There are 4 levels of increasing difficulty in this game. Students identify 2D and 3D shapes, discriminate polygons from non-polygons, and attributes such as edges, sides, faces, and vertices. Very colorful with lots of sound effects, and even a arcade game-like bonus round.

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.

Perim-Bots Students get a lot of experience with measuring and calculating perimeter in this fun site. They build a robot by receiving parts each time they answer a question correctly.





6-8

Enlargements On the first level a variety of shapes and objects are displayed in two different sizes. By manipulating the size of the grid, students are able to determine the scale factor by which the object was either enlarged or reduced. The second level presents students with a shape that they must enlarge to a given scale. This "flexigon" has vertices that may be dragged in any direction. There are also worksheets for each activity.
