This interactive Flash game, played on a dot grid, offers an opportunity to practice visualizing squares and angles and also encourages students to use systematic strategies. The object is to select the four corners of a square in some size and orientation. The student can play against the computer or with another student. The dimensions of the grid can be adjusted. The student can opt to see the outline of a square once formed. The Teachers' Notes page offers suggestions for implementation, discussion questions, ideas for extension and support, and links to related activities.
