If you were not in class, or you wish to review what we did in class, you should read the article Learning Geometry from the content section of D2L and take notes on:

• What children find problematic about the definition of triangles
• Difficulties children have with squares and rectangles, and especially the relationship between squares and rectangles.

You should also read about special kinds of triangles and complete the table showing the 7 possible combinations of triangle properties (the table itself has 9 places where triangles can go, but only 7 of them can be filled with triangles--the other two represent impossible combinations). I will be checking notes for this completed table and recording a score for this as an assignment.
