Fourth Grade - November 10th - 14th, 2008

Fourth graders will begin their geometry unit by studying the characteristics of polygons. They will look at shapes that are polygons and shapes that are not polygons. From their observations, students will decide what is true and untrue about polygons. Some characteristics of polygons include:

• It is a closed figure - there are no openings in the shape.
• It only has straight sides - there are no curves.
• The lengths of the sides don't have to be equal.
• It doesn't have to be a typical shape like a square or rectangle

Students will then extend their study to polygons with 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 sides.
