Excellent lesson! Anne Linehane's geometry story, The Greedy Triangle, offers an opportunity to practice forming various types of polygons with your learners. Using elastic bands (or Chinese jump ropes),...

Students review angles, sides, and properties of basic shapes. Using a geoboard, they make as many different tirangles as possible.

Invite your first graders to compose and decompose two and three-dimensional figures with this fun, hands-on lesson. They investigate and predict the results of putting together and taking apart two-dimensional shapes with rubber bands...

Young scholars study a variety of geometric shapes by taking pictures of items representing the shapes with a digital camera. They identify the shapes by using software to paint on the image.

Students discover different geometric shapes such as triangle, square, rectangle, and octagon. Students incorporate the use of technology by taking pictures of shapes around their school using a digital camera.
