Geometry teaching strategies
Here are links on different teaching strategies for geometry to use in your classroom! Please click!
Strategy 1: To set up proportions and solve for missing sides of the similar figures students will use 3 dimensional unit cubes as manipulatives. Students use tracing paper to draw 2 dimensional shapes then convert these shapes to 3 dimensional using the unit cubes. This may also be seen using a SmartBoard. Using the 2 dimensional paper students draw what their 3 dimensional shape looks like onto it to show the relation in unit cubes. Students then cut open cylinders. prisms, cones, and pyramids into cross sectional views to see what shapes they are made out of. Here is a link that shows the effectiveness of this strategy. http://educationforatoz.com/images/2_Chew_Cheng_Meng.pdf
Strategy 2: There are 5 developmental levels of geometric reasoning. They are, Visualization, Analysis, Informal Deduction, Deduction, and Rigor. These levels are discussed and learned through manipulatives (geostrips/fasteners/tag board), the jigsaw method, similarities and differences using venn diagrams, and vocabulary enhancement. Here is a link to show the effectiveness of these strategies. http://www.sciencedirect.com/science/article/pii/0004370294000648
