Parents Mastery of Geometric Concepts and Relationships Through the GeoLeg Program, a five-step method has been developed that leads to mastery of geometric concepts. We recommend that you use this five-step process to fully engage students in the learning process. Learning becomes deeper and more lasting. The goal of this five-step method is to take students from the exploration stage to describing the concepts and relationships using albebraic expressions or equations. 1) Explore by building with GeoLegs Use one or more GeoLegs as a hands-on circle or to build lines and polygons for visual and spatial exploration of relationships and concepts. Students how have the complete polygon with all interior and exterior angles. Or they can work with intersecting lines to see vertical and supplementary angle relationships. Encourage exploration with tasks such as "Can a triangle have more than one right angle?". 2) Observe measures and relationships Skills are developed as students observe measures of sides and angles and their relationships. Students can compare the change in angle measures in a triangle as the opposite side is increased and decreased. They can observe angle differences and similarities between isosceles and general trapezoids. Encourage predictions. 3) Draw figure and record measures By drawing the shapes and recording lengths and angle measures of the built figures, students have the opportunity to determine definitively angle-side relationships, perimeters, properties and other relationships. Drawing and recording increases observation skills. 4) Form conclusions about concepts After figures have been built, observed and drawn ask students to draw conclusions about relationships. This step gives them the opportunity to anticipate theorems and concepts. Remind them that any one exception is an incorrection conclusion. 5) Write expressions or equations Take your students through this final stage that demonstrates their understanding of relationships and equalities. By writing the expression or equation, students have bridged the concrete measures to an abstract concept. The GeoLeg Program offers three levels of instruction: Elementary, Middle, and Secondary Each level is based on the National Standards. The primary goal of the GeoLeg program is to help students develop geometry relationships and measurement connections between circles, angles, polygons and solids and to apply these concepts to everyday life.
