Proving Quadrilateral Properties
Working backwards can sometimes help you see a path to solving a problem. In this chapter, properites of quadrilaterials are proven by looking at flowcharts and working the probem backwards. Worked through examples are given, along with...
Curated OER
Geometry Flip Book
Students investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed and...
Curated OER
Geometric Relatioships
Students explore measurements and geometric formulas. In this geometry lesson, students investigate pi as it relates to geometry. They collect data and use a chart to organize the data.
Curated OER
Geometry
In this line and angles instructional activity, students explore basic geometry vocabulary. They classify polygons. Students determine the area and perimeter of given shapes. They examine the parts of a circle, find volume and surface...
