Curated OER
Area-Time to Get in Shape
Young scholars investigate the properties of triangles and parallelograms. For this geometry lesson, students calculate the formula used to find the are of a triangle and other polygons. They create a visual model to represent their...
Curated OER
Properties of Special Parallelograms
Learners identify properties of trapezoids. For this geometry lesson, students are put into groups and use computer programs to analyze polygons. They drag and move the shapes around as they make predictions.
