Hexagon Island
Young scholars identify different polygons. In this geometry instructional activity, students name polygons using the number of sides. They calculate distance and slopes using the correct formula.
Curated OER
Diagonals to Quadrilaterals II
Students identify the properties of different polygons. In this geometry lesson, students find the slope of a line and calculate the distance between two lines. They differentiate between similar and congruent polygons.
Curated OER
Line, Ray, Segment
Students define vocabulary words. In this geometry lesson, students identify the graph as a line, ray or segments. They understand the properties of each and calculate the distance on a number line.
Curated OER
Skateboard Flex
Students examine statistics by completing a skateboard measuring activity. In this flex lesson plan, students define what skateboard "flex" refers to and identify the proper method of measuring flex by conducting an experiment with...
