Hexagon Island
Students identify different polygons. In this geometry lesson plan, 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 plan, students find the slope of a line and calculate the distance between two lines. They differentiate between similar and congruent polygons.
Curated OER
Egyptian Weather Lesson
Young scholars chart temperatures in Egypt on spreadsheet to determine how weather conditions affect lifestyles.
