How To Use A Protractor
Fifth graders use the SMART Board to demonstrate how to use a protractor to measure acute, obtuse, and right angles. In this protractor lesson plan, 5th graders also complete an angles worksheet.
Curated OER
Triangle Puzzler
Students are introduced to some basic concepts of geometry. They explain that the definition of a triangle is a figure with three sides, three angles, and three points. Triangles can be named by using three points in their correct sequence.
Curated OER
Clockwise
Second graders investigate angles through this series of lessons. They determine how angles turn in both clockwise and anticlockwise directions. They examine the characteristics of quarter half turns and how they can begin from any...
Curated OER
Area Lesson Plan
Students explore geometry by using computer applications. In this spatial measurement lesson, students discuss the difference between area, weight, volume and other forms of measurement. Students utilize computer applications to find the...
Curated OER
Lesson Exchange: Polygons (Middle, Mathematics)
Students discover the relationship between the sides of a polygon and the number of diagonals that can be drawn from one vertex, the number of triangles that those diagonals form, and the sum of the interior angles of that polygon.
Curated OER
Geometry for the Technologies
Young scholars discover how to use various tools to measure and draw angles. With protractors, they classify angles according to angle measure, identify vertical angles, and perform angle additions. For their final project, students...

Perfection on Ice!: Math, Geometry, Fibonacci Numbers, Olympics
Students use the human body as a foundation for gaining practice in measuring angles and calculating ratios and proportions.
Curated OER
Noon Project Revisited
Students, just like Eratosthenes, try to use math to calculate immeasurable objects. Teachers need to try out the calculations before having your class do them. They should take notes to be included with their own calculations and drawings.
Curated OER
Physics Lab Rockets
Students construct and test balloon rockets and a model rocket. In this rocket science lesson, students use an inquiry-based method to master balloon rockets and have a shoot-off with the goal of attaining the highest altitude. Next,...
Curated OER
Pythagorean Theorem
Students identify a right angle and right triangle. They perform WebQuests searching for similar figures and solve for the length of one of the sides given the other two.
Curated OER
Intro To Quadrilaterals
Students engage in a lesson plan that is concerned with the concept of quadrilaterals and how they are used to create a rectangle for a door. They create a drawing of a quadrilateral while finding the sum of the angles. They practice...
