Curated OER
Surface Area of Prisms
Students compute surface area and volume of prisms. In this surface area lesson, students find the surface area and volume of rectangular and triangular prisms. Independently, students use their computers to determine the volume,...
Curated OER
Investigating Area Using Tangrams
Tenth graders connect the history of geometry to problem solving. In this geometry lesson, 10th graders investigate polygons through hands on manipulatives and solve problems relating to parallelograms and triangles. They calculate the...
Curated OER
Around The Stop Sign
Learners analyze a drawing of a regular octagon inscribed in a circle to determine angle measures, using knowledge of properties of regular polygons and the sums of angles in various polygons to help solve the problem. They use...
Curated OER
Deductive and Inductive Reasoning
Students differentiate between inductive and deductive reasoning. In this geometry instructional activity, students identify congruent figures and examine logos for congruency.
Curated OER
Why Doesn't SSA Work?
Students investigate the relationship between angles and their sides. In this geometry lesson, students prove why SSA does not work as a true angle side relationship theorem.
Curated OER
Properties of Parallelograms
Students identify different properties of parallelograms. In this geometry lesson, students complete problems that proves the theorems and properties of parallelograms. They graph the different shapes on paper.
Curated OER
Around the World With Geometry
Learners identify shapes, create shapes, and make a pyramid, a drum, and a sail using their shapes. In this shapes lesson plan, students also identify plane and space shapes.
Curated OER
Parallel-o-Home
Students investigate the usage of parallel and perpendicular shapes in the real world. In this geometry lesson plan, students investigate shapes for properties that are related to the real world. They relate all the properties of shape...
Beacon Learning Center
Angles and Algebra
Young scholars calculate angle measure for triangles and complementary/supplementary angles. After a lecture/demo, students utilize a worksheet imbedded in this plan to gain practice.
Curated OER
What You See Is Not Always What You Get!
Students estimate and calculate the distance of a shape. In this algebra lesson, students differentiate between a horizontal distance and it's reflected image. They measure the reflection and the point starting at the eye of the observer.
Curated OER
What's The Point?
Students solve word problems using the correct math symbols. In this algebra lesson, students use the TI calculator to graph their equation and analyze it. They find the line of regression and use to draw conclusion.
Curated OER
Moving Straight Ahead
Learners analyze the relationship between speed, time and distance. In this math instructional activity, students plan a school trip. Learners determine the efficiency and cost effectiveness of a trip.
Pennsylvania Department of Education
Creating Polygons
Learners describe, make and compare polygons. In this creating polygons instructional activity, students identify properties of quadrilaterals and describe common features of two dimensional shapes.
