Curated OER
Triangles with Collinear Circumcenters
Pupils identify the circumcenter of a triangle. In this geometry lesson, students construct a perpendicular bisector using a straight edge and a compass. They differentiate between triangles and collinear points.
Curated OER
The Price Is Right
Students create a list of products with estimated prices. In this algebra instructional activity, students learn to write equations using variables. They match their created list with that of actual products and compare their prices,
Curated OER
Angle Action 1,2 and 3
Young scholars investigate angles through construction. For this geometry lesson, students use a protractor to identify the measurement of an angle. They identify angles cut by a transversal and two parallel lines.
Curated OER
Pyramids- Slant Height and Altitude
Students calculate the height and altitude of a pyramid. In this geometry lesson, students define the parts that make up a pyramid. They use the Pythagorean Theorem to find the missing parts of a pyramid.
Curated OER
Sketching Prisms
Students sketch and create nets of different polygons.In this geometry lesson plan, students differentiate prisms from other three-dimensional shapes. They define the properties of prisms.
Curated OER
Typhoon Project
Learners graph and outline the path of a typhoon. In this algebra lesson plan, students measure the path of the typhoon and create a graph with their data. They analyze the data and make predictions.
Curated OER
The Sum of All Angles
Young scholars add up the different angles using the angle addition postulate. In this geometry instructional activity, students differentiate between interior and exterior angles. They calculate the different angles for triangles and...
Curated OER
Geometric Figures
Learners identify two and three dimensional shapes and use appropriate geometric vocabulary to write a description of the figure by taking pictures of geometric figures in their own environment.
Curated OER
Simply Similar at Sea: Simple Triangles
Tenth graders answer a variety of problems based on similar triangle and learn about the rule of thumb. They will test the rule of thumb by estimating the distance to an object in the classroom.
