Arcs and Angles
Noah didn't construct this kind of arc. High school scholars first explore how angles can be formed in circles. They then learn relationships between angles and arcs by conducting an exploratory activity where they position and draw arcs...

Expository Writing in Math
Pupils engage in an activity where one partner reads directions while the other follows those directions to complete a math task (such as bisecting an angle). As a reflection, they examine products to see what information the best...

Law of Sines
Laws are meant to be broken, right? Learners derive the Law of Sines by dropping a perpendicular from one vertex to its opposite side. Using the Law of Sines, mathematicians solve for various parts of triangles.

Introduction To Scale Drawings
Real-life math is really great! In groups, learners measure objects in the classroom. After comparing measurements, they determine a scale and create a blueprint of the classroom. They discuss the purpose of using scale drawings in...
Curated OER
Tangrams
Students construct tangram pieces. Then they make observations and explore patterns with the pieces.
Curated OER
Geometric Transformations
Learners solve problems involving transformations of geometric figures. They review graphing points in the coordinate plain, plot points and connect to create a triangle. Then, they reflect triangles over the x and y axis and use...
Curated OER
Investigating Volume
Learners investigate the components of volume and use appropriate units and procedures to calculate the volume of several household boxes.

DEAD MAN'S CURVE
Ninth graders, after being given a unique scenario and a task sheet on Dead Man's Curve, calculate and explain the force needed to keep a car on a curve using a set of formulas and a geometric property of circles. They utilize and create...
Curated OER
Finding The Area Of Shapes
Fourth graders investigate the concept of computing the area using different shapes. They use prior knowledge in order to devise a formula for a parallelogram. Scaffolding is provided by the teacher to find the formula of area for...
Curated OER
Precision Tools
Students discuss the appropriateness of using a specific tool to measure and define an object. After measuring the area of their classroom and the objects in it with the appropriate tools, they create a floor plan that makes the most...
Curated OER
Refining and Reasoning Behind Scale Drawings
Learners discuss accuracy and the need for it in blueprints in order to create the final project. They further refine and perfect drawings as part of the school drawing project. Students create a blueprint for the new school building...
