How High did My Rocket go?
Students shoot off a rocket and measure the trig ratios relation. In this geometry lesson, students practice using an inclinometer to figure out how high their rockets fly. They measure angles and height and relate it to gravity and...
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.

An Introduction To Quadrilaterals
Young geometers investigate and apply properties of quadrilaterals. After a review and discussion of key terms, learners use a computer applet to explore four-sided figures and classify them according to their attributes. The...
Curated OER
True North, Magnetic North
Students explain why compass angles need to be corrected for regional magnetic variation. They observe the difference between magnetic and true north. Each student measures the angle of variation for a town in a different state.
Curated OER
The Right Time
Young scholars compute and estimate using mental mathematics, paper-and-pencil methods, calculators, and computers. They measure and compare quantities using appropriate units, instruments and methods. They utilize worksheets imbedded in...
Curated OER
What is a River?
Students study the various types of bodies of water: rivers, oceans, lakes and ponds. They observe models of each and then use clues to discuss how they are alike and different. They imagine they have found a new planet and draw a map...

Lawn Mowing
This is how long we mow the lawn together. The assessment requires the class to work with combining ratios and proportional reasoning. Pupils determine the unit rate of mowers and calculate the time required to mow a lawn if they work...
Curated OER
SAS Similarity Theorem
Learners identify and use the similarity theorem. In this geometry lesson, students differentiate between congruent and similar triangles. They solve problems using the computer modifying shapes by dragging.
Curated OER
Pythagorean Theorem
Students find the different ratios of a triangle. In this geometry lesson, students use the Pythagorean Theorem to solve for missing sides and angles on a right triangle. They use a robot to create a right triangle.
Curated OER
Triangle worksheets
In this geometry learning exercise, 10th graders explore triangle properties, including the sum of the measures of the angles of a triangle, the triangle inequalities, properties of isosceles triangles, properties of congruent triangles,...

Problem Solving Using Power Polygons
Students investigate geometric shapes by creating figures on a plane. In this polygon lesson, students complete a worksheet based on the angles in a power polygon. Students identify the different types of polygons and define their...
Curated OER
Strongest Polygon
Students define and identify shapes by name. In this geometry lesson, students construct, identify and compare polygons based on the number of sides. They classify each shape based on their angle sum theorem.
Curated OER
Are you in Golden Shape
Students solve and verify the solution for unknown measures. In this geometry lesson plan, students identify the properties of circles. They use the arc, angle and segment relationship to find the missing measures.
Curated OER
Related Robots
Students solve problems using implicit differentiation. In this calculus lesson, students take the derivative to calculate the rate of change. They observe two robots and draw conclusion from the data collected on the two robots.
Curated OER
Gazebo Construction
Young scholars create and give oral proposals for the construction of a gazebo using a blueprint created with Geometer's Sketchpad. They then build a gazebo model using the blueprints created and provide evidence why it should be...
Curated OER
Parts of a Circle
Sixth graders use yarn, paper plate, and other materials to identify parts of a circle. In this parts of a circle lesson plan, 6th graders identify the circumference, radius, diameter, and other parts of a circle.
Curated OER
Spiders' Wheel
Students engage in a lesson which reinforces the concepts of clockwise and anti-clockwise rotation, while developing an understanding that angles are measured in degrees. They utilize a mathematics educational program to gain practice.
Curated OER
Fashion Day
Eighth graders practice using basic measurements to solve word problems.They also investigate finding the perimeter of different polygons and define the characteristics to classify the shape as a polygon.
Curated OER
Symmetry
Sixth graders explore symmetry and discuss the difference between a rotation and reflection. Using hands-on activities, such as folding paper shapes, they discover how to find the lines of symmetry and symmetrical characteristics. As a...
