Radian Measure
Young mathematicians identify central angles, arcs and radius of circles in this pre-calculus lesson. They identify the proportion of the circle based on its radius while they convert between degrees and radians measurements.
Curated OER
Taylor Polynomials
Pupils graph Taylor polynomials in this calculus lesson. They observe the graphs for the expansion of Taylor polynomial functions and use the Ti calculator to help create visuals of the graphs.
Curated OER
Transformations: Translations
Students perform transformations and translations using polygons. In this geometry lesson, students perform transformations on a coordinate plane. They identify the image and pre-image of each figure.
Curated OER
Transformations and Rotations
Students define and identify transformation and rotation. In this geometry instructional activity, students define rotations as congruence or isometry. They find the coordinates of an image and pre-image.
Curated OER
Geometric Shape Cakes
Learners become problem solvers and communicate geometrical ideas. In this geometrical shapes lesson plan, students make a cake template from geometrical shapes.
Curated OER
Do the Twist...(Learning about Screws)
Young scholars investigate how screws are a twisted incline plane. They observe the teacher screw a screw into wood and participate in a class discussion. Next, they make and test a prediction about how the spacing of the threads on a...
Curated OER
Up For Change?
Students explore similar objects. They participate in a series of hands-on, multimedia and online activities to examine how the edge length affects the angle measures, perimeters and areas of similar regular polygons. Students find the...
Curated OER
Exploration with Geometric Solids
Students reinforce geometric concepts by playing "Guess My Solid." Through a process of elimination, they determine the shapes of mystery solids. Finally, students use various materials to construct their own geometric figures.
Curated OER
Finding the Sum of the Exterior and Interior Angles of a Polygon
Students find the sum of the angles of a polygon and construct a polygon given the number of sides. In this polygon lesson plan, students draw large polygons on the floor of the room. They measure the length of each side and the interior...
Think Map
Know Your Polygons!
Shape shifters recognize characteristics of polygons. Embracing language arts skills in addition to math, they use a thesaurus to pinpoint specific attributes of a set of polygons. They also participate in a 21-question guessing game...

Aztec Sun God Sculpture
Students create their own Sun God Sculptures. In this Aztec art lesson, students create their own Sun God Sculpture. After finishing the project sudents compare and contrast their sculpture to the pictures of the Aztec's sculpture.
Curated OER
Investigation So What's The Difference?
First graders investigate the differences between shapes. In this block characteristics lesson, 1st graders work in groups to explore blocks, group the blocks by different characteristics, discuss the block attributes and record...
Curated OER
Equation of a Circle
High schoolers write the equation of a circle. In this geometry lesson, students check the solution of a coordinate pair by evaluating them. They graph the circle given the equation and radius.
Curated OER
Transformations: Reflections
Students perform transformations on their graphs. In this algebra lesson, students identify the pre-image and image. They find and identify congruent shapes and isometry.
