Stretching the Quads
Explore parabolas in this algebra lesson with the graphing calculator. The class investigates what effects the changing of the parameters of the vertex form of a quadrati have to its graph. They find the zeros of a quadratic graphically...
Curated OER
A Cone and Its Net
Create and investigate nets for solid shapes with your class. They identify the different parts and faces of each polygon and solid then calculate the surface area and volume of cones. They use circle sectors of varying sizes to build...
Curated OER
A Rectangular Prism and Its Net
Identify the nets for prisms and other geometric shapes. Learners calculate the surface area of the rectangular prism then sketch the shapes of prisms and other polygons. Unfolded cereal boxes are used as a visual aid, great idea!
Curated OER
Volume of Cones
Students identify the volume of cones and pyramids. In this geometry lesson, students derive the formula for cones and pyramids. They calculate the volume of cones and other three dimensional shapes.
Curated OER
Volume of Cylinders
Middle and high schoolers calculate the volume of cylinders. In this geometry lesson, learners differentiate between rectangular prisms and cylinders. They use the correct formula to solve for each solid.

Tell Time to the Nearest Half-hour and Relate to Events
Youngsters examine how to tell time to the nearest half-hour. They discuss why people wear watches, listen to the book "What Time Is It?" by Sheila Keenan, view examples on a model clock, and complete a worksheet with the teacher.
Curated OER
Volume of a Rectangular Prism
Children use the length, width, and height of an object to calculate the volume of a rectangular prism. They observe how to multiply three numbers at a time, and define volume. Pupils observe as the teacher demonstrates how to determine...

3-D Figures Part 1
Elementary schoolers explore 3-D shapes. They transition from thinking of shapes as only 2-D. Pupils read Cinderella as a launching activity for their upcoming adventure, and explore a new world of 3-D shapes in this introductory lesson.
Curated OER
Halves And Fourths
Young learners start out by going to the board to draw lines through shapes to identify halves. Then they are given a square of paper and are directed to fold the paper into halves and then into fourths. They color the halves...
Curated OER
Trace a Face
Students find two dimensional shapes in three dimensional figures. They determine the shapes that make up the faces of three dimensional figures of common classroom objects such as crayon boxes.
