Volume Worksheet I
In this volume worksheet, students recognize three-dimensional figures, identify the proper volume formula, and then solve the equation by inserting information from a diagram into the formula. Students solve six equations.
Curated OER
Shape Up!
Students investigate measurement through the use of literature through this series of lessons.
Curated OER
Geometry: Calculating Volumes
In this volume worksheet, students find the volume of 8 prisms. Students are given the length, width, and height of each prism.

Houses
Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...
Curated OER
Geometry and Measurement
Young scholars view a right triangle displayed by the teacher. Students measure legs and the interior angles of the triangle. They look for a pattern or relationship between the legs and angles. Young scholars use pegboards and string to...
Curated OER
Three-Dimensional Figures
Sixth graders explore three-dimensional objects. Using various objects found in the classroom, they identify faces, edges, and vertices of objects. Students create their own objects. They describe the polydron, telling the faces,...
Curated OER
Polygons and Plane Figures
Pupils choose a polygon to define and describe, and use Power Point and the Internet to present their polygon.
Curated OER
Guess My Shape
Learners play a game with shapes. They work in groups to identify the names and characteristics of various shapes. They give each other clues to see if others can identify the shape being described. This is a great hands on activity.
Curated OER
Children's Museum of Houston - Pre/Post Classroom Activities - Nets
Students make three dimensional shapes with nets. In this nets lesson, students receive nets which they fold to make a three dimensional object. They predict what shape each net will make and verify it after making the net. They use the...
Curated OER
Faces of a Cube
Learners identify and correctly name three-dimensional solids; cones, spheres, and cubes. In this three-dimensional figures lesson, students build a cube by matching colored square faces to a correct word. Learners then...
Curated OER
Surface Area
In this geometry instructional activity, 10th graders define surface area, net and lateral face. They calculate the surface areas of cones, prisms and cubes. There are 9 surface area questions.
Curated OER
Polydron Fun
Students investigate nets as they relate to volume and area. In this geometry lesson, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects and...

Exploring Characteristics Needed to Prove Two Trianlges Congruent
Tenth graders explore congruent triangles. In this geometry lesson, 10th graders investigate the conditions necessary to prove two triangles congruent. The lesson combines dry erase board activities and the use of technology.
Curated OER
The Quirky Quadrilateral
Fourth graders identify and classify different triangles and quadrilaterals. Then they demonstrate an understanding of plane and solid geometric objects and use this knowledge to show relationships and solve specific problems. Students...
Curated OER
The Castle
Students build a castle to Ravi's design using the cubes. Students then make an original model of a solid object from diagrams which show views from the top, front, side and back. Students describe the reflection of rotational symmetry...
Curated OER
Volume of Spheres
Students find the volume of spheres. In this geometry lesson plan, students measure and derive the formula for each shape and solid. They use the correct terminology and units when solving these problems.
Curated OER
Polygon Sum Conjecture
Pupils calculate the sum of the angles of a polygon. In this geometry lesson, students use the interior angle formula of polygon based on the number of sides of the polygon. They identify the missing angle using algebra.
