Identify Cones
Third graders evaluate the attributes of cones. In this space shapes lesson, 3rd graders analyze three-dimensional shapes. Students explore the faces and edges of a cone.
Curated OER
Opening A Cube
Fifth graders investigate mathematical concepts related to the construction of a three dimensional cube. They construct the cube from two dimensional patterns and compute the surface area. Students also define the faces, edges, and...
Curated OER
Connecting With Coordinates
Play a coordinates game to encourage collaborative learning and grid use! Learners plot points on grids and play a game that challenges them to locate a specific point on a coordinate grid by using horizontal and vertical movements.
Curated OER
Three Dimensional Sketching
Students become familiar with drawing segments and points. They understand how perspective drawing differs from three dimensional sketching. They demonstrate three dimensional and perspective drawing.
Curated OER
Geometry Institute Lesson
Students practice geometry skills. In this geometry lesson plan, students find the surface area of cubes and prisms, identify shapes on solids, and distinguish between 2-dimensional objects and solids.
Curated OER
Area Applet
Elementary math classes calculate the area of a shape and explain the correlation between the size of the perimeter and the areas that can be contained within that perimeter. They also explain the effect the shape of the perimeter has on...
Curated OER
Perimeter and Area of 2D Shapes
Students find the perimeter and area of circles, triangles, and rectangles. In this perimeter and area lesson, the teacher gives students formulas for each shape and measurement and works through examples on the board. While no creative...

Awesome Area - Geometry and Measurement
Break out those math manipulatives, it's time to teach about area! Capturing the engagement of young mathematicians, this three-lesson series supports children with learning how to measure the area of squares, rectangles, and other...
Curated OER
Analyzing 3-D Shapes and 2-D Representations
Students can analyze 3-D objects better with actual physical models and by also drawing 2-D representations of them.
Curated OER
Paper Maché Mancala Game Boards
Seventh graders create three dimensional works of art from two dimensional plans, develop skills in papier-mach?? technique, utilize elements and principles of design to create 3-D form, and develop math/strategy skills in playing the...
Concord Consortium
The Six Faces of Amzora
Here's a task that is out of this world! Given a description of a fictional cube-shaped planet, scholars answer a set of questions about the planet. They create a two-dimensional map and consider the distances between locations on the map.
Curated OER
Creating 3-D Shapes in Art
By learning techniques for drawing 3-D shapes, students can create realistic drawings.
Curated OER
Geometry is Fun and EverywhereGeometry, You Don’t Care? Geometry is Fun and Everywhere
Third graders investigate shapes in our world. In this geometry lesson, 3rd graders describe plane and solid shapes and identify angles, solid objects and lines of symmetry. Students use online resources, graphic organizers and conduct...
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.
Curated OER
Shape City
Students add to a class Shape City by designing and constructing new buildings.
