Basic Geometry Terms
Set your pupils up to start on geometry by teaching them some introductory terminology. Pupils learn the terms by reading a short passage and looking at examples. They then respond to five questions related to the text.

Create, Classify, and Sort Quadrilaterals
Quadrilaterals can be quirky! Fourth graders use geoboards and bands to create four-sided figures. They analyze the attributes such as angle size and presence of parallel sides. As a result they learn to differentiate among...

Area of Common Geometric Figures
Scholars can use area formulas, but can they apply what they know about area? The lesson challenges learners to think logically while practicing finding area of shapes such as rectangles, circles, parallelograms, triangles, and other...

Algebra/Geometry Institute Summer 2007 - Perimeter of Polygons
Sixth graders find the perimeters of polygons and use perimeters to form polygons. In this perimeter lesson, 6th graders study vocabulary associated with finding perimeter such as polygon, line segment, variable, and formula. They make...
Curated OER
Geometry
In this geometry/math learning exercise, learners name eight shapes by circling the name that best describes it. Students select the correct answer from 4 choices.
Curated OER
Geometry
In this geometry worksheet, students identify the different shapes created by nets. They also identify the intersection of lines and planes. There are 5 questions with an answer key.
Curated OER
Make a Box
Learners use specific dimensions to create a box. In this geometry instructional activity, students analyze the different properties of two and three dimensional shapes. They make conjectures and use it to solve problems.
Curated OER
Geometry: Congruent Figures
In this congruent activity, students identify congruent figures in a given set of shapes. A reference website for additional resources is given.
Curated OER
Faces, Vertices, Edges
Students identify the parts of three dimensional objects. In this geometry lesson, students find the number of faces, edges and vertices. They differentiate between prisms and polyhedra.
