Quadrilateral Explorations-Grade Nine
Ninth graders investigate quadrilaterals. In this geometry lesson, 9th graders examine and classify quadrilaterals using the slope, midpoint and distance formulas. Additionally, students create various quadrilaterals given three point...
Curated OER
Corresponding Parts of Similar Triangles
Here is a lesson that has learners take a look at corresponding parts of similar triangles, ratios of similarity, reductions and enlargements. They'll manipulate the scale factor (r) to observe the changes in similar triangles and then...
Curated OER
Corresponding Parts of Congruent Triangles
Students identify different parts of a triangle. In this geometry lesson, students differentiate between similar and congruent triangles. They use the navigator to crate a visual of the different parts of a triangle.
Curated OER
Footprints
Students explore patterns. In this patterns geometry lesson, students identify and extend patterns including body parts, movement, geometric shapes, noises, and footprints. Students create and share an original pattern.
Curated OER
3D Shapes
In this geometry worksheet, 10th graders match vocabulary words with their definitions. They review words dealing with geometry and 3D shapes. There are 54 questions with an answer key.
Curated OER
Angles, Lines and Transversals
Students identify and determine angle pair relationships. In this geometry lesson, students identify different angles of parallel lines that are cut by transversals. They identify interior and exterior angles after watching a video.
Curated OER
Who Built That NYS Thruway Bridge Anyway?
Students discover how engineers determine the best designs for bridge construction. They see how bridge constructions relates Engineering to Geometry. They see the implications and consequences of bridge design on your community/world.
Curated OER
Creating Perpendicular Bisectors
Students create perpendicular bisectors. In this geometry lesson plan,students use a straight edge and protractor to create a perpendicular bisector. They graph line on the TI and analyze it.
Curated OER
Triangle Inequality Theorem
Students identify properties of triangles. For this geometry lesson, students create triangles using three different segments. They make conjectures and predictions.
Curated OER
The Search for Pythagoras' Treasure
Students identify and define properties of triangles. For this geometry lesson, students identify the missing sides and angles of right triangles. They use the rules of the Pythagorean Theorem to solve their problems.
Curated OER
Speaking Geometrically
Fourth graders are introduced to the vocabulary needed to identify the attributes of two and three-dimensional figures. They work together to create a word wall, which contains the geometric terminology being learned.
Curated OER
Faces of a Cube
Students identify and correctly name three-dimensional solids; cones, spheres, and cubes. In this three-dimensional figures lesson plan, students build a cube by matching colored square faces to a correct word. Students then explore...
Curated OER
3-D Figures Part 2
Students work with three dimensional objects. In this geometry lesson, students examine models of spheres, cones, cubes, prisms, and pyramids, and identify them by their edges, vertices, and faces.
Curated OER
Fold and Cut
Second graders explore line symmetry and the names and attributes of two-dimensional mathematical shapes. They study the context by folding and cutting out shapes to make a series of mathematical shapes.
Curated OER
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...
Curated OER
Quadrilateral Explorations
Ninth graders identify quadrilaterals and label the vertices of quadrilaterals. they justify their identification of the quadrilaterals. Students work in groups to identify and create quadrilaterals
Curated OER
Meet the Polygon Family
Fourth graders investigate regular polygons. In this regular polygon lesson, 4th graders explore the attributes of different polygons. Students work in groups to complete a KWL chart regarding polygons.
