Origami is an excellent way to combine Japanese culture, art, and geometric shapes into one engaging instructional activity! Scholars begin by listening to the story Sadako and the Thousand Paper Cranes and learn the origin of...

Here is a clever, cross-curricular lesson that combines art and geometry. Learners design a painting that uses geometrical shapes and is symmetrical. Sponge-shaped geometrical figures are used to design half a page and fold them to...

Potty humor is always a big hit with the school-age crowd, and potty algebra takes this topic to a whole new level. Here the class develops a model that connects the dimensions (radii, paper thickness, and length of paper) of a...

Construct tangent lines and make the connection to tangent functions. An informative lesson reviews the geometry origins of the tangent function. Pupils use that information to determine how to construct a tangent to a circle from a...

Second graders explore geometry by experimenting with fold-ables. In this geometric shapes lesson, 2nd graders utilize cutout shapes from construction paper which they experiment with by folding. Students examine the symmetry and...

Students investigate properties of circles. In this geometry lesson, students differentiate between similarity and congruence as they observe polygons. They investigate properties of two and three dimensional shape.

After walking in a nearby neighborhood, have your class create this amazing city street pop-up. They study the facades of the buildings they see, focusing on geometric line, shape, and architecture. They then draw, cut, and create a city...

Prove theorems through an analysis. Learners find the midpoint of each side of a triangle, draw the medians, and find the centroid. They then examine the location of the centroid on each median discovering there is a 1:2 relationship....

The University of New York Regents High School Exam for geometry from August 2009 is comprehensive in scope, with 38 questions over 22 pages. Geometers can assess their mastery of core content using a combination of multiple-choice and...

Make origami ducks with your class to reinforce geometry concepts and vocabulary; develop fine motor and visual translation skills; and enrich study of Japanese culture, the pond habitat, or migration. Create a whole group "worksheet"...

Time to learn about sundials. Scholars see how to build sundials after learning about Earth's rotation and its relation to time. The unit describes several different types of possible sundials, so choose the one that fits your needs — or...

Ninth graders experiment with paper folding to create geometrical shapes. Students analyze the Copymaster of the problem. After the students have worked on their own for a while, stop them and discuss.

Students graph and solve quadratic equations. In this functions lesson, students analyze a quadratic equation using three points on a curve to define the graph of a quadratic function. They find the vertex and intercepts of the graph.

Students predict the shape of a geometric figure in 3D. In this geometry lesson, students construct 3D shapes to perfect their knowledge of measuring and predicting. This assignment is also available as an online interactive lesson.

Second graders identify different polygons and their attributes. In this geometry lesson, 2nd graders get to know polygons by studying the vocabulary and finding polygons in their classroom. They create these shapes and then find their...

Triangle centers and the segments that create them easily become an exercise in memorization, without the help of engaging applications like this lesson. Here the class investigates the measure of center that is equidistant to the three...

Second graders make an origami Johnny Appleseed. In this geometry lesson students follow folding instructions. They find different geometric shapes while they are folding. They create Johnny Appleseed's body and attach a face and hands...

Students explore Fractal designs. In this geometry lesson, students observe the different polygons created in nature and relate it to math. They define polygons on planes and rotate polygons about a point.

In this geometry worksheet, high schoolers assess their knowledge of high school geometry. The 28-page worksheet contains a combination of 38 multiple-choice and constructed-response questions. Answers are provided.

In this geometry worksheet, 10th graders review geometric concepts such as angles, polygons, quadrilaterals, trigonometry, and circles. They take a comprehensive exam covering topics on the Regents exam. There are 32 pages in this booklet.

Seventh graders find the perimeter and area of triangles.  In this finding the perimeter and area of triangles lesson, 7th graders find the perimeter and area of triangles given two sides.  Students find the missing side by...

Eighth graders classify geometric figures.  In this polygon lesson, 8th graders identify given geometric figures.  They compare and contrast different polygons.  Students name line segments, identify parallel lines, and...

Students identify symmetry in shapes. In this geometry instructional activity, students fold paper to identify lines of symmetry. Students create various symmetrical shapes using folded paper.

In this Regents High School examination worksheet, students solve 38 geometry problems to prepare for the exam. Solutions are provided.
