Students create three-dimension models demonstrating exponents, multiplying and dividing of fractions, and the use of repeating patterns in tessellations, mirror images, and tiling.

Students compare and contrast angles and identify them as acute, obtuse, right, or straight angles. They create rays and angles using uncooked spaghetti, read and discuss key vocabulary terms, and complete a variety of geometry worksheets.

Seventh graders recognize the characteristics of isosceles triangles. In this isosceles triangle activity, 7th graders use geoboards to create isosceles triangles. Students record results and explain why they have an isosceles triangle.

Students study bone size, structure and shape. They use various geometrical shapes to make a skeleton and produce a poster depicting the skeletal system and its functions. They arrange the pictures into the five sections, glue on...

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...

In this area activity, students complete a ten question multiple choice test by finding the area of various geometric figures. This is an interactive activity.

Second graders utilize manipulatives (pentominoes) to demonstrate knowledge of: lines of symmetry, slides, reflections (flips), rotations (turns), area, and perimeter. This instructional activity gives students a meaningful way to...

Students, in groups, determine the volume of a box large enough to hold a million dollars. They calculate the dimensions of a bill and the volume of the money.

Students learn and review basic geometric terms, definitions, and theory, including regular polygons, lines, angles, points, etc. They make a tessellating stamp and create a repeating work of art.

In this congruency worksheet, students find congruency in everyday packaging on everyday items and answer questions about them. Students answer 4 questions.

Learners calculate the area of a parallelogram. For this geometry lesson, students perform translation using a coordinate plane and coordinate pairs. They perform translation on other polygons.

Students calculate the area of parallelograms. In this geometry lesson, students identify properties of parallelograms and use to to solve problems. They create polygons using Cabri software.

Students identify three-dimensional forms in various buildings and construct three-dimensional paper forms.

Students find the median of trapezoids and other polygons. For this geometry lesson, students identify important properties of trapezoids. They create trapezoids and polygons using Cabri software.

Learners investigate and solve Pythagorean triples. In this geometry lesson, students find the missing sides and angles of a right triangle. They graph right triangles and move the sides around to create different angles.

Young scholars investigate the Pythagorean triples. In this geometry lesson, students solve for different parts of a right triangle. They identify the missing side or angle using the pythagorean theorem.

Students identify missing sides and angles. In this geometry lesson, students use triangular theorems to identify the missing sides. They use the Pythagorean Theorem to find the different ratios of each side.

High schoolers calculate the volume of the Pantheon's columns and estimate changes in weight given different parameters.

Students solve problems using geometric means. In this geometry lesson, students create altitudes in right triangles. They use Cabri software to move the triangle around and observe different sides and angles.

First graders learn how use a ruler to measure common items. For this measurement lesson, 1st graders examine the numerical markings on rulers and learn that each number stands for a unit of measure. They measure 5 classroom items after...

Learners calculate the inscribed angle of a triangle. In this geometry lesson plan, students identify the angle created by intersection of a triangle and a circle. They see the relationship between the arc and the angle.

Students use the secant and secant segment theorem to solve problems. In this calculus lesson, students identify where the secant line crosses on a circle. They create circles and secants using cabri software.

Second graders locate, comprehend, interpret, evaluate, maintain, and apply information, concepts, and ideas found in literature, the arts, symbols, recordings, video and other graphic displays, and computer files in order to perform...

Students identify the properties of solids and polygons. In this geometry lesson, students identify the different measurements of a triangle. They use congruence parts and theorem to prove their answer.
