Fifth graders explore geometric building blocks in the real world in order to describe the characteristics and relationships of points, lines, line segments, rays, and planes. This is the first lesson plan in a series of lessons in...

Tenth graders define terminologies related to geometry. In this geometry lesson, 10th graders discuss undefined terms, line segment and ray. They answer the question, how many points it takes to make a line.

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

In this exploring angles learning exercise, 10th graders solve 12 various types of problems that are related to measuring various angles. First, they name the vertex of an angle and determine whether it appears to be acute, obtuse,...

Fifth graders, after seeing Honeycomb examples, complete a Classifying Angles worksheet, Clock worksheet, and Defining Angles worksheet.

Tenth graders investigate parallel lines and the angles formed when cut by a transversal. In this geometry activity, 10th graders construct perpendicular lines and discuss midpoint, segments and perpendicular bisectors. They relate...

In this pre-calculus worksheet, students solve for angles formed by a tangent line and a circle. There are 6 different worksheets containing 8-10 problems per sheet.

Help 9th graders identify lines, points, rays, and planes in geometry. They  practice identifying, measuring, and drawing angles of different degrees. This is a fundamental lesson to help students learn the building blocks of geometry.

Students explore geometry by participating in a shape rotation experiment. In this symmetry lesson, students identify the term symmetry and a list of other geometry vocabulary. Students analyze shapes as they are turned 90 degrees and...

Students draw and measure angles. In this angle measurement lesson, the teacher demonstrates how to form and measure angles while explaining the parts of an angle, then students practice.

Eighth graders complete a unit of lessons on basic geometry concepts. They participate in a variety of activities, culminating in a project that involves publishing a booklet or a poster that presents the major geometry concepts from the...

Young scholars identify and use the computer keyboard to complete simple tasks. Students eliminate the use of the computer mouse to do simple jobs. They use keys that are used alone, keys that specify object labels, Keys that result in...

Students identify and use the similarity theorem. In this geometry instructional activity, students differentiate between congruent and similar triangles. They solve problems using the computer modifying shapes by dragging.

First graders create Aboriginal Dot Turtles using wax colors or crayons. The class discusses Aboriginal stories and art as a way to practice design. This lesson can be done in two 30-minute lesson segments.

High schoolers get together in groups to read and learn about the life of film actress Anne Bancroft. After a teacher-led presentation on her life, each of the groups must complete tasks described by the worksheets embedded in the plan....

Have you ever wondered how circles and angles relate to each other? Read a passage about right angles, acute angles, and obtuse angles, and answer reading comprehension questions about the information you learn. 

Need to go over some math concepts with your third graders? Use a series of math posters, featuring vocabulary words in geometry, measurement, fractions, probability, and many other areas of study. Each poster presents the term with an...

Scientists used flame tests to identify elements long before the invention of emission spectroscopy. Young chemists observe a flame test of five metal cations in the fourth lesson of an 11-part series. Individuals then work...

Learners observe and demonstrate a variety of basic geometric constructions using the Triman Safety Compass. Using the compass, they draw circles, bisect a line segment, construct an angle, bisect an angle, copy an angle, and create...

Learners explore angles and their use in Geometry. Students investigate three different kinds of angles: obtuse, acute, and right angles through an online activity. They identify pairs of angles with special relationships: vertical,...

Students create entries for the Architects of America contest, including a model of a futuristic structure, blueprints, a list of all plane and solid shapes in the structure, a persuasive argument paper that describes why the structure...

In this light learning exercise, students describe the electromagnetic spectrum based on wavelength and frequency. Students determine the wavelength, frequency, and energy for given point on the spectrum. This learning exercise has 10...

Geometric shapes are really cool. Examine triangles, quadrilaterals, trapezoids, rhombuses, parallelograms, pentagons, and hexagons with your class. They draw large shapes and small shapes then compare them to understand their shapely...

In this stars rise in the east worksheet, students use geometry to show how the Earth rotates from west to east and why celestial bodies appear to rise in the east and set in the west. Students draw a figure and label given points in...
