Basic Geometry ... A Pathway to Angles
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.
Geometry is Fun and EverywhereGeometry, You Don’t Care? Geometry is Fun and Everywhere
Third graders investigate shapes in our world. In this geometry activity, 3rd graders describe plane and solid shapes and identify angles, solid objects and lines of symmetry. Students use online resources, graphic organizers and conduct research to gain a better understanding of this geometry unit.
The Building Blocks of Geometry
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 geometry.
Zoom-In: Exploring Geometry, Symmetry, and Congruency in the World Around Us (SMART Board)
Students view geometry in the world around them. In this geometry lesson plan, students look at buildings and find examples of symmetry and geometry. They look for 2D and 3D shapes and congruency.
Triangle Tango: Special Right Triangles
Students investigate properties of special right triangles. For this geometry lesson, students use the Pythagorean Theorem to solve for missing angles and sides. They perform reflections.
Sectors of Pizza
Students identify the properties of a circle. In this geometry lesson, students relate properties of diameter to sections of a pizza. They calculate the measure of an arc and missing angles.
Connecting Geometry Unit
Middle schoolers recognize the use of experimental and theoretical probability. They use area models as a way of comprehending the probability. Pupils talk about the differences between experimental and theoretical probability. Students use mathematical reasoning to find the theoretical probability of some events.
Tangrams and Geometry
Young scholars explore geometry related to real world situations and tangrams. They explore a math website, identify various shapes, draw and describe shapes, read about the history of tangrams, and create their own set of tangrams out of paper.
Garden Variety Geometry
A home improvement plan can help adult learners preparation for the GED exam. They review vocabulary, prepare diagrams, complete a worksheet, calculate perimeters and analyze how to approach a story problem. They identify many geometry concepts used in solving GED problems.
Geometry in the Real World
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 unit.
Grab Bag Geometry
Tenth graders analyze objects by name and sides. In this geometry lesson, 10th graders solve geometric equations using the sides and n-gons. They observe picture slides and draw conclusions.
The Fun Polygon
Junior geometers use hands-on manipulatives to explore and describe the properties and attributes of a fundamental polygon, the triangle. They learn different kinds of angles and their measurements. This well-written lesson plan provides five days of material, so you can pick and choose what would most meet your curriculum needs.
Students identify shapes and manipulate 2 and 3 dimensional objects. They view objects from different perspectives and review relative positions (near, far, between). They sing a shape song.
Geometry, Patchwork Quilts, and Native American Culture
Use geometric principles to analyze North American quilt patterns. Learners review the concept of area, perimeter, and symmetry. They explore the importance of the star in quilting and conduct research on Morning Star quilts using the Internet. This lesson would be great for an Open House or Math night!
Sixth Grade Geometry
In this geometry activity, 6th graders find the measurement of the angles in different shapes given. Students complete 15 problems.
Sixth Grade Geometry
In this geometry learning exercise, 6th graders find the measurement of the angles in many different shapes. Students complete 15 problems.
Taxicab Geometry-ID: 8643
Tenth graders explore non-Euclidean geometry. In this geometry lesson, 10th graders investigate “taxicab geometry.” Students investigate the taxicab distance formula and make comparisons between a circle in Euclidean geometry and a circle in taxicab geometry.
Geometry and Quilting
Students create a quilt square for a class quilt using at least three, two-dimensional geometric figures. They research and write a brief description of at least two different quilt patterns that they find. Pupils discuss that quilts are not only a part of America's heritage, and relate it to math and geometry. Students are introduced to a variety of geometric figures during a unit of geometry.
Complementary and Supplementary Angles: Geometry "Nspired"
Learners investigate complementary and supplementary angles. They use dynamic geometry (TI-nspire) software to manipulate rays to identify the conditions necessary to create complementary and supplementary angles. They find the measure of the missing angle given one angle in a pair.
What Is Hyperbolic Geometry?
Ninth graders discuss the concept of hyperbolic geometry. They complete Internet geometry activities and write essays comparing and contrasting hyperbolic geometry to Euclidean geometry.
