Geometry Teacher Resources

Six resources make up the first unit in the Flipped-Mastery series for geometry. In the first lesson, scholars learn how to identify and name points, lines, and planes. They work with four postulates, then practice the skills for naming...

Imagine taking a complete geometry course remotely! Eleven units make up the My Geometry course. Each unit follows the Flipped-Mastery cycle of learning, divided into two semesters. Pupils watch and take notes on a video that details the...

The Exploring Space Through Math series offers six geometry lessons that use NASA resources to teach learners how to use the mathematics of deductive and spatial reasoning. They use geometry to compare the dimensions of the NBL pool, the...

The Geometry Unit 4: Triangle Congruence unit module contains five lessons—each with a video, teacher reference, practice packets, solutions, and corrective assignments. To begin, scholars review the types of triangles, then investigate...

Similar figures are the topic of Geometry Unit 6. Each of the four resources in the unit module contains a video, teacher reference, practice packets, solutions, and corrective assignments. In the first lesson, pupils learn the...

The point of this collection of 12 videos is to introduce learners to three basic parts of geometry—points, lines, and planes. The presenter provides definitions, shows how to classify shapes, provides examples, and shows how to use...

Young mathematicians use their knowledge of geometry and precalculus to study the movement of the robotic arm on the International Space Station (ISS) and the flight pattern of NASA’s C-9 jet. In addition, they use spherical coordinates...

The four lessons in the Geometry Unit 2 module are all about reasoning and proof. In the first lesson pupils watch a video introducing conditional statements and their related statements. Learners find out how to identify the hypothesis...

The Geometry Unit 3: Parallel and Perpendicular Lines Unit Module contains seven lessons, each with a video, teacher reference, practice packets and solutions, and corrective assignments. In the first lesson, pupils learn eight...

Six lessons comprise the Geometry Unit 7: Right Triangles unit module. In the first lesson, pupils review the Pythagorean Theorem and determine how to use the converse to determine whether a triangle is right, obtuse, or acute. Next,...

Four resources make up the Geometry 8 Unit Module. To begin, scholars review the different types of transformations. They work in more detail with translations by drawing the transformations and writing the algebraic rule. In the second...

Geometry Unit 10 contains six resources that cover surface area and volume. Scholars first watch a video explaining the basic terminology of three-dimensional figures, such as prisms, lateral edges, bases, and faces. They then learn how...

Six lessons make up the Geometry Unit 9: Area of Polygons unit module. Pupils review the formulas for finding the area of parallelograms and triangles. They apply previous learning of trigonometric ratios and the Pythagorean Theorem to...

The "Geometry Unit 12: Probability" series contains three video lessons designed for the flipped classroom. Learners watch as videos demonstrate several types of problems highlighting probability concepts, and then work through a series...

The five resources in the Geometry Unit 11: Circles Unit Module are designed for the flipped classroom. Pupils watch videos that show how to apply concepts about circles, tangents, congruent chords and arcs, and intercepting arcs....

Nineteen resources make up the Balanced Assessment: Advanced High School Math Packet designed to test learners' knowledge in Algebra II, Geometry, and Pre-Calculus classes. To demonstrate their understanding of concepts related to these...

One's knowledge of angles should measure up to expectations. Scholars watch a video to learn about angles in polygons. They first see how to partition a polygon into triangles to find the sum of the interior angle measures. They then...

Get help when teaching 3D shapes in Geometry by using these resources to introduce classification, practice labeling, and apply this knowledge to other types of problems.

This series of cross-curricular resources covers just about every subject, ranging from social studies to geometry to physical science. Each worksheet includes a reading passage and five questions that require learners to apply reading...

Are you looking for assessment tasks for Algebra 1, Algebra 2, or geometry? Check out this collection of 20 assessment tasks designed for high schoolers. Problems are presented with an open-ended format allowing students to use multiple...

Good assessments are hard to find—assessments that address content standards and fit into standard class periods. The six assessments in the middle school collection are 80-minute forms, divided into two 40-minute sections, and are...

A collection of six tests are designed to assess the College and Career Readiness of high school algebra I, algebra II, geometry, and statics and probability learners. Each assessment includes the test form and scoring and comes in 40,...

A precalculus playlist of 29-videos demonstrates the processes and includes step-by-step explanations of functions. The collection includes inverse trig functions, polar coordinates, graphing polar curves, parametric curves, analytic...
