Pythagorean Theorem Teacher Resources

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,...

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...

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...

Ten resources make up a collection of student and teacher-friendly slides that prepare eighth graders for the Smarter Balance assessment. Learners review rational and irrational numbers, convert repeating decimals to fractions, as well...

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...

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,...

Prepare eighth graders for high school math and science classes with a collection of 10 lessons that help tweens make the transition from acquiring basic knowledge to applying it in more complex situations. These Common Core-aligned...

Prepare eighth-graders for the Smarter Balanced Assessment with a small but powerful collection of three resources comprised of teacher and student-friendly slides that review key concepts in the eighth grade standards. Claim 2 focuses...

Special relativity is a physical theory that explains the relationship between space and time. A collection of eight videos makes this complex—and at times confusing—concept a little easier to understand. Simple drawings illustrate each...

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...

The three lessons in the Algebra II series Exploring Space Through Math expand learners’ knowledge of algebraic thinking and symbolic reasoning and encourage them to connect algebra and geometry. Activities include calculating the number...

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...

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...

Seventeen short assessments are designed to test scholars’ knowledge of basic Algebra 1 concepts. Pupils determine the houses that are a given maximum distance from a school, complete charts to show equivalent scale factors, and...

The Exemplar High School Balanced Packet is a collection of 19 assessment tasks designed to test scholars’ knowledge of Algebra 1 concepts. Learners create graphs that represent how things change over time, build functions to model...

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....
