Triangle Teacher Resources

Introduce advanced math students to the power of trigonometry! The 14 lessons in the Module 4 collection are divided into three topics: Trigonometric Functions, Trigonometry and Triangles, and Inverse Trigonometric Functions. Each lesson...

The Geometry Module 2: Similarity, Proof, and Trigonometry collection includes 36 lessons that are divided into five topics: Scale Drawings, Dilations, Similarity and Dilations, Applying Similarity to Right Triangles, and Trigonometry....

Starting with right triangles (SOH-CAH-TOA) and working up to the concept of radians, this collection introduces students to trigonometric ratios and supports them in learning to evaluate trigonometric functions.

Twenty-seven lessons make up a math module designed for seventh graders to focus on the concept of geometry. Topics include angles, triangles, parallelograms, three-dimensional figures, and measurement using volume and area. Two...

Before diving into the formulas for area, show where the formulas connect to the shape of the figure. The four videos look at different shapes and by decomposing them, they end up relating directly to their area formula.

Just a simple collection of unit segments to use when teaching about slavery. This will also help fight against common misconceptions of slavery in the west.

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...

Check out the Common Core with a collection that represents all the 8th grade math standards. Most resources engage multiple standards but the main one is listed on the notes section of each tab. 

The 36 lessons in the Geometry Module 1 collection address transformations in teaching geometry brought on by Common Core. The focus here is on transformations and the relationships between transformations and congruence. Teacher...

Teach young mathematicians how to use coordinate geometry to program a robot that is bound in the room in which it sits . Help comes in the form of the 15 lessons in  the Module 4: Connecting Algebra and Geometry through Coordinates...

Scholars take part in 20 lessons covering math concepts—area, surface area, and volume. Learning opportunities enforce knowledge of measurement and geometric shapes. A mid-unit exam challenges pupils to demonstrate what they know this...

The concept of similarity is the focus of a module designed to boost eighth grader's math skills. Scholars examine the Fundamental Theorem of Similarity, dilations, and the Pythagorean Theorem. The module consists of 14 lessons and two...

You'll find fundamentals and advanced activities focused on the Pythagorean Theorem in this collection, which was designed for high schoolers but helpful for young geometrists of all ages!

Need some help aligning your 6th grade math curriculum to Common Core? Here is a collection complete with a resource for every standard in the curriculum. While many of these resources cover multiple math standards, the main one...

All Algebra, all the time! Here is a compiled list of resources that address all of the standards regarding Algebra Common Core for high school. Each resource has the main standard it addresses under the notes section of the item. 

A collection of different resources can augment any math curriculum. Sheets can be printed, posted on the wall, or emailed to students for use in the classroom.

Eighth graders delve deep into the concept of congruence with a 16-lesson math module. Lessons plans offer guided practice, inquiry-based learning opportunities, and independent practice. A mid-module assessment gauges progress while an...

A math module challenges young mathematicians to generate equivalent expressions.  Scholars demonstrate how order or grouping does not affect the practice of addition and multiplication. By the end of the module, learners recognize and...

Small but mighty, a collection of three resources features presentation slides that prepare high schoolers for the Smarter Balanced assessment. Claim 2 features problem solving questions drawn from all content areas. Claim 3 focuses on...

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...

Building on the understanding of congruence studied in Module 1 and on similarity studied in Module 2, the 14 lessons  in the Module 3 collection focus on developing a bridge  from geometric measurement in two dimensions to understanding...
