Basic Right Triangles
Elementary schoolers examine the attributes of triangles. In this triangle lesson, learners compare regular triangles and right triangles. They explore vertices and angles and investigate obtuse and acute angles. Pupils draw multiple...
Curated OER
Special Right Triangles
Students identify the different parts of a right triangle. In this geometry lesson, students use the Pythagorean Theorem to identify missing sides and angles of a right triangle. They work with irrational and rational roots.
Curated OER
Acute Triangles
Learners study acute triangles. They measure angles using a protractor, then classify the triangles as either right, obtuse, or acute. Everyone creates a design for a Navajo rug using only acute triangles.

Proof of the Pythagorean Theorem
What does similarity have to do with the Pythagorean Theorem? The activity steps through the proof of the Pythagorean Theorem by using similar triangles. Next, the teacher leads a discussion of the proof and follows it by an animated...
Curated OER
Animal Tracks
Students are introduced to the topic of area. In groups, they share various techniques to help them identify different shapes and work together to calculate the area. They use this same knowledge to determine the area of animal tracks...

The Pythagorean Theorem Lesson 2
Learners discuss and review examples of the Pythagorean Theorem using a GSP, Geometer's Sketchpad, activity.
Curated OER
Similar Situations
Students explore intersecting lines. In this intersecting lines lesson, students investigate shapes consisting of parallel, perpendicular, and similar lines. Students investigate these lines in shapes around them.
Curated OER
Ocean Friends Nametags
Students complete a number of activities to complete a study of ocean animals. They identify the animals, make nametags using appropriate colors, the animal habitats, and make a book by putting the pages in numerical order.
Curated OER
Parallel and Perpendicular Lines
Learners study parallel and perpendicular lines. In this parallel and perpendicular instructional activity, pupils explore 2-D shapes and determine if the sides are parallel or perpendicular.
Curated OER
Count the Animals
Primary graders count the number of pigs, horses, cows, elephants, and giraffes pictured (1-5). They write the numeral that represents how many of each are shown in boxes labeled with single examples of the animal. In addition to writing...

Parallel Lines Cut by a Transversal
Pupils study angle measurements between different types of angles associated with parallel lines and transversals. The independent practice asks pupils to identify the types of angles in a diagram and to determine the measure of angles.
Curated OER
Boyle's Law
Students create a piston/cylinder assembly using SolidWorks. In this technology lesson, students calculate volume, pressure and Boyle's law constant. They simulate equalizing air pressure by moving the piston out of the cylinder.
