Use the given tasks and detailed teacher's commentary to introduce your 8th graders to the Pythagorean theorem and its converse. Embedded links to information about Egyptian geometry make your presentation interesting. Consider...

Students create perpendicular bisectors. In this geometry instructional activity,students use a straight edge and protractor to create a perpendicular bisector. They graph line on the TI and analyze it.

Students use the human body as a foundation for gaining practice in measuring angles and calculating ratios and proportions.

Students investigate geometric relationship using conjecture about linear pairs and vertical angles. In this geometry lesson, students apply their theorems and previous geometry knowledge to solve for and find angles of linear...

By using circles that they cut out and label themselves, learners literally "get a grip" on the angles they identify: supplementary, complementary, and vertical. They solve missing measurements based on properties of supplementary,...

Learners explore the concept of triangle inequalities.  In this triangle inequality lesson, students cut spaghetti noodles into given lengths.  Learners use the noodles to complete a worksheet about triangle inequalities. ...

For this geometry worksheet, young mathematicians divide a parallelogram into four, by choosing points along a diagonal.  Students calculate the area of each parallelogram and look for any patterns that may emerge.  The...

Middle schoolers identify angles.  In this angles that pair lesson, students identify adjacent, vertical, complementary, and supplementary angles.  They use straws, pretzel sticks to demonstrate given types of angles. 

For this Aurora Borealis worksheet, students read about how early scientists used triangulation to measure the height of the Aurora Borealis. Students solve 3 problems using triangulation.

In this geometry worksheet, 10th graders identify the missing angles using the polygons sum conjecture. They measure exterior and interior angles using their angle theorems. There are 63 problems.

Students determine that two figures are similar or congruent by investigating figures that are similar and figures that are congruent. They prove that two figures are similar or congruent by using definitions, postulates, and theorems.

Students practice estiminating and measuring angles. After watching a short video, they identify angles in objects in the classroom and their homes. In groups, they participate in activities in which they are given a scenerio and are...

Students explore the concept of similarity and congruence. In this similarity and congruence instructional activity, students identify and verify whether or not two figures are similar, congruent, or neither. Students use postulates and...

Students explore the concept of similarity and congruence. In this similarity and congruence instructional activity, students cut out strips of paper and form a triangle. Students try to prove that their triangles are congruent using the...

Students use geometry or trigonometry to measure the distance of a far off point. They verify their measurements using a tape measure to check their work.

In these angles and geometry worksheets, students learn about different kinds of angles, angle measurement, and other geometry facts. Students complete 15 questions.

Students rewrite word problems and solve using math. In this word problem lesson, students gather data and observe the data. They relate this process to the scientific method and math. They review their data to be able to answer...

Fifth graders engage in a variety of hands-on and technology-rich activities involving the classification of quadrilaterals. They utilize protractors and rulers to investigate the characteristics of various types of quadrilaterals. They...

Collaborative groups work with geometry manipulatives to investigate conjectures about angles. They create a graphic organizer to use in summarizing relationships among angles in intersecting, perpendicular and parallel lines cut by a...

Students identify and create angles. In this angle measurement lesson, students use sticks to make models of angles, then measure and name each angle.

Sixth graders engage in problem solving, communicating, reasoning, and connecting to represent and solve problems, using geometric models.

Students investigate the relationship between perpendicular and parallel lines on a coordinate plane. For this geometry lesson, students differentiate lines based on their slopes.

In this algebra worksheet, 7th graders review and practice core concepts for their 7th grade exam. They review geometry, algebra and solving word problems. This assignments contains a booklet of worksheets.

Students construct two dimensional models to illustrate squared numbers. In this geometry instructional activity, students use graph paper and an x/y axis to build squares exponentially. Students identify powers and relationships between...
