Students compare and contrast angles and identify them as acute, obtuse, right, or straight angles. They create rays and angles using uncooked spaghetti, read and discuss key vocabulary terms, and complete a variety of geometry worksheets.

Students classify angles. In this angles activity, students explore the characteristics of angles, triangles, quadrilaterals and circles. They identify polygons and sing a classifying angles song. Students participate in a...

High schoolers draw perpendicular bisectors.  In this perpendicular bisectors lesson, students identify the perpendicular bisector in a polygon.  They use web tools to create and measure perpendicular bisectors.  High...

In this line segments and angles instructional activity, students solve problem solving problems and multiple choice questions about line segments and angles. Students complete 7 pages of problems.

Students work to find and reinforce concepts related to lines and angles. They identify the characteristics of shapes that have one, two, and three dimensions. The students also work on definitions related to the geometry of shapes.

Students measure and calculate the angle of the sun. They compare the leaf types on the north and south to compare the effects of the sun on the type of vegetation. They complete the activities inside the classroom or on a trip to a...

Have your class review how to identify right angles. Learners identify right angles, and then write the number of angles found in each shape.

Students identify and determine angle pair relationships. In this geometry lesson, students identify different angles of parallel lines that are cut by transversals. They identify interior and exterior angles after watching a video.

How hard can it be to split something in half? Learners investigate how previously learned concepts from angle bisectors can be used to develop ways to construct perpendicular bisectors. The resource also covers constructing a...

Have scholars show what they know with a 20-page assessment aligned to the California State Standards. The test covers concepts such as large and whole numbers, all four mathematical operations, fractions, decimals, geometric figures,...

Providing both review and practice problems, this worksheet prompts students to answer five questions having to do with slope, tangents lines, graphing, the Squeeze Theorem, differentiable functions and derivatives. This activity could...

Students analyze a drawing of a regular octagon inscribed in a circle to determine angle measures, using knowledge of properties of regular polygons and the sums of angles in various polygons to help solve the problem. They use...

What figure is formed by connecting the midpoints of the sides of a quadrilateral? The geometry assessment task has class members work through the process of determining the figure inscribed in a quadrilateral. Pupils use geometric...

Review for the test with a comprehensive list of terms and concepts for the unit on congruence and similarity. It divides divides the sections in the order of the lessons presented during the unit. 

In this angle worksheet, learners match given terms to a picture that describes the term. Vertical angles, parallel lines, supplementary angles, adjacent angles, right angles are samples of the 20 listed terms. This one-page worksheet...

Sixth graders identify parallel and perpendicular lines in the alphabet. In this line properties lesson, 6th graders use the letters of the alphabet to show parallel and perpendicular lines. Students open a Geogrid Mat on the computer...

In this naming angles activity, 10th graders solve 12 different problems by responding to each statement defining the angles shown in each box. They name a linear pair in 3 of the problems and name a pair of supplementary angles in 4...

In this proving lines parallel activity, 10th graders solve 8 different problems related to proving that lines are parallel in each figure. First, students find the value of x so that line l and line m are parallel. Then, students...

In this circles learning exercise, students solve 10 multiple choice problems. Students answer questions about diameter and chord relationships, tangent lines to a circle, circumference, the Pi relationship, etc.

In this geometry worksheet, 4th graders complete a quick set of math activities where they first identify which portion of a model is shaded in fraction form. Then, they select which angle best describes a given angle. Finally, students...
