Students investigate geometric shapes by creating figures on a plane. In this polygon lesson, students complete a worksheet based on the angles in a power polygon. Students identify the different types of polygons and define their...

In this slope angles learning exercise, students discover the relationship between slope and angle.  Students complete tables of values and answer four discussion questions.

Pupils investigate why the North Star was important for navigation, how stars move across the night sky, how to locate the North Star, how to make a crude sextant, and how to determine latitude using a sextant and the North Star. They...

Fifth graders explore angles by using protractors. They recognize, describe and determine the surface area and volume of three-dimensional shapes. Students recognize the right angle, acute angle, obtuse angle and vertex. They identify...

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...

In this shapes and designs worksheet, 10th graders solve and complete 6 different types of problems. First, they fill in the first two columns of the table show with their shapes. Then, students measure the interior angles of each...

In this geometry worksheet, students use a ruler and a protractor to measure the lengths of the line segments and size of the angles that make up a drawing of a Christmas tree.  The one page worksheet has one problem.  Answers...

Students place a pencil perpendicular to the ground and trace its shadow between 11:30 AM and 12:30 PM. They measure the length of the shadow, periodically over several hours, in either English or Metric units. Using the data, they find...

How many different types of triangles can your class name? A discovery lesson guides learners through an exploration of the different triangle types and the relationships between their angles and sides. Using coordinate geometry,...

Young scientists study light reflection and refraction as they determine the critical angle, the rainbow angle, and color separation in rainbows. Teams record the data they collect in a shared spreadsheet and discuss results with the class.

Address key vocabulary in the seventh grade Common Core Math Standards with this comprehensive list. A series of word cards is also provided that supports each term with images and examples, making this an excellent tool for teaching the...

Young mathematicians practice measuring acurately with a protractor. They convert measurements using a scale factor, then translate the new information into diagrams. This instructional activity should be a hit in that it's mostly...

Eighth graders use a meter stick that is placed on a horizontal surface and an object is moved along it so that the shadow length can be measured at different distances from the light source. They solve real-world problems involving...

In this angle worksheet, students complete a set of 10 multiple choice questions. An answer link is provided; page is labeled as a "post test."

Students examine the correlation between art and math. Using their computers, students construct and measure angles. Students identify the properties of angles and polygons. They engage in the Angles program on their Palm and use the...

Students examine a sample budget and categorize the entries as a group. Then in small groups they convert budget category totals to percents and degrees to make a circle graph related to a sample budget.

Middle schoolers estimate and accurately measure the size of angles communicate with the appropriate geometric terms and symbols to describe and name angles, lines, line segments, rays

In this math worksheet, students measure the different angles for the six problems. They use a protractor and also estimate the solutions.

Students construct parallel lines using a protractor and a straightedge. In this geometry lesson, students identify the properties of parallel lines. They use Cabri to graph and observe the lines.

What's similar about congruent and similar polygons? Young mathematicians first measure the side lengths and angles of given figures. They use these measurements to determine relationships between side lengths and angles of congruent and...

Parallelograms are pairs of triangles all the way around. Pupils measure to determine the area and perimeter of a parallelogram. They then find the area of the tirangles formed by drawing a diagonal of the parallelogram and compare their...

Enough stuffed crust to go around. Pupils calculate the area and perimeter of a variety of pizza shapes, including rectangular and circular. Individuals design rectangular pizzas with a given area to maximize the amount of crust and do...

Eighth graders create rockets that be launched at varying angles to determine which angle is best to launch at for the longest distance.

Students make a circle graph. In this graphing instructional activity, the teacher conducts a class survey, then demonstrates how to make a pie graph. When students are comfortable with the material, they use a worksheet to create their...
