Students observe and demonstrate a variety of basic geometric constructions using the Triman Safety Compass. Using the compass, they draw circles, bisect a line segment, construct an angle, bisect an angle, copy an angle, and create...

How can we identify shapes in the Universe? High schoolers will compare and contrast elliptic and hyperbolic geometry. They will also explore one possible way to measure the curvature of the Universe, namely, by measuring the sum of the...

In this geometry worksheet, students define important vocabulary dealing with circles. They measure cricles to the nearest degree. There are 11 word problems to be solved.

Examine the process of rotating images to visualize effects of changes to them. The fifth lesson plan of 18 prompts pupils to rotate different images to various degrees of rotation. It pays special attention to rotations in multiples of...

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...

Students receive a copy of a "Spaghetti Measure" task sheet along with the scoring rubric. Students preview the task and the rubric prior to starting the task. tudeThey determine the circumference of a circle of spaghetti that will...

Students are introduced to some basic concepts of geometry. They explain that the definition of a triangle is a figure with three sides, three angles, and three points. Triangles can be named by using three points in their correct sequence.

Learners use the axes and measure angle tool to explore and calculate complementary angles with Cabri Jr. They also identify what happens to the calculation as they drag the endpoint into a different quadrant. Finally, they label each...

For this Sun and Moon worksheet, students solve 6 problems about the angular scale of the images given, the size of the features on the images and the area of the features shown.

Students experiment and analyze triangulation to assess degrees of combined angles, predict polygons that tessellate as well as extending of shapes to create tessellations. They explore the concept of why some polygons tessellate when...

Learners examine how to investigate polygons using an instrument of their own construction. They should be able to prove the general formula for the number of degrees in any polygon (including a triangle). Finally they investigate an...

Students practice measuring using the metric system and millimeters. They measure their thumbs and record their findings. Students record the findings of their classmates and find the average or mean for the two groups.

In this quadrilaterals worksheet, 10th graders solve and complete 10 different problems that include identifying various quadrilaterals. First, they indicate whether the statements are true or false for each. Then, students determine the...

Young scholars work with thermometers to complete problems about temperature. They investigate cooling patterns, how location affects temperature, and what happens when water having different temperature is mixed. They measure...

In this rotational symmetry activity, 5th graders determine if the two figures have rotational symmetry. This activity explains and provides examples of rotational symmetry.

In this online interactive math skills worksheet, students solve 10 multiple choice math problems regarding geometry skills. Students may view the correct answers.

Guide your geometers through the process of constructing polygons. They learn how to draw triangles, squares, parallelograms, rectangles, rhombuses, and trapezoids with specified angles using a protractor and a ruler. The lesson plan...

In this geometry worksheet, students read a scenario and translate it using geometric concepts to find their answers. There are 15 questions with an answer key.

Students utilize triangulation techniques to determine altitudes of objects. An altitude locator is constructed and used to determine the height of a building or a tree. Tangent tables and formulas provide the ratio for the formula to...

Fifth graders view prints of M.C. Escher's work. They look at examples of geometric figures and polygons and discuss places they have seen them. Students create their own tessellations. They write a report about the process they used in...

This unit covers the basic trigonometry including understanding radians, how to convert between radians and degrees, the area of a circle subtended by an angle, basic properties and graphs of sine, cosine, tangent, and solving...

Learners participate in finding the slope of a sand pile and then other materials. In this geology lesson, students describe what happens to the piles of materials when they are poured through a funnel. Learners measure the slope using a...

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.

In this geometry worksheet, 10th graders solve for missing sides and angles of a triangle. They use the pythagorean theorem to solve for the unknown in a right triangle. There are 5 questions on this worksheet.
