Fifth graders practice measuring angles by using protractors.

Young scholars explore the concept of angles by interacting with numerous types of measurements. They create index cards with different angles. Then they pass the cards around to other students for comparison and measurement. They...

In this measuring angles worksheet, students use protractors to measure 9 angles and classify them as obtuse, straight, acute or right angles.

In this angles learning exercise, students measure and classify angles with a protractor. Students complete the measurement of 9 angles.

In this angles worksheet, learners measure the angles in the protractors on the worksheet. Students complete 6 problems total on this worksheet.

Logical thinking is at the forefront of this jam-packed lesson, with young mathematicians not only investigating geometric concepts but also how they "know what they know". Through each activity and worksheet, learners wrestle with...

Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...

Can you prove it? Making assumptions in geometry is commonplace. This resource requires mathematicians to prove the parallel line postulate through constructions. Learners construct parallel lines with a 180-degree rotation and then...

Investigate dilations to learn more about them. The second segment in a series of 16 provides a discussion of properties of dilations by going through examples. The problem set provides opportunities for scholars to construct dilations.

Watch the excitement grow as learners experiment with homemade rockets. Pupils create their own rockets from a soda bottle and experiment with launch angles. They discover the launch angle has a significant effect on the distance the...

One of the basic properties of inscribed angles gets a triangle proof treatment in a short but detailed exercise. Leading directions take the learner through identifying characteristics of a circle and how they relate to angles and...

Searching for a detailed lesson plan to assist in describing rotations while keeping the class attentive? Individuals manipulate rotations in this application-based lesson plan depending on each parameter. They construct models depending...

Construct an understanding of triangle congruence through a visual analysis. Young scholars find that given two sides and a non-included angle, sometimes two possible triangles are produced. Their analysis shows that if the non-included...

In this triangle constructing and classifying instructional activity, students read through a tutorial on triangles and angles. Then, students complete 17 exercises in which they answer questions about angles and triangles. By clicking...

Students follow the directions on the attached worksheet to construct shapes using Geometer's Sketchpad. To start the lesson, it is suggested that the teacher guide the students through the initial problem. When constructions are...

In this angle constructions worksheet, 6th graders solve and complete 4 various types of problems. First, they construct a perpendicular bisector of two points. Then, students construct an angle bisector for the angle shown. In addition,...

In this constructions and loci worksheet, students create a scale drawing of a running track. They identify the starting positions for a given race. Students bisect angles. They construct an angle trisector. This three page worksheet...

Sixth graders explore lines and angles. They create visual representations of lines, rays and angles by drawing them on paper and using a geoboard. On paper, 6th graders write a summary of the characteristics of their representations.

Fifth graders create and classify straight, right, acute and obtuse angles. In this clever lesson, 5th graders utilize pretzel sticks to form different types of angles. Best of all, they get to eat them at the end!

Young scholars measure angles.  In this angle lesson, students draw angles.  They  use a protractor to measure angles and identify the angle as straight, right, acute, or obtuse. 

Fifth graders explore the three types of angles. In this math lesson, 5th graders estimate the measure of angles and draw the angles using a protractor.

Students observe and solve examples of corresponding angle postulates, alternate interior angle theorems, and exterior and consecutive angles. They complete the Determining Angle Measure With Parallel Lines worksheet.

Students investigate points and angle bisectors. In this geometry lesson, students define angles, bisectors and perpendicular bisectors. They analyze angles and bisectors using Cabri software.

Middle schoolers calculate angle measure for triangles and complementary/supplementary angles. After a lecture/demo, students utilize a worksheet imbedded in this plan to gain practice.
