Learners estimate angle measures in this this estimating angle measures lesson. They use an application on their graphing calculator that shows various settings involving angles and then they estimate the angle measure of a clock's...

Middle schoolers explore angle measure as they estimate angle measure and measure and draw angles of less than 360 degrees. The lesson emphasizes the use of estimation when measuring angles.

In this angles worksheet, students use a protractor and measure a set of 5 angles, checking the correct measurements and labeling as acute, right, obtuse or straight.

In this angles worksheet, students name and measure six angles.  Students then draw four angles with a protractor given the degree measure.

In this triangles activity, students measure and calculate the measurements of eight triangles, their sums and classify the triangles as acute, obtuse or right.

In this classifying triangles worksheet, 6th graders write the type of triangle, acute, right or obtuse, for 9 pictures of triangles, answers included.

This presentation shows how triangles are classified by angle measurement and length of sides.  It reviews isosceles, scalene, obtuse, right, and acute classifications and includes questions for students to classify some of the...

Students 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 practice the...

Students utilize their handheld and the Angles program to create a non-objective artwork. Images created by famous artists who have utilized angles in their art work are examined.
