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

Students identify and create angles. In this angle measurement lesson, students use sticks to make models of angles, then measure and name each angle.

Students draw a chart (included in the instructional activity) to use with their investigation. They review terminology of triangles and receive toothpicks to use in the instructional activity. Beginning with three toothpicks, students...

Students measure and label specified angles. In this angles lesson, students use a protractor to find angles that are acute, obtuse, and reflexive. Students then label each angle and match the angles the correct definition. This lesson...

In this triangle constructing and classifying worksheet, 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 on the "Check"...

Sixth graders estimate the measurement of angles and then measure the exact distance using an angle ruler. In groups, they explore shapes and recognize the characteristics acute, obtuse and right angles. Students sketch required shapes,...

Sixth graders investigate different types of angles. In this geometry instructional activity, 6th graders use a protractor to identify acute, obtuse, and straight angles.

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

Learners estimate angle measures in this this estimating angle measures lesson plan. 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...

With so many different types of triangles, it can be a challenge for young mathematicians to keep them all straight. Luckily this set of printable triangles is here to engage children in comparing and sorting triangles by their...

In this triangles worksheet, students draw angles with given measurements and identify each as either acute, right, obtuse or straight. A reference web site is given for additional activities. 

In this angles worksheet, students solve 4 problems in which an angle is analyzed and measured. Students tell if each angle is greater than, less than or equal to a right angle.

In this angles worksheet, students measure angles with a protractor and figure out if it is acute, right, obtuse, or straight. Students complete 6 problems.

In this polygons worksheet, students use the parallel, acute, right, obtuse, straight, and reflex to describe the five shapes provided.

In this triangles practice learning exercise, learners respond to 4 questions that require them to identify the pictured triangles as acute, right, or obtuse triangles.

Upper graders label four triangles and fill in the labels correctly. They draw three original triangles and answer the questions about them.

Here is a classifying triangles practice activity in which learners sharpen their problem solving skills as they solve six story problems.

In this angles worksheet, students identify a set of angles as either acute, right, obtuse or straight. A reference web site is given for additional activities.

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.

Learners 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.

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