In these angles and geometry worksheets, students learn about different kinds of angles, angle measurement, and other geometry facts. Students complete 15 questions.

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 create an original lesson about geometry and angles. In small groups they take pictures using a digital camera of obtuse, acute, right, and straight angles that they find at school. Students use the photos in a computer...

In this triangles worksheet, students draw different triangles and write how many sides and angles each one has. Students draw 4 kinds of triangles and have 2 that are impossible to draw.

In this angles worksheet, students measure and label angles as either acute, right, obtuse or straight. A reference web site is given for additional activities.

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

After reviewing characteristics of seven types of triangles, young geometers discover how to find the missing angle of a triangle. Then, they practice identifying triangles, find missing angles, and find missing side lengths of...

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!

In this math worksheet, students collaborate with a "study buddy" or "coach" to learn whether an angle is acute, obtuse or right. Students follow the directions to go through the process of deciding what classification an angle has....

This slide-show is packed with information relating to a variety of mathematical concepts. Intended as an accompaniment to a full unit, this resource provides definitions, explanations, and opportunities for learners to practice their...

In this angles worksheet, students identify a set of 4 given angles as either obtuse, acute, right or straight, checking the correct box next to each. A reference web site is given for additional activities.

Acute angles, nets, and vertices are only a few terms that a set of flash cards includes. Among the 108 cards, two types are available; word cards printed in bold-faced lettering, and corresponding definition cards equipped with an...

In this angle review instructional activity, students examine 4 angles and identify each of them as acute, right, obtuse, or straight angles.

In this sorting angles worksheet, students distinguish the differences between right, obtuse and acute angles. Students determine what type of angle thirteen angles are as shown.

In this measuring angles worksheet, students solve 10 problems in which angles are measured with a protractor and labeled with: acute, obtuse, right.

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

The interactive lesson plan featured here calls for the use of a Smartboard for sorting and classifying shapes. Then, pupils discuss the rules they followed for sorting their shapes, particularly focusing on the properties of angles....

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

Students explore symmetry.  In this geometry and scientific inquiry lesson, students design paper airplanes with middle line symmetry, as well as right, obtuse, and acute angles.  Students measure the plane's angles using a...

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...

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

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.

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

In this naming angles worksheet, students name each angle shown as an acute, obtuse or right angle, 12 angles total. Answers included on page 2.
