Eighth graders engage in a lesson that is concerned with the finding of angles that are found in different two dimensional figures. They compare and contrast exterior and interior angles while also determining the unknown measures of...

In this finding unknown angles learning exercise, 10th graders find each numbered angle's measure for 20 different angles shown in the diagrams. They calculate the size of an angle when the other two angles are known to equal 180...

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

Students work to find and reinforce concepts related to lines and angles. They identify the characteristics of shapes that have one, two, and three dimensions. The students also work on definitions related to the geometry of shapes.

Third graders search for and locate examples of acute, right, straight and obtuse angles in the classroom. They record their findings by writing the exact location of each angle found and organize them into angle categories.

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.

Although the title of Elizabeth Kann's story Pinkalicious isn't a real word, the book is an excellent way to explore some new vocabulary in context: acute, mushy, rare, steady, and surrounded. Find the...

Eighth graders label and define geometrical lines and angles. They identify angles on the board as acute, obtuse, straight, or right. In groups, 8th graders build with masking tape on the wall a pair of parallel lines, and a transverse...

Middle and high schoolers solve and complete 29 various types of problems. First, they match each name with its correct formula. Then, students find the length of the missing side and the distance between the two points given. In...

Pupils investigate triangles and their relationship to each other. In this geometry lesson, students solve right triangles using the properties of the Pythagorean Theorem. They differentiate between right, acute, straight and oblique...

After identifying angles (acute, obtuse, right) during a math or science lesson, 4th graders will use the computer to stamp pictures in the correct category using KidPix computer software.

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 perimeter activity, students find the perimeter of given triangles.  This two-page activity contains 6 problems.  Answers are provided on the last page.

Students explore how one artist portrays her own experiences and interests through her art. Students then choose themes in their own lives and create works of art inspired by those themes.

In this similar figure worksheet, learners find the length of a missing side of given triangles and quadrilaterals.  This six-page worksheet contains 24 problems.  Answers are provided on the last page.

Fifth graders use the SMART Board to demonstrate how to use a protractor to measure acute, obtuse, and right angles. In this protractor lesson plan, 5th graders also complete an angles worksheet.

Young scholars explore the relationship of angles as it relates to 2 and 3-D shapes. In this geometry lesson plan, students differentiate between acute, obtuse, right, alternate interior, exterior and adjacent angles. They...

In this angles worksheet, students analyze four angles. For each angle, students decide if it is greater, less than, or equal to a right angle. Students check the correct box.

 In this geometry instructional activity, learners read The Greedy Triangle and use geoboards to construct geometric shapes. They identify the number of sides and angles each shape has.

Fourth graders discuss and examine examples of the different types of angles. After learning the names of the geometric shapes students identify the types of angles and then complete the Kidspiration activity, Identifying Angles.

Students measure, construct, and classify angles as acute, right, straight, and obtuse. Once they have completed an angle worksheet, students use a map of South Carolina to locate cities by constructing the aforementioned angles.

In this geometry worksheet, 10th graders identify a triangle as right, acute, or obtuse and identify the parts of a right triangle in a drop and drag game format.  The one page interactive worksheet contains eight matching questions...

In this geometry worksheet, students match geometry words to illustrated examples. They find the missing angle of given polygons. This eight-page worksheet contains 45 problems. Answers are provided on the last two pages.

Students create different angles and shapes by using different lengths of straws. In this geometry straws lesson plan, students glue straws onto paper and define what they have made.
