They say a picture is worth a thousand words—and your pupils may agree after this instructional activity! They read a geometric description and create a diagram from that description. Their diagrams help them find unknown measures based...

Viewers learn how to apply proportional reasoning to find area of sectors and arc lengths with a video that starts off explaining how to find the areas of circle sectors and the lengths of arcs. Scholars then practice solving problems...

Use this during the season of teaching about the seasons! As Earth revolves around the sun, its tilt causes the weather to change. The graphics in this presentation show how Earth's position in space has an effect on the angle of...

Without water there would be no life on this planet. Biology learners find out why by reading this handout. Create a worksheet of questions to answer after the reading. Follow it up with quick demonstrations or laboratory activities that...

Identifying types of angles meets real-world application in an excellent, hands-on geometry activity. Learners use pipe cleaners and a visual model to independently discover the acute, right, or obtuse angles in their classroom,...

For this angle measurement worksheet, 10th graders solve and complete 9 different word problems. First, they read the word problems carefully. Then, students draw a picture that represents each problem and solve. Finally, they find side...

Students create angles using mirrors. In this angle reflection lesson, students draw angles, then use mirrors to create angles using reflections and measure the new angles.

Fourth and fifth graders write the measurement of the missing angle in six problems include three triangles, a semi-circle, and two circles. They use a protractor and the given angle measurements to draw six angles.

Learners identify obtuse and acute angles in comparsion to a right angle. They identify obtuse, acute, and right angles. Pupils use "Shape Measure" to construct obtuse, acute, and right angles. They review line segements to locate right...

Get out those protractors! Once geometers can identify obtuse, acute, right, and straight angles, get them to measure and draw their own. There are six boxes here, each with an angle measurement. Learners use a protractor to draw the...

Is it a line, line segment, ray, or angle? Identifying geometric figures is the focus. In addition to identification, learners recognize right angles or tell if an angle is less than or greater than a right angle. They tell if lines are...

A very cute presentation on the four types of angles can be found in this resource. Young mathematicians are introduced to obtuse, acute, right, and reflex angles. Charming stick figures are depicted using the angles. Great for use in...

Students identify and label acute, obtuse, and right angles within a picture. Using Kid Pix software and digital photos, they manipulate, identify, and label the angles and describe the angles to a classmate.

In this missing angle measures learning exercise, students subtract the angle that is given from 180' to find the missing angle measure. Students complete 6 problems.

Here is a well-designed presentation on different types of angles for your young geometers. In it, learners view slides that clearly illustrate what these angles are, and how they are formed. Excellent practice when introducing these...

Upper graders solve ten multiple choice problems about angles and measuring angles.

Take a look at these angles: What kind are they? Give mathematicians practice identifying obtuse, acute, and right angles in this categorizing activity. Each type is pictured and explained at the top, and scholars examine nine sample...

An interactive assignment displays two example angles to teach how to measure them. When you click on the angles, a protractor appears! As practice, learners view a set of angles, estimate the size of each, and then enter the degrees in...

Practice recognizing types of additive angles with a instructional activity in which pupils review adjacent, interior and exterior, complementary, and supplementary angles and use a diagram to give examples of them. Be aware that the...

Explore with your class the characteristics of acute, obtuse, right, complementary, and supplementary angles. They take digital photographs around the school and identify the angles in the images. Uisng software, they label and...

Geometers identify and determine angle pair relationships when two parallel lines are intersected by a transversal. They review the concepts of angles by watching streaming video clips online, read definitions of lines and angles from...

Learners address 14 questions that include naming all pairs of opposite and supplementary angles for sets of intersecting lines and then, finding the measure of the unknown angle. They determine the measure of the angle that is...

Fourth and fifth graders make a protractor and identify various angle types. In this protractor and angle lesson plan, learners make their own protractor and use it to measure a variety of angles. They complete worksheets while...

Get out those protractors! From any angle, this activity will give your mathematicians some good practice. First, they find the measurement of eight angles. Next, they draw eight angles given the measurement.
