Better Lesson: Finding Angles

Teach your class how to apply their knowledge of geometry as they explore the unknown. In order to find an unknown angle, students must understand that rectangles have four interior right angles, that right angles have 90 degrees, and...

Explore types of angles and the characteristics of each. After observing a PowerPoint Presentation, learners tour the school facilities and use a digital camera to capture prescribed angles. Using the digital pictures and written...

Junior geometers investigate the concepts of angles and turns using straws to perform a hands on activity. This is helpful for kinesthetic learners who have a hard time with mathematics. The lesson includes the dialogue to be used during...

How do you determine the size of an angle? Pupils learn about degrees and how to measure the size of an angle. The video associates the measurements to types of angles such as acute, obtuse, and right. The additive properties of angle...

Come full circle with a lesson on angles. A noteworthy video describes how to calculate the measures of missing angles in a diagram. It goes through several examples in which the sum of the angles is always a full circle, or 360 degrees.

Third graders are preparing to build bat houses. They have calculated surface area, identified nail placement, and will now collect data on angle types in this real-world activity.

Third graders decompose an irregular polygon into arrays to find the area.

This site provides six practice activities to learn how to partition a rectangle into rows and columns of same-size squares and count to find the total number of them.

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...

Third graders can solve real world problems using their understanding of multiplication and division and the relationship they share.
