This is a great lesson on how to measure and draw angles using a protractor. This is a mimio ink file. In this lesson, your students will learn about the four types of angles: acute, obtuse, right, and straight. They will also learn what perpendicular lines are. The lesson will teach students how to draw and measure angles using a protractor. This lesson is highly interactive and will have many students up and out of their seats at the board showcasing their work. I've also included a review game at the end of the lesson called Angle Tangle which will give the students practice estimating angles. Each slide has a set of directions that will explain how to each each slide to make it go smoothly.
