Angles Lesson Plan Grade 6. Use arms to show an obtuse angle. Our triangles lesson plan for grades 4 6 prepares students to identify the four types of triangles and distinguish between each type.
Tell your students that perpendicular lines form a right angle. Students will learn to model the types of angles and apply this knowledge during an angles scavenger hunt and create an. Define an acute angle as one that is more than zero but less then 90 degrees.
Use arms to show an obtuse angle.
Tell your students that perpendicular lines form a right angle. They create visual representations of lines rays and angles by drawing them on paper and using a geoboard. Remind your students that a right angle is 90 degrees. Students are asked to draw each type of triangle and recognizing the types of triangles used for buildings and other structures and objects.
