We began with some VERY quick notes about angles today. I know my students understand right angles (90 degrees), acute angles
I gave the students an activity from the AIMS Education Foundation called "Flight Paths." Basically, students use a ruler to connect three cities and form an angle. Once the angle was formed, I demonstrated using an index card to determine whether the angle was acute, obtuse, or a right angle. You can watch this demonstration on my video: Angles.
I did not ask the students to find the exact measurement of each angle, this is not a 5th grade TEK. Instead, I asked them to label the angle <90 degrees, >90 degrees, or 90 degrees.
The kids really enjoyed this activity! There was not a moment off task! The most challenging part of the activity was finding the cities on the map. I like when they can see how math intermingles with other content areas!
