Estimating Angles with Skitch

CCSS.Math.Content.4.G.A.1
Draw points, lines, line segments, rays, angles (right, acute, obtuse),
and perpendicular and parallel lines. Identify these in two-dimensional
figures.

Step One Create a Model of Angles:

  • Have students start a presentation in a whiteboard app.
  • Have students draw models of angles.

Step Two: Find Angles in Real Life.

  • Using the camera walk around classroom and take pictures of angles
  • Then have students use skitch to draw on the angles and make their estimation.
