4.G.A.1 (Geometry): Draw and identify points, lines, rays and right, acute and obtuse angles.
About this standard
Fourth graders draw and identify points, lines, rays, line segments and angles, and learn to name them with letters. Have your child point out these figures around the house, such as the edge of a table as a segment. Name each figure in Lines, Rays and Line Segments, then sort angles in Classify Angles: Acute, Right or Obtuse.
