Grade 3 - Geometry and Spatial Sense

Standard 3.GSS.3 - Determine the symmetry of a two dimensional shape in relation to an axis of symmetry.

Included Skills:

Location and Movement
• describe movement from one location to another using a grid map (e.g., to get from the swings to the sandbox, move three squares to the right and two squares down);
• identify flips, slides, and turns, through investigation using concrete materials and physical motion, and name flips, slides, and turns as reflections, translations, and rotations (e.g., a slide to the right is a translation; a turn is a rotation);
• complete and describe designs and pictures of images that have a vertical, horizontal, or diagonal line of symmetry (Sample problem: Draw the missing portion of the given butterfly on grid paper).
