Grade 4 - Shape and Space

Standard 4.SS.6 - Determine the symmetry of a two dimensional shape in relation to an axis of symmetry.

Included Skills:

Demonstrate an understanding of line symmetry by:
• identifying symmetrical 2-D shapes.
• creating symmetrical 2-D shapes.
• drawing one or more lines of symmetry in a 2-D shape.
• Identify the characteristics of given symmetrical and non-symmetrical 2-D shapes.
• Sort a given set of 2-D shapes as symmetrical and non-symmetrical.
• Complete a symmetrical 2-D shape, given half the shape and its line of symmetry.
• Identify lines of symmetry of a given set of 2-D shapes, and explain why each shape is symmetrical.
• Determine whether or not a given 2-D shape is symmetrical by using an image reflector or by folding and superimposing.
• Create a symmetrical shape with and without manipulatives.
• Provide examples of symmetrical shapes found in the environment, and identify the line(s) of symmetry.
• Sort a given set of 2-D shapes as those that have no lines of symmetry, one line of symmetry or more than one line of symmetry.
