NSTA can help you reach science educators in every discipline and at every grade level through exhibit hall booths, workshops, program advertising, and more. Through NSTA, you’ll find leading resources for excellence in teaching and learning and experience growth through robust professional development. Each point or block that has been reflected must remain the same distance from the mirror line as the original point.
So if point A is 3 squares away from the mirror line, then the reflection of point A must also be 3 squares away. When reflecting a shape, look at the corners of the shape and reflect each corner first as a dot in the mirror line.
The basis and understanding of symmetry starts at about Grade 2, and then develops further in Grades 3,4 and 5.
All the free symmetry worksheets in this section follow the Elementary Math Benchmarks for Grade 3.
The sheets in this section are similar to those on this page, but are more complicated and at a harder level.
Looking for some geometry worksheets to get children thinking and reasoning about 2d shapes?

All the free second grade geometry sheets in this section support Elementary Math benchmarks. We welcome any comments about our site or worksheets on the Facebook comments box at the bottom of every page. The sheets in this section are similar to those on this page, but are less complicated and at an easier level. In geometry, student's learn about different geometrical shapes, their construction and questions related to calculation on them.
The line of symmetry is the imaginary line where we divide a figure into two halves that are the mirror images of each other. In addition to this, the letters D, E, H, I, K, M, O, T, U, V, W, X and Y are all symmetrical shapes. Plus you’ll meet colleagues across all science disciplines, all grade bands and teaching stages, from the newest teacher to the veteran administrator, who share a passion for science education. As a bonus, site members have access to a banner-ad-free version of the site, with print-friendly pages.Click here to learn more. There may be a line of symmetry in shapes irrespective of its being geometrical or non geometrical.The line of symmetry is a line segment that is drawn in between a diagram in order to make the diagram equally divided in two.

To complete this exercise your child will need to look at each shape, and then draw a line that will split the shape symmetrically in half.
The line of symmetry divides a picture into two parts so that one forms a mirror image of the other. Your child will gain experience drawing lines of symmetry with this worksheet, as well as recognizing shapes that are and are not symmetrical. In other words, the images on the other side of the line of symmetry, must be the reflection of each other. Line of symmetry may also be defined as the line segment along which when the image is folded one side over the other, the upper folded area fully covers the lower folded area. Line of symmetry may be a horizontal or a perpendicular line.The shapes that have a line of symmetry are known as "symmetrical", while those which do not possess any kind of line of symmetry, are termed as "asymmetrical". The line of symmetry is perpendicular to the horizontal plane that is called as a vertical line of symmetry.
