Meet Morisu in the dojo. Help him with symmetrical objects and shapes!

Practice identifying lines of symmetry on shapes. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

[Free Registration/Login may be required to access all resource tools.] This concept teaches students how to determine whether or not a shape has reflection symmetry and how to draw lines of symmetry.

Visit this African village and learn about symmetry and parts of 2D shapes. Users can first watch a video that helps with the concepts of finding a vertex and a line of symmetry. They can then practice their knowledge on four activities...

Students will play interactive games and explore symmetry.

[Free Registration/Login may be required to access all resource tools.] In this learning module, students are asked to state whether the given 2D shapes have line symmetry. Includes video demonstrating a sample problem [1:14] and a set...

[Free Registration/Login may be required to access all resource tools.] In this learning module, students are asked to state how many more squares on a grid need to be shaded in order to give a shape line symmetry. Includes video...

[Free Registration/Login may be required to access all resource tools.] Students watch a video and take an assessment on identifying and counting lines of symmetry in various shapes.

In this lesson, 3rd graders first examine images and decide whether they are symmetrical or not. Next, they create individual symmetrical shapes with their bodies and identify the line of symmetry present during these shapes. They then...

[Free Registration/Login may be required to access all resource tools.] In this learning module, students are asked to identify where a line of symmetry should be and whether a 2D shape has a line of symmetry. Includes video...

[Free Registration/Login may be required to access all resource tools.] For this learning module, students are asked to identify the lines of symmetry in letters of the alphabet. Includes video demonstrating a sample problem [1:27] and a...

In this video segment [3:25] from Cyberchase, a plant expert shows Bianca the patterns and symmetry found in nature.

Investigate the concept of symmetry at this test prep site. See detailed definitions and picture examples, answer the questions in the interactive practice pages, and do the classroom activity where students use a digital camera to...
