Chapter Summary
Students should understand what reflection symmetry is, how to identify lines of symmetry (vertical, horizontal, both) in letters and simple shapes, and how to use them for making cutouts.
Students should be able to apply their understanding of reflection symmetry to identify lines of symmetry in various English alphabet letters and single-digit numbers.
Students should understand that an object has rotational symmetry if it looks the same after being turned by a certain fraction of a full circle (e.g., 1/4 turn, 1/2 turn, 3/4 turn).
Students should be able to identify letters and single-digit numbers that exhibit rotational symmetry and specify the turns at which they look the same.
Students should be able to differentiate between reflection symmetry and rotational symmetry, identify objects or designs that possess one, both, or neither type of symmetry, and provide examples.
Students should be able to create or modify designs to exhibit specific types of symmetry, such as rotational symmetry (e.g., 1/2 turn, 1/4 turn) or reflection symmetry, by adding shapes or colors.
Students should recognize symmetry in real-world contexts, such as traditional block printing, and match blocks to their prints based on symmetrical transformations.
