Symmetry

• What’s In My Brain: H vs Arrow

  Students will analyze examples and non-examples to deduce the topic: shapes with 180º rotational symmetry

  Show 3 Steps

  1. First, students get a set of shapes categorized in two groups.

  2. Then they get a set of ungrouped shapes. Which columns will they go in?

  3. Finally, I reveal the topic: 180º rotational symmetry

• Letters With Symmetry

  Students will group letters by their type of reflective symmetry and then form symmetrical words and sentences.

  Show 4 Steps

  1. First, students will find the lines of symmetry for the capital letters.

  2. Next, they put them in categories based on their lines of symmetry.

  3. Then, students will form words with symmetry.

  4. Finally, they’ll create the longest sentences they can using only symmetrical words.
