#### Activities

*150 min*

- Introduce Skill
- While preparing myself for teaching/introducing today’s skill I view a short tutorial from Learn Zillion.
- I bring the students to area of the room where I can use the whiteboard and they can gather with their whiteboards.
- I introduce their ‘I Can’ statement for today.
- I can find the lines of symmetry in a shape.

- As a group we go over the skill and practice it on our whiteboards.

- Partner Practice
- Students work with a partner to practice their skill.
- Students cut out shapes from Symmetry Activity.
- Students fold the shapes to determine lines of symmetry.

- Independent Practice
- Students work on the worksheet on their own.
- Line Symmetry

- Check-In
- The students and I review the worksheet from the previous activity.
- I go over the first few problems with the students.
- Then one at a time I have students take turns explaining the remainder of the problems.

- The students and I review the worksheet from the previous activity.

- Interactive Practice
- The students work in groups to practice their skill on an online interactive.

#### Assessment

*30 min*

Generally the purpose of classroom computation isn’t quantity, it is quality with a focus on explaining the strategies used and how/why it is true. However, the purpose of targeted skills practice includes fluency, as well as additional review to build comprehension. I am looking for the student to demonstrate their fluency on this skill by completing the assessment with very few errors and within a reasonable amount of time. The assessment is meant to be completed in no more than 30 minutes.
