Students will persevere to identify patterns in longest and shortest perimeters given a fixed area.

Just keep swimming, just keep swimming! Students may not always get the answer right away, so this lesson is about the art of perseverance!

**Opener**: I start the year off with order :) I want students to get into a routine and good habits, so I actually start with an opener on day 2! See my video clip on **Instructional Strategy - Process for openers** for information on how those are run in my class! Openers are a great way to incorporate **mathematical practice 3**, critiquing the reasoning of others, as I encourage students to work as table groups to talk through problems and help one another.

**Introduction to Mathematical Practices: ** To get into this lesson, I will first have a conversation with the students about the mathematical practices - what they are, what they mean, etc. I have them posted around my smartboard in "kid-friendly" language. For example, mp 1 is "I can solve a problem without giving up." I go over each practice and what it really means for the students and how they can expect to see it used in my class.

**Table Discussion: **To summarize this lesson, I have the students look at the 8 kid-friendly mathematical practices posted around my smart board and determine which of those they think were a part of today's lesson, and why. I will draw cards and have 2 different tables share out to the whole group. Instructional Strategy - Table Discussion.wmv
