**Opener: **As students enter the room, they will immediately pick up and begin working on the opener – Instructional Strategy - Process for openers. This method of working and going over the opener lends itself to allow students to construct viable arguments and critique the reasoning of others, which is **mathematical practice 3**.

**Learning Target: **After completion of the opener, I will address the day’s learning targets to the students. For today’s lesson, the intended target is “I can apply proportional reasoning to solve scale drawing problems.” Students will jot the learning target down in their agendas (our version of a student planner, there is a place to write the learning target for every day).

**Scale Drawings Test: **Today students will take the Scale Drawings Test. The test consists of 20 multiple choice questions. For multiple choice questions, I use the website www.masteryconnect.com to give the students immediate feedback. Mastery Connect is a free (to a point) website where teachers can upload assessments that are aligned with common core standards, and scan student answer sheets using a web camera or document camera. In a second’s time, the student’s score will appear on the screen – as well as let them know which of the problems they scored incorrectly. My students really enjoy scanning their own papers and getting that immediate feedback. I normally turn the option off where they can see which problems they got incorrect, and using the stoplight feature on the website I will send students back to their seat to look over their test if they appear in the yellow (near mastery) or red (remedial) category. This helps promote the idea of taking your time and looking over your work!

#### Summary

*5 min*

Scale Drawings Test: Since "Note to the Teacher" is a method that I use throughout the year, I find that I do not need to use sentence starters. Using the prompt on the smartboard "how did you do?" students generally open right up and spill their beans! As a way to not cause disruption by having to look for paper, I have the students write me their notes on the back of their test opener.

Using a Protractor Smartboard: Students were able to complete this test rather quickly, so I worked with them on using a protractor to draw angles during the last part of class. After drawing a few basic angles, I increased the difficulty by asking them to draw angles with certain side lengths. This is just getting them ready for tomorrow's lesson.
