Launch

10 minutes

OpenerAs 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 percent to solve real world 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). 

Thoughts from Me! Students will need to pay careful attention to precision when moving the decimal point and completing the calculations (mathematical practice 6).  Percents lend themselves to real world application problems, requiring students to model and reason given models (mathematical practices 2 and 4). Students will be permitted to use tools as needed - calculators and bar models (mathematical practice 5).

Open Discussion:  To summarize this lesson, I want to give students an opportunity to ask any questions that they still have regarding percents, as tomorrow they will have a test.  Thus, I will open the floor for discussion, normally once one student asks a question, a good discussion begins!
