Technology Resources Needed: 
Interactive Whiteboard Calculator 
Background/Preparation: 
Teacher: The teacher will need to preview the videos to assess good stopping points for students to ask questions. The teacher will need to select a worksheet from the first, third, and fourth boxes on the website http://www.commoncoresheets.com/Algebra.php and make copies for the students. Student: The student will need to know the following terms: replacement set, solution, and substitution. The student will need to be able to use the order of operations adequately. 
Before: The teacher will have the bell ringer (in attachments) on the interactive whiteboard. The students will answer the questions in their notebooks. The teacher will ask selected students to answer the problems. The teacher will do an informal assessment to see if the students are ready to continue. The teacher will write on the interactive whiteboard, “Replacement Set and Solution.” The teacher will discuss the meanings of these terms. The replacement set will be the numbers used to test the equation. A true result when substituting the number for the variable means that the number is a solution. A false result when substituting the number for the variable means that the number is a not solution. During:
After: The teacher will hand out the exit slip Substitution 6^{th} Grade from the attachments. The students will answer and turn in as they leave the classroom. The teacher will grade the exit slip for a formal assessment. 
Attachments: **Some files will display in a new window. Others will prompt you to download. 
Assessment Strategies 
Informal: The teacher will do informal assessments during the videos. The teacher will do informal assessments during group work on independent practice and adjust instruction as needed. Formal: The teacher will use the exit slip, "Substitution 6th Grade", as the formal assessment to make sure the standard is mastered. 
Acceleration: 
The teacher will make copies of the worksheet from the fourth box "Writing Inequalities from a Numberline" on the website http://www.commoncoresheets.com/Algebra.php. Students will be challenged to write an inequality to express the number line. 
Intervention: 
The teacher will assign students to groups with a peer tutor. The teacher will use differentiated instruction as needed with students by monitoring their work. The teacher will do oneonone instruction if needed.
