Type of Differentiated Instruction
At the beginning of the Unit, there would be a learning contract that Sandra volunteers to help out as much as possible. That way she will get as much out of each lesson as possible. In this first lesson, she would be one of the "volunteers" to enact the Watch Your Step activity. This activity will help her to understand where systems of equations come from.
In this lesson, Sandra would be placed with a student that normally struggles to follow/memorize instructions. By being able to teach it to her peer, she will be able to have a better understanding of the material. This lesson also uses Tiered Assignments for her. She has the opportunity to not do the word problem as a graded assignment. Instead, she receives another practice problem. She is, however, not excused from trying the word problem. As long as she makes an attempt to solve it, she will receive extra credit. I'm not worried that she know how to do word problems at this time since there is a day devoted entirely to those types of problems.
Since this lesson revolves around being in groups, there are two ways that the lesson could be differentiated for her. The teacher could either put her in a group that has like-minded students. This method would be using flexible grouping. The other way to group her team is to put her with students that tend to have other issues. If she is the Ringleader first, she would have an easier time recalling the steps, which would boost her confidence.
In this lesson, multiple levels of questions are used to help guide Sandra to the bigger picture. By starting off with simpler questions, she would build her confidence as she began to get the harder ones.
