Students will complete 3 problems to review units 1 through 6. The curriculum reinforcer, is a daily practice piece that is incorporated into almost every lesson to help my students to retain skills and conceptual understanding from earlier lessons. My strategy is to use Spiraled Review to help my students retain what they learned during the earlier part of the year. This will help me to keep mathematical concepts fresh in the students mind so that the knowledge of these concepts become a part of students' long term memories.

After my students watch the opening video, we will discuss the meaning of absolute value and opposites both of which were introduced in the video.

During this instructional piece, I will ensure that my students learn the following:

- Absolute value denotes distance and therefore cannot be negative.
- The opposite of a positive number is that same number except it would be negative.
- The opposite of the opposite of a positive number is that same positive number as is.
- How to calculate using the absolute value of an number.
