Learning Domain: The Number System
Standard: Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, debits/credits, positive/negative electric charge); use positive and negative numbers to represent quantities in real-world contexts, explaining the meaning of 0 in each situation.

Quality of Explanation of the Subject Matter: Strong (2)
We added more discussion of "real life" situations where a negative is "added" to a negative, such as losing yards in football, diving underwater and continuing to go deeper. That made things much more understandable.

Utility of Materials Designed to Support Teaching: Strong (2)
Using number lines and stories of 'real life' examples of adding same signed numbers worked well, but next time we'll provide each student with number lines and perhaps red and black chips.

Quality of Assessments: Strong (2)
The assessment was challenging and included knowledge from previous lessons. I think it could have been improved with the assessment including at least a number line for students to draw two negative things "happening" and therefore being "added" together.

Quality of Technological Interactivity: Not Applicable (N/A)
I would like to see more interaction in this lesson with manipulatives or computer tech.

Quality of Instructional and Practice Exercises: Strong (2)
As with other aspects of this lesson, more opportunities for seeing visual expression of "adding negative to negative" would have helped.

Opportunities for Deeper Learning: Strong (2)
Students thought critically and reasoned abstractly as they made the connection between the "real life examples," the red "R's" and black "Bs" and the addition problems.
