Modifications:

•  Seeing-impaired student’s work should be printed on blue paper.
•  Exceptional children may require more time and possibly need to work with a teachers aide for assistance during lab activities (or paired with another student).

• Teacher will grade the worksheets of the students. Teacher will look for the process of mathematical computation and unit placement.
•  Classroom participation will also be assessed.
