Everyday Mathematics is a wonderful curriculum, though there are some gaps in the standards. Therefore in order to meet the standards we had to supplement throughout the year. These assessments cover what the unit does in everyday math, as well as the standards that are not addressed at some point throughout the curriculum.
I suggest reviewing the assessments prior to teaching the unit, we addressed each standard and may need to supplement to assure you are teaching each grade level standards. Buying the bundle (all unit assessments) would assure there are no gaps in the standards.
