Each class will be given a math quiz. The quiz has to be from the same subject to accurately reflect the affects on grades. ]]> 2019-03-24 16:20:16 UTC https://padlet.com/mlleg365/vh42yufx7ojl/wish/344574468 mlleg365 https://padlet.com/mlleg365/vh42yufx7ojl/wish/344612431 We selected one class from each grade level to equally represent the whole school.

Some students may be above average at math while others may be below average. This may skew the averages when comparing them to the other class. Study habits may also affect the results.
