The following list provides you with the basic 8th grade math concepts that should be attained by the end of the school year. Mastery of the concepts at the previous grade is assumed. Note the skill set is similar to that of the 7th grade. The entry into middle school is often accompanied by a comprehensive review of all math skill students have been expected to learn up to this point.


No real new numbers concepts are introduced, but students should be comfortable working with factors, taking square roots, and performing basic arithmetic.
