7th Grade Math Masters 7th Grade Math Masters was created to help 7th grade students that have difficulty in 7th Math Investigations. We go over the same curriculum that 7th Math Investigations goes over. This class is made to be small to help out students individually with difficulties. We have an open door policy about 7th Math Masters and 7th Math Investigations. If there is a student who is excelling in 7th Math Masters they are recommended to join 7th Math Investigations. If there is a student who is struggling in 7th Math Investigations we can recommend them for 7th Math Masters. This has been very effective in previous years in helping to support students that need extra help and to succeed in math.
