In middle school mathematics, students learn many new ways of using math, so it’s essential that they understand how to manipulate the basic number system. This means extending their understanding of math operations like division, multiplication, addition, and subtraction into the realm of advanced fractions (starting in grade six), rational numbers in grade 7, and by the 8th grade, even beginning to explore irrational numbers. Learning to manipulate the full number system in middle school gives students a good foundation for later, more complex mathematics. Of course, along with this, students need a thorough grounding in number system terminology. Read MoreRead Less
