The big ideas and topics in Eighth Grade are
proportionality; expressions, equations, relationships, and foundations of
functions; and measurement and data.
Students use concepts, algorithms, and
properties of real numbers to explore mathematical relationships and to
describe increasingly complex situations. Students use concepts of
proportionality to explore, develop, and communicate mathematical
relationships. Students use algebraic thinking to describe how a change in one
quantity in a relationship results in a change in the other. Students connect
verbal, numeric, graphic, and symbolic representations of relationships,
including equations and inequalities. Students begin to develop an
understanding of functional relationships.
Students use geometric properties
and relationships, as well as spatial reasoning, to model and analyze
situations and solve problems. Students communicate information about geometric
figures or situations by quantifying attributes, generalize procedures from measurement
experiences, and use the procedures to solve problems.
Students use appropriate
statistics, representations of data, and reasoning to draw conclusions,
evaluate arguments, and make recommendations. While the use of all types of
technology is important, the emphasis on algebra readiness skills necessitates
the implementation of graphing technology.
