Beginning with the 8th grade students begin to study algebra, geometry, and so forth. Most states still do not begin Algebra until the 9th grade. They measure quantities with appropriate units. They classify shapes and see relationships among them by paying attention to their geometric attributes. They collect and analyze data and verify the answers.
Students estimate, measure, and describe objects in space.
They use patterns to help solve problems. They represent number relationships and conduct simple probability experiments. They describe and compare simple fractions and decimals. They understand the properties of, and the relationships between, plane geometric figures. They collect, represent, and analyze data to answer questions.
