In addition, students work with and study whole numbers and decimal numeration. Following this introductory segment, students work with tables, expressions and equations to help develop a foundation for algebra. Order of operations and the use of formulas are integrated into this section as well. The use of variables is stressed continually. Plane geometry, number theory, fractional operations, and fractional equations are covered next.
Students work in both customary and metric systems and solve problems using data from a table.
Important concepts of ratio, proportion, and percent, as well as geometric work with two-dimensional figures are covered during the third quarter. The year culminates with units on statistics and probability, integers, and rational numbers. Exponents, mental math, and estimation are utilized as we address the operations of multiplication and division. Basic geometry ideas are explored, angle measurement work with polygons, circles, transformations, and three-dimensional figures are discussed. Relationships between number theory and fraction concepts, as well as development of number sense are key features.
