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. The second phase of this program starts with making sense of mixed numbers and encouraging estimation.
Students learn to estimate sums and differences in problems involving mixed numbers.
The work with fractions will help students develop skills they will need in their work with probability and algebra. Measurement is covered with both customary and metric units and carried through to relate to applications of geometric figures. Proportional thinking is stressed as students deal with ratio, proportion, and percent. Problem-solving skills are improved through writing equations. The program addresses the content areas of statistics, probability, and integers during the last quarter of the year.
