7-10 Mathematics Addendum Content Strands (Grades 9-10) NUMBERS, NUMERATION, OPERATIONS, and NUMBER THEORY Today's mathematics program must be rich in experiences that go far beyond the traditional emphasis on number and operation. Number Sense And Numeration In grades 9-10 students should be given opportunities to read, write, and use real numbers. Have students use Venn diagrams or concept maps to illustrate the relationships among natural numbers, integers, rational numbers, irrational numbers, and real numbers. Given a set of real numbers, students should be able to order them from least to greatest. Students should begin to explore imaginary and complex numbers and their relationship to the set of real numbers.

GEOMETRY, MEASUREMENT and TRIGONOMETRY Geometry helps students describe the world in which they live and serves as a natural link to the integration of mathematics across the curriculum. Students need to investigate, experiment, and explore geometric properties using both technology and hands-on materials. Geometry lends itself to having students work in groups; we encourage you to use group work extensively (Davidson, 1990). Geometry And Spatial Sense In Grades 9-10 Have students represent and solve real world problems with two- and three-dimensional geometric models. Using technology, manipulatives, and/or coordinate geometry, have students explore, deduce, and explain the properties of geometric figures. For example, have students explore the relationships among the diagonals in the family of quadrilaterals or the concurrence of the medians, perpendicular bisectors, altitudes, and angle bisectors in a triangle. Provide activities for students to deepen their understanding of congruence and similarity. Have students further explore the basic transformations and extend the work to include dilations and glide reflections; explore the compositions of these transformations. Students should further apply the Pythagorean relationship to the solution of problems. Have students explore short deductive sequences and write simple proofs.

DATA ANALYSIS, STATISTICS, AND PROBABILITY Collecting, organizing, displaying, and interpreting data, as well as using that information to make predictions and decisions, are extremely important in today's society. However, before collecting data, students need to clearly define the problem and decide what information they will collect in order to solve the problem. Data collection and analysis lend themselves to small group work. Statistical instruction should be investigative and explorative in nature, so that students can answer questions about data. Probability should also be active and engaging, with students experimenting and modeling situations. Students need to investigate fairness, chances of winning, and uncertainty. Technology is an integral tool when students work with data and chance. In Grades 9-10 Have students construct and draw inferences from charts, tables, and graphs that summarize data from real-world situations. Students should use tables, box-and-whisker plots, and stem-and-leaf graphs to analyze data. Have students collect ordered pairs of data, and make a scatter plot. Have students use different linear regression techniques such as the median-median line and other curve fitting techniques to predict trends from data. Have students make use of the several technologies that are available to help do this. Students should understand, find (using technology), and apply measures of central tendency, variability, and correlation. Explore sampling techniques and have students recognize its role in statistical claims. Provide opportunities for students to design statistical experiments to study problems, conduct experiments, and interpret and communicate the outcomes.

FUNCTIONS, RELATIONS, and ALGEBRA One of the central themes of mathematics is the study of patterns, relations, and functions. This study requires students to recognize, describe, and generalize patterns and build mathematical models to predict the behavior of real-world phenomenon that exhibit the observed pattern. This study of patterns leads to an exploration of functions, a concept which is an important unifying idea in all aspects of mathematics. Functional relationships are of primary importance in many other disciplines such as the natural sciences, business [compound interest], the social sciences, and psychology [learning curves]. Functions And Relations In Grades 9-10 Students should represent and analyze relationships using tables, charts, verbal rules, graphs, and equations. Have students show how the change in one variable affects the value of the other variable in a relationship. Provide opportunities for students to identify relationships that are functions and explain why a relationship is or is not a function. Have students regularly translate among tables, equations, verbal rules, and graphs. Students should recognize when a table, equation, rule, or graph represents the same data and describes the same relationship.

Discrete mathematics is actually an umbrella term which can include such topics as counting techniques, sets, relations, functions, logic, reasoning, and algorithms. Information and communication continue to impact the modern world and require the understanding of topics in discrete mathematics. Decision-making, involving sets and systems having a countable number of elements, needs to be integrated throughout the curriculum. Students should have experience with finite graphs, matrices, sequences, recursion, and the development and testing of algorithms.

Continue to explore elementary logic notions relating to and, or, and ;not statements and relate them to Venn diagrams. Students should explore the relation among an if-then statement and its converse, inverse, and contrapositive statement. Provide opportunities for students to write simple computer programs to solve problems.
