QUARTER 2: Standard 7.0 – Processes of Mathematics: Students demonstrate the processes of mathematics by making connections and applying reasoning to solve problems and to communicate their findings. (These processes serve as the foundation for the delivery of all mathematics content objectives.) Objectives – The student will be able to: a. Select and apply a variety of concepts, processes, and skills to solve problems. (Problem Solving) b. Justify ideas or solutions with mathematical concepts or proofs. (Reasoning) c. Present mathematical ideas using words, symbols, visual displays, or technology. (Communication) d. Relate or apply mathematics within the discipline, to other disciplines, and to life. (Connections) Unit 4 – Number Relationships and Computation (Fractions and Measurement) Standard 6.0 – Number Relationships and Computation/Arithmetic Students will describe, represent, or apply numbers or their relationships or will estimate or compute using mental strategies, paper/pencil, or technology. Standard 3.0 – Measurement Students will identify attributes, units, or systems of measurements or apply a variety of techniques, formulae, tools, or technology for determining measurements. Objectives – The student will be able to: a. Express fractions as (terminating, repeating, or non-terminating/non-repeating) decimals and decimals as fractions. b. Explore the concept of rational vs. irrational numbers. c. Compare and order fractions and mixed numbers mathematically and on a number line. d. Identify the least common multiple (LCM) and greatest common factor (GCF) using prime factorization. e. Estimate and calculate the sums and differences of fractions, whole numbers, and mixed numbers in problem solving situations, expressing results in simplest form. f. Estimate and calculate the product of fractions, whole numbers, and mixed numbers. g. Explore the relationship between the fraction of a whole number and the percent of a whole number. h. Estimate and calculate the quotients of fractions, whole numbers, and mixed numbers in problem solving situations, expressing results in simplest form. i. Calculate equivalent units of length, capacity, and weight within the customary system. j. Calculate equivalent units of time. k. Determine start, elapsed, and end time. Unit 5 – Probability Standard 5.0 – Students will use experimental methods or theoretical reasoning to determine probabilities to make predictions or solve problems about events whose outcomes involve random variation. Objectives – The student will be able to: a. Find the probability of independent events and express as a fraction, decimal, or percent. b. Compare the outcomes of theoretical probability with results of experimental probability. c. Determine the possible outcomes of independent events using an organized list and tree diagram. d. Express the probability of an event comprised of no more than two independent events as a fraction, a decimal, or a percent. e. Express the probability of a second event that is dependent on a first event of equally likely outcomes as a fraction, a decimal, or a percent. f. Describe the difference between independent and dependent events. Unit 6 – Statistics Standard 4.0 – Students will collect, organize, display, analyze, or interpret data to make decisions or predictions. Objectives – The student will be able to: a. Analyze, interpret, construct, and make predictions (in oral and written form) based on tables, frequency tables, stem-and-leaf plots, back-to-back stem-and-leaf plots, line plots, double bar graphs, line graphs, double line graphs, circle graphs, and histograms. b. Determine the appropriate type of graph to effectively display data using tables (frequency tables), single and double bar graphs, single and double line graphs, stem-and-leaf plots, and line plots. c. Describe the shape and important features of a data set (using terms such as cluster, range, and outlier). d. Calculate and interpret measures of central tendency (mean, median, and mode) to interpret data sets. e. Apply the range and measures of central tendency to solve a problem or answer a question. f. Determine the effect of an outlier on the mean. g. Determine the effect of changes in a data set on the mean. h. Interpret, organize, construct, and display data to make box-and-whisker plots.
