Skills/Standards	Number and Number Sense and Operations Standard Measurement Standard Geometry and Spatial Sense Standard Patterns, Functions and Algebra Standard 9. Solve and interpret the meaning of 2 by 2 systems of linear equations graphically, by substitution and by elimination, with and without technology.5 6 7 8 9 10 11 12 10. Solve 2 by 2 systems of linear equations graphically and by simple substituition(From Grade 8) 11. Interpret the meaning of the solution of 2 by 2 system of equations;i.e., point, line, no solution (From Grade 8) 7. Solve systems of linear inequalities (From Grade 10) 11. Solve real-world problems that can be modeled, using systems of linear equations and inequalities.(From Grade 10) Data Analysis and Probability Standard 1. Classify data as univariate (single variable) or bivariate (two variables) and as quantitative (measurement) or qualitative (categorical) data. 2. Create a scatterplot for a set of bivariate data, sketch the line of best fit, and interpret the slope of the line of best fit. 3. Analyze and interpret frequency distributions based on spread, symmetry, skewness, clusters and outliers. 4. Describe and compare various types of studies (survey, observation, experiment), and identify possible misuses of statistical data. 5. Describe characteristics and limitations of sampling methods, and analyze the effects of random versus biased sampling; e.g., determine and justify whether the sample is likely to be representative of the population. 6. Make inferences about relationships in bivariant data, and recognize the difference between evidence of relationship (correlation) and causation. 7. Use counting techniques and the Fundamental Counting principle to determine the total number of possible outcomes for mathematical situations.K1 2 3 4 5 6 7 89 10 11 12 8. Describe, create and analyze a sample space and use it to calculate probability. 9. Identify situations involving independent and dependent events, and explain differences between, and common misconceptions about, probabilities associated with those events. 10. Use theoretical and experimental probability, including simulations or random numbers, to estimate probabilities and to solve problems dealing with uncertainty; e.g., compound events, independent events, and simple dependent events. 6. Make conjectures about possible relationships in a scatterplot and approximate line of best fit. (From Grade 8) Data Analysis and Probability Standard (Continued) 7.Identify different ways of selecting samples, representative sample and convenience sample. (From Grade 8) 8. Describe how the relative size of a sample compares to the target population affects the validity of predictions. (From Grade 8)
