QR Competency – 9 th Grade The student will: Develop an understanding of numbers and operations, as well as estimation ◦Demonstrate a deeper understanding of very large and very small numbers and of various representations of them. ◦Compare and contrast the properties of numbers and number systems. ◦Judge the effects of such operations as multiplication, division, and computing powers and roots on the magnitude of quantities. ◦Judge the reasonableness of numerical computations and their results. Demonstrate an understanding of measurement concepts ◦Make decisions about units and scales that are appropriate for problem situations involving measurement. ◦Understand and use formulas for the area, perimeter, surface area, and volume of geometric figures. ◦Use appropriate techniques and tools to determine measurement.

QR Competency – 9 th Grade Evaluate data and acquire knowledge of probability and data analysis ◦Formulate questions that can be addressed with data and collect, organize, and display relevant data to answer them. ◦Know the characteristics of well-designed studies, including the role of randomization in surveys and experiments. ◦Understand histograms, parallel box plots, and scatter plots and use them to display data. ◦Compute basic statistics including measures of central tendency. ◦Use simulations to explore experimental probability. ◦Evaluate published reports that are based on data by examining the design of the study, the appropriateness of the data analysis, and the validity of conclusions. ◦Understand how to compute the probability of simple and compound events.

QR Competency – 9 th Grade Apply and demonstrate algebraic concepts and procedures ◦Understand patterns, relations, and functions and the connections between them. ◦Analyze functions of one variable by investigating rates of change. ◦Understand and perform transformation commonly used with functions. ◦Understand and compare the properties of classes of functions, including linear, exponential, polynomial, and rational. ◦Use mathematical models to represent and understand quantitative relationships. ◦Draw reasonable conclusions about a situation being modeled. ◦Approximate and interpret rates of change from graphical and numerical data. Investigate geometric shapes and their properties ◦Explore relationships among two and three dimensional geometric objects and solve problems involving them. ◦Apply transformations and use symmetry to analyze mathematical situations.

Your Birthdate: Important Numbers Mexican General Antonio Lopez de Santa Anna recaptured the town on March 6, 1836, after a thirteen-day siege; the Mexican army suffered an estimated 600 casualties. Of the official list of 189 Texan defenders, all were killed. Historians continue to debate the number of defenders inside the Alamo. (SOURCE: )
