ASSESSMENT

Semester 1 Examination (Criteria A, C)

Equations, Inequations and Formulae – solving linear equations, inequations and formulae (Chapter 6) Algebraic Expressions - expansion, algebraic fractions, binomial and special products. (Chapter 4) Solve problems involving linear equations, including those derived from formulas Apply the four operations to simple algebraic fractions with numerical denominators Apply the distributive law to the expansion of algebraic expressions, including binomials, and collect like terms. Statistics – graphs include stemplots and parallel boxplots (Chapter 15) Identify everyday questions and issues involving at least one numerical and at least one categorical variable and collect data directly from secondary sources. Construct back-to-back stem-and-leaf plots and histograms and describe data using terms including “skewed”, “symmetrical” and “bi-modal”. Compare data using mean, median and range to describe and interpret numerical data sets in terms of location (centre) and spread. Determine quartiles and interquartile range. Construct and interpret box plots and use them to compare data sets. Solve linear inequalities and graph their solutions on a number line
