GLOBAL CONTEXT Identities and relationships

STATEMENT OF INQUIRY Logic is a powerful tool for justifying our simplifications and solutions in algebra.

ASSESSMENT

Semester 1 Examination (Criteria A, C)

Equations, Inequations and Formulae – solving linear equations, inequations and formulae (Chapter 6)

Logic:

  

Equivalence

Algebraic Expressions - expansion, algebraic fractions, binomial and special products. (Chapter 4)

Model

Simplification

Solve problems involving linear equations, including those derived from formulas

ONE continued

Solve linear inequalities and graph their solutions on a number line

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.

Fairness and development

Choosing the most appropriate tools for representing data can help us to understand our world and make informed decisions about future directions.

Statistics – graphs include stemplots and parallel boxplots (Chapter 15)

Relationships:

Assignment and Investigation Week 1, Term 3 (Criteria B, D)

   

Change

Identify everyday questions and issues involving at least one numerical and at least one categorical variable, and collect data directly from secondary sources.

Generalisation

Justification

Representation

TWO

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.
