Lessons
6Input and Output Values: Flow Diagrams
Determine input values, output values and rules for patterns and relationships using flow diagrams.
Input and Output Values: Tables
Determine input values, output values or rules for patterns and relationships using tables.
Equivalent Forms of a Relationship
Recognise, interpret and justify the equivalent forms of a relationship: verbally, in flow diagrams, tables, formulae and equations.
Functions and Relationships: Consolidation Practice
Consolidate skills: using rules, flow diagrams and tables to calculate input and output values.
Functions and Relationships: Consolidation in Context
Apply functions and relationships to real-life contexts using the constant difference method.
Functions and Relationships: Informal Test
An informal test consolidating lessons 1 to 5 of functions and relationships: identifying solutions of equations, describing rules verbally, matching rules to flow diagrams, determining unknown inputs and outputs, finding rules using the constant difference method, and completing a table of values for the perimeter of rectangles. Includes a full memorandum.
