Substitution resources

Students complete a table and a graph of an equation about the costs of bike repairs, then interpret the graph to respond to questions.

Students complete a table based on an algebraic formula for free fall velocity, plot the results, and interpret the graph.

Students write the simplest algebraic expressions for the lengths and area of parts of a composite shape, then solve these expressions using substitution. They then solve an equation that relates an algebraic expression to a given side length.

Students use plastic money to explore and continue a number pattern about going to a disco. They then describe the pattern.

Students show how to solve a series of algebraic expressions by substituting given numbers.

Students use substitution into equations to evaluate the number of blocks and total surface areas in shapes of different heights. The stimulus can be used as a challenging task to try and derive the rules from the spatial pattern. This is classified as Patterns and Relationships.

Students solve given algebraic expressions using substitution.

Students write and solve linear equations to describe cooking times.

Students use substitution to calculate the cost and length of time taken to repair washing machines, and formulate and solve a related linear equation.

Students use linear equations to solve mathematical problems for money deposited and withdrawn from a bank account. They also identify parts of the related linear equation.

Students solve a number of mathematical problems about the cost of a visit to the fair using algebraic expressions provided.

Students use substitution to calculate a missing variable in algebraic expressions of practical situations.

Students use substitution to evaluate a linear equation for parking charges. Students expand, simplify, and change the subject of the equation.

Students demonstrate their understanding of a linear algebraic equation to calculate the amount of money in a savings account.
