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 demonstrate their understanding of a graph showing the relationship between the cost of different bottles of drink and the amount each bottle contains. They then explain which bottle of drink is the best value for money paid.
Students interpret 2 line graphs to write five statements comparing the relationship between times, distances and speeds for Jack and Ellie in a 10 kilometre running race.
Students interpret information from a flowchart to calculate the total costs of different sized groups staying in a motel for varying lengths. They also complete a linear algebraic equation to show the costs of one group's stay.
In this task students build the next two models of a spatial sequential pattern and then use their results to predict subsequent patterns and give general rules for these in words and in equations.
Students use information in a table about exploding bottles of ginger beer to find the fractions and percentages of bottles that exploded or stayed sealed in given weeks.
Students draw the next two triangles in a spatial pattern, calculate the areas of a range of triangles, work out the height of a triangle given its area, and write a rule for the pattern.
Different selections are made from a canteen menu that will cost a given amount. An extension activity is given that asks for all possible combinations to be found.
