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.
Given a rule, students complete a table and answer questions about cycling distances for a cycling fitness programme, describe the rule for the pattern, and identify an expression for the rule.
Students explain how they can work out how many striped or shaded beads are needed for a number of repeated 'sets', and identify the number of striped and shaded beads for given numbers of sets.
