Year 6 one-step function machines lesson pack | Algebra: Spring Block 2: Week 3

This Year 6 one-step function machines lesson pack introduces pupils to algebra through input and output, using clear function machine models and the language of rules and inverse operations. Aligned with the White Rose Spring Block 2 small step, the lesson supports pupils to calculate missing outputs, work backwards to find missing inputs, and identify the rule when given an input and output. The teaching approach builds confidence with key vocabulary including input, output, function and rule, while tackling common misconceptions such as applying the same operation again instead of using the inverse.
