These ‘Substitution Builders’ are designed to help students understand the importance of correctly applying the order of operations when substituting values into complex expressions.
In Substitution Builder (A), learners will substitute the number 8 into multiple expressions beginning with one operation and building to expressions with three operations, providing them with a clear demonstration of how the order of operations influences the final result.
Students will work with fractions as division, brackets and indices throughout. There are two follow up worksheets where the value of x is either a negative integer or a decimal number.
