Substituting into Expressions (A) is the perfect place to start with learning to substitute. The worksheet is split into three sections which increase in difficulty. Students are required to substitute only one value into each expression, the value remains the same throughout each section and all values are positive integers. The worksheet is well laid out. Questions are presented in a table made up of three columns: one for expression, calculation and the final value of the expression.

The expressions in section A contain only two terms and one operation, in section B expressions contain two terms but two operations and in section C the expressions contain up to three terms and three operations.
