In school, students need to solve word-problem (story) sums which constitute the bulk of the Maths work that they do.

This is a multi-skilled task as it first requires the student to have good skills in reading comprehension so that he / she can understand the question. This is followed by the need to have good analytical ability, so that the student can sieve out the vital information from the question to formulate the equation (number sentence). Then the student needs to apply his knowledge of the rules of Maths to solve the equation. In order to succeed in solving the question, the student needs to succeed in each of the 3 steps mentioned and each task requires a different set of skills.
