Directed Number – Addition by Pattern Spotting WORKSHEET DESCRIPTION
This worksheet will help learners understand addition with directed numbers through pattern recognition. The structured approach allows students to discover rules for adding positive and negative numbers by observing consistent patterns across multiple examples.
Section A presents six systematic sets of addition problems where one number remains constant while the other changes incrementally. Each set includes some completed examples to help learners identify patterns, with gaps for students to fill in missing answers. Crucially, learners must also determine whether each answer represents the sum or difference of the original numbers when signs are ignored.
Section B applies the patterns discovered in Section A to solve mixed addition problems involving positive and negative numbers. These questions require students to use their understanding of the underlying patterns rather than relying on rote memorisation.
