A Secret Integer Message
In this worksheet, students use their ability with Cartesian planes, and their knowledge of positive and negative integers, to reveal a secret message using coordinates from the grid.
This worksheet is part of a larger Year 6 unit which helps students develop their understanding of integers, specifically negative integers, and how they are used in everyday calculations.

Learning goals
- We are learning to use, locate and represent integers on number lines, Cartesian planes, thermometers and in profit and loss.
- We are learning to investigate everyday situations that use integers, e.g. temperatures, and to locate and represent these numbers on a number line.
