Content descriptor create and interpret grid reference systems using grid references and directions to locate and describe positions and pathways

Elaborations

• • Elaboration interpreting a grid reference map of a familiar location of interest, such as a map of the showgrounds, a food festival, a botanical garden, a park in the local area or a train station, and writing instructions using grid references for a friend to find them at a specified location
• • Elaboration recognising that a spreadsheet uses a grid reference system, locating and entering data in cells and using a spreadsheet to record data collected through observations or experiments
• • Elaboration comparing and contrasting, describing and locating landmarks, people or things in a bird’s eye picture of a busy scene, such as people in a park, initially without a transparent grid reference system overlaid on the picture, and then with the grid overlaid; noticing how the grid helps to pinpoint things quickly and easily
• • Elaboration using different sized grids as a tool to enlarge an image or artwork
• • Elaboration simulating the actions of autonomous or robotic vehicles moving to different positions within a grid, using grid references and directional language to describe positions and pathways; for example, imitating an autonomous mobile warehouse robot moving stock to different aisles, using grid reference systems to locate positions
