Content descriptor recognise situations, including financial contexts, that use integers; locate and represent integers on a number line and as coordinates on the Cartesian plane

Elaborations

• • Elaboration extending the number line in the negative direction to locate and represent integers, recognising the difference in location between (-2) and (+2) and their relationship to zero as -2< 0< 2
• • Elaboration using integers to represent quantities in financial contexts, including the concept of profit and loss for a planned event
• • Elaboration using horizontal and vertical number lines to represent and find solutions to everyday problems involving locating and ordering integers around zero; for example, elevators, above and below sea level; distinguishing a location by referencing to the 4 quadrants of the Cartesian plane
• • Elaboration recognising that the sign (positive or negative) indicates a direction in relation to zero; for example, 30 metres left of the admin block is (-30) and 20 metres right of the admin block is (+20); programming robots to move along a number line which is either horizontal or vertical but not both at the same time
• • Elaboration representing the temperatures of the different planets in the solar system, using a diagram of a thermometer that models a vertical number line
