Content Descriptor

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

Elaborations

• 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
• 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
• 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
• using different sized grids as a tool to enlarge an image or artwork
• 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

Year 4 Mathematics Achievement Standard

By the end of Year 4, students use their understanding of place value to represent tenths and hundredths in decimal form and to multiply natural numbers by multiples of 10. They use mathematical modelling to solve financial and other practical problems , formulating the problem using number sentences, solving the problem choosing efficient strategies and interpreting the results in terms of the situation. Students use their proficiency with addition and multiplication facts to add and subtract, multiply and divide numbers efficiently. They choose rounding and estimation strategies to determine whether results of calculations are reasonable. Students use the properties of odd and even numbers. They recognise equivalent fractions and make connections between fraction and decimal notations. Students count and represent fractions on a number line. They find unknown values in numerical equations involving addition and subtraction. Students follow and create algorithms that generate sets of numbers and identify emerging patterns. They use scaled instruments and appropriate units to measure length, mass, capacity and temperature. Students measure and approximate perimeters and areas. They convert between units of time when solving problems involving duration. Students compare angles relative to a right angle using angle names. They represent and approximate shapes and objects in the environment. Students create and interpret grid references. They identify line and rotational symmetry in plane shapes and create symmetrical patterns. Students create many-to-one data displays, assess the suitability of displays for representing data and discuss the shape of distributions and variation in data. They use surveys and digital tools to generate categorical or discrete numerical data in statistical investigations and communicate their findings in context. Students order events or the outcomes of chance experiments in terms of likelihood and identify whether events are independent or dependent. They conduct repeated chance experiments and describe the variation in results.
