Developmental Continuum of Growth Points   Measurement – Volume/Capacity

 LEVEL 0NE Have an awareness of the attributes of capacity and its descriptive language ·         Use appropriate language of approximation (eg. about, almost, nearly, not quite, just under, a bit under) and comparison (eg. same, near/far, holds more/holds less, too heavy) to describe the capacity of objects Compare, order and match objects by capacity ·         Fill and pack containers and pour from one to the other to informally compare the capacity of containers ·         Estimate and compare the capacity of two containers using pouring ·         Estimate and measure the capacity of containers using informal units; for example, spoonfuls, cups

 LEVEL TWO Use informal units to measure capacity ·        Estimate and measure informally the capacity by making, describing and comparing informal units ·        Compare the relative capacity of familiar objects and containers by eye to decide which holds more ·        Compare two different containers by pouring from one to the other or into two identical containers ·        Estimate and measure how many identical units fill / pack a container ·        Use the number of units to compare the capacity of containers Uses uniform units appropriately to quantify capacity, assigning number and unit to the measure ·        Estimate, describe and compare measurements of capacity using informal units ·        Recognise the differences between non-uniform measures and uniform measures ·        Use the formal unit, litre for capacity

 LEVEL THREE Use appropriate informal and some formal units to measure volume and capacity ·        Estimate and measure volume and capacity using appropriate instruments. ·        Know how cubic units pack into a rectangular container ·        Relate unit size to number of units

 LEVEL FOUR With increasing accuracy use formal units for estimating and measuring volume and capacity ·        Understand the decimal structure built into metric measures ·        Use measurements to compare things including those they have not directly experienced ·        Know that for figures the same shape, the greater the length measurement, the greater the volume, but that is not true for different shapes ·        Understand that volume is measured in cubic units ·        Understand why the volume of rectangular prisms can be found by multiplying its length dimensions ·        Partition units to make measurements more accurate ·        Choose units that are sufficiently small to make the needed comparisons ·        Use understanding of multiplicative structure built into the metric system to move flexibly between related standard units; for example, Interpret 0.2L mark on a scale as 200ml. ·        Make realistic estimates and measurements including things they have not actually seen or experienced ·        Use relationships between measurements to find measures indirectly; for example, knowing that 1ml=1cm³ they can find the volume of an irregular solid in cubic cm by finding how many mL of water it displaces using a capacity cylinder
