The volume of a security is determined by the number of transactions involving the security. Higher volume typically indicates a more significant price move, while lower volume indicates a smaller price move. Each transaction adds to the total volume of the security. A transaction occurs every time a buyer accepts the offer of a seller. Therefore, the volume of a security for a day can be five transactions.
Y1 children learn to compare, describe and solve practical problems involving volume
In the Y1 maths curriculum, children learn to compare, describe and solve practical questions involving volume and capacity. A range of differentiated worksheets are available to support learning and develop practical skills. These sheets include reasoning, fluency and extension activities and include pictorial examples to stimulate deeper thinking. This unit focuses on the relationship between volume and capacity, and children are encouraged to use different representations of volume and capacity in their problems.
Children in Y1 can begin their exploration of volume and capacity by comparing containers of different sizes and shapes. By comparing the volumes of objects in a container, they can begin to describe their own containers and compare how much they can hold. They can use mathematical vocabulary to describe the volume of different containers and use simple formulas to determine how much a particular container can hold.
Pupils are also beginning to understand multiplication, division and doubling numbers, and fractions. They are also learning to count in 2s, 5s, and 10s. In addition, they are learning to identify the meanings of half and quarter, as well as the equal sharing of objects. Furthermore, they are beginning to understand that mass, weight, and capacity can be used interchangeably.
Y2 children learn to calculate volume in cubic units
Children in Y2 are taught to calculate volume in cubic units. They begin by using appropriate measuring units and are able to read measurements more accurately. As they progress, they will learn to compare volume and capacity with corresponding symbols. During this time, children will also learn to add and subtract volumes and convert between different measurements.
Children are introduced to volume measurement units in the real world by asking, “How much water is in this swimming pool?” and discussing the different units of measurement. They can also practice volume measurements by measuring the sides of a box and working out the volume. They can also practice this concept by converting millilitres to litres.
Y3 children measure volume in cubic units
This lesson teaches children how to measure volume in cubic units and find the volume of 3D shapes. The lesson contains three levels of differentiation: basic, intermediate and advanced. In the early stages of this stage, children start counting and comparing volumes in order to find their capacity. They also begin to recognise that different objects have different volumes and will use these measurements to solve problems.
By using real-life examples, children will be able to relate volume to the real world. For example, they may ask what the capacity of a swimming pool is in different units. They can also try to calculate the volume of a rectangular prism by counting all the unit cubes.
