Perimeter, Area and Volume - Volume of a Cuboid - Presentation

In a comprehensive lesson on measuring the volume of cuboids, students are introduced to the concept of volume through engaging activities that build upon their understanding of area. The lesson starts with a discussion about the formula for finding the area of a rectangle, which serves as a foundational step towards calculating volume. Students then move on to Activity 1, where they are tasked with completing sentences related to the dimensions of various cuboids, such as identifying the length, width, and height, and using these to calculate the area of the base. With this information, they proceed to find the volume by multiplying the area of the base with the height of the cuboid, reinforcing their understanding of volume as a three-dimensional measure.

Further activities challenge students to calculate the volume of cubes with given side lengths, emphasizing the use of appropriate units in their answers. For instance, students work out volumes for cubes with sides measuring 8 cm, 3 m, and 150 mm, among others. Activity 3 focuses on problem-solving skills where students must deduce the missing dimension, such as the height, given the volume of a cuboid. This is complemented by reasoning exercises, where students are encouraged to think critically about the properties of shapes, such as recognising that all sides of a cube are equal and thus the volume can be easily calculated. The lesson culminates with independent work, where students apply their knowledge to calculate the volume of various cuboids, demonstrating their ability to identify dimensions and apply the correct formula to find volume.
