Task 3 – How images are represented in digital format


I am proposing a lesson to a year 6 group.

Curriculum link:

Collect, sort, interpret and visually present different types of datausing software to manipulate datafor a range of purposes (ACTDIP016)

Children will explain the representation of an image as a series of pixels represented in binary.

Children already have a familiarised themselves with the binary system. Additionally they have worked with grids and mapping.

The lesson will combine the two skills. The children  will be given several binary numbers and they will map out images.

Extension and enrichment:

Children will be able to reverse engineer the process and find the binary  numbers for images in a grid. bitmaps-blank_1
