Computational thinking and algorithms

Rate this resource

An unplugged activity to convert binary numbers into coordinates that enable students to recreate an image using values given in binary. The resource also includes a spreadsheet which can be used to make more complex images for use with students at a more advanced level. The presentation is more of a discussion of computational thinking and is not really relevant to this activity. Once students have completed the activity for themselves, they could be asked to create their own image in a similar way to the one they have recreated, and generate a coordinate list for their image in binary. The discussions listed in the activity sheet should also be useful to broaden students understanding of the use of binary as well as how it might be possible to speed up a computer system in similar situations.
