I have found this activity worksheet as a resource on Teachers Pay Teachers (TpT), an online platform. This worksheet can be useful to the Year 5 students as a fun way to represent data using a binary system (0s and 1s). The left half of the worksheet focuses on converting an image into a binary representation. The right half has binary codes that will be converted into an image (TpT, 2021).
