Understanding the binary number system is crucial for developing computational thinking in pupils. Although it is a more abstract mathematical concept, it can be introduced in a playful and hands-on way. This paper aims to present to primary school teachers how Grade 4 pupils can acquire basic knowledge of the binary number system. We carried out a set of activities based on the Computer Science Unplugged approach. These activities focused on writing and converting numbers, encoding images and text in binary, and understanding basic computing concepts such as bit, byte, and image resolution. Pupils developed logical thinking and problem-solving skills through practical tasks involving dot cards, coding messages, and creating binary necklaces. The paper is based on the method of participant observation. During the activities, we observed the pupils, documented our observations, and analyzed their work and results together with the pupils. The findings show that pupils successfully developed an understanding of the binary system despite challenges such as mental arithmetic and fine motor skills. The activities positively impacted their attention, accuracy, collaboration, and thinking in other subjects.
