This extension kits offers an exciting opportunity to dive deeper into the inner workings of a digital system by expanding the arithmetic capabilities of the B4 towards multiplication, division and beyond. In the process of implementing these capabilities from the ground up in a computer, students learn about loops, conditional jumps, data pointers and memory addresses. This curriculum follows the B4-style bottom-up motivational approach, in which computing concepts are introduced by need and motivated by context. Students gain an understanding of the practical necessity of computing concepts and learn about them from a hardware and a software perspective. The result is a deeper and more natural understanding of Digital Technologies. 


This product has been designed with the new Australian Curriculum: Digital Technologies in mind.
