Two homework sheets on low level languages. The first compares the key features of low level languages and high level languages. The second focuses on suitability of languages for particular tasks, and includes some exam style questions. Both include separate answer sheets. Useful as homework tasks, classroom tasks, or revision work. Can be used in conjunction with my Low level programming languages lesson. Fully editable resource.

Practical lesson on low level languages, focusing on assembly language. The bulk of the lesson is practical programming exercises using the Little Man Computer (LMC). By comparing their existing knowledge of a high level language with these assembly language programming tasks, pupils should be able to grasp the differences between the two types of programming language. The plenary reinforces these differences. Includes a worked example, 6 differentiated assembly language program activities, an instruction set help sheet, a short lesson plenary, and a longer version that can be used as homework (both with answers). Fully editable resource.

Collection of 6 binary themed classroom posters (plus variations). Perfect for GCSE Computer Science and IB Computer Science classroom displays. Collection includes: 2 posters for calculating the binary value of denary numbers 2 posters for calculating the denary value of binary numbers 2 posters for matching binary to denary (or vice versa) Posters are fully editable Word documents and each includes a version with a black background and a version with a white background (to save ink). A3 sized, but obviously can be printed smaller.
