Year 7

Prior learning / place of lesson in scheme of work

Learn how to control a blinking LED. We will be learning how to create a blinking app using forever as well as simple commands, such as plot, unplot and pause.

What the teacher needs to know / QuickStart Computing Glossary

Program: A stored set of instructions encoded in a language understood by the computer that does some form of computation, processing input and/or stored data to generate output.

Algorithm: An unambiguous set of rules or a precise step-by-step guide to solve a problem or achieve a particular objective. The guided tutorial follows a algorithm and is a precise step-by-step guide to solve a problem

Loop: A block of code repeated automatically under the programs control. ** The blink program introduces Forever. The forever loop repeats code in the background forever.

Command: An instruction for the computer to execute, written in a particular programming language.

Programming & Development

  • Creates programs that implement algorithms to achieve given goals. (AL)

Data & Data Representation

  • Understands the difference between data and information. (AB)
  • Defines data types: real numbers and Boolean. (AB)

Information Technology

  • Collects, organises and presents data and information in digital content. (AB)
  • Makes appropriate improvements to solutions based on feedback received, and can comment on the success of the solution. (EV)
