Year 7
Prior learning/place of lesson in scheme of work
Learn how to creating a variable to keep track of the current count. We will be learning how to create a counter app using global variables as well as simple commands, such as on button pressed, and show number.
What the teacher needs to know
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 program’s control. ** The blink program introduces Forever. Forever will repeats code in the background forever.
Command: An instruction for the computer to execute, written in a particular programming language.**
