Scratch 7 B IT 1

Learning Outcomes LO 1: Pupils will be able to describe how to position a sprite and be able to apply the correct algorithm. LO 2: Pupils will be able to describe sequence and iteration. LO 3: Pupils will be able to apply sequence and iteration to their games.

Starter: Positioning Sprites

Sequence, Selection, Iteration Sequence A sequence is a set of actions or events that must be carried out in the same order every time. It is one of the 3 basic logical structures used by algorithms and programming.

Iteration (Repetition) � Repetition (loop) Repetition refers to sections of code or algorithmic instructions that are repeated. There are different types of loop. The most basic is where a set of instructions in repeated a set number of times. Another type of loop repeats continuously until an escape clause is met. It is one of the three basic structures used by algorithms and programming. http: //computationaltales. blogspot. co. uk/2011/03/loops-andmaking-horseshoe. html

Selection is about choice. It is the place where an algorithm or program branches in different directions. It is one of the 3 basic structures used by algorithms and programming.
