An introduction to decomposition:Tut, clap or Jive

Key Stage 1: Although decomposition is not explicitly mentioned in the key stage 1 programme of study, it is used when pupils break a task down to work out the steps in a simple algorithm or when they choose a part of a program to work on when they ‘create and debug programs’.

Key Stage 2 : Solve problems by decomposing them into smaller parts.

Today we are learning about:

decomposition

● I can break a sequence down into parts.

● I can say why this is useful.

Today we are learning about:

decomposition● I can decompose a sequence.

● I can say why decomposition is useful.

● I can say how decomposition is used when creating computer programs like animations or games.
