Lesson details

Key learning points

  1. Conditions are built using expressions that evaluate to either True or False.
  2. Selection provides program control where there is more than one path to follow.

Keywords

  • Expression - a combination of logical and comparison operators that result to True or False

  • Selection - used when there is more than one possible path for a program to follow

  • If statement - used to carry out selection in a program

  • If block - used to carry out selection in Scratch

Common misconception

A program can only follow one sequence of commands.

Selection allows for a program to follow alternative paths depending on the criteria of the selection statement.

Use of a deck of playing cards can involve more of the class when understanding selection based on rank, suit and colour. Pupils could each have a card and stand up or sit down depending on the card they are holding and the condition being presented.
