Lesson 3 - Improving a game

In this lesson, pupils will apply the concept of variables to enhance an existing game in Scratch. They will predict the outcome of changing the same change score block in different parts of a program, then they will test their predictions in Scratch. They will also experiment with using different values in variables, and with using a variable elsewhere in a program. Finally, they will add comments to their project, explaining how they have met the objectives of the lesson.

Learning objectives

  • To choose how to improve a game by using variables
  • I can decide where in a program to change a variable
  • I can make use of an event in a program to set a variable
  • I can recognise that the value of a variable can be used by a program
