Year 7 – Lesson 2 – Sequence and variables

Curriculum KS3 Unit Lesson

In this lesson the learners will be introduced to variables as well as the opportunity to get more confident with sequences. The lesson will start with a story that includes variables; learners have to replace the variable names with the values they refer to when they reach the relevant places in the story. Learners will then be given a Scratch program where they will work in pairs to predict, run, investigate, and modify. The lesson will conclude with an activity requiring the learners to trace the value of a variable in an algorithm.

Learning objectives

  • Recognise that computers follow the control flow of input/process/output
  • Predict the outcome of a simple sequence that includes variables
  • Trace the values of variables within a sequence
  • Make a sequence that includes a variable
