Year 7 – Lesson 2 – Sequence and variables

proumb18+在线观看 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

  • Define a variable as a name that refers to data being stored by the computer
  • 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
