Year 7
Lesson 2 Sequence and variables
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.
