This introductory lesson serves a double purpose: it reconnects learners with Python, making sure they can read and create simple programs that use selection, and it also takes a step forward, providing a very gentle introduction to lists.
and use simple arithmetic expressions in assignment statements Use selection (**if-elif-else
This lesson introduces selection and randomness. These are two features that will allow learners to develop programs with a very diverse range of behaviours. Learners will revisit some of the programs that they have encountered in previous lessons and extend them into more versatile programs that use selection. They will develop a simple number guessing game, which will eventually include randomness.
Use relational operators to form logical expressions Use binary selection (if, else
Learners will follow instructions given to them and give instructions to others. They will consider the language used to give instructions, and how that language needs to be clear and precise. Learners will combine several instructions into a sequence that can then be issued to another learner to complete. They will then consider a clear and precise set of instructions in relation to an algorithm, and will think about how computers can only follow clear and unambiguous instructions.

Pupils will apply their understanding of the importance of order in programs. They will then use operands in selection to determine the flow of a program. Pupils will then modify a program which will enable the micro:bit to be used as a navigational device. To code this, they will adapt the code they completed to make a basic compass.

This lesson progresses to multi-branch selection, then introduces while, the general-purpose iterative structure available in Python. Learners will explore problems that will allow them to deepen their comprehension of when and how selection should be used. For example, they will build programs that check the weather conditions where they are living and display appropriate responses. They will also be introduced to iteration, making sure that they understand the mechanics of how it works, before they go on to build their own iterative programs in the next lesson.
