Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.
These resources were created for remote use during the pandemic and are not designed for classroom teaching.
Lesson details
Key learning points
- Static data structures reserve memory locations for a set amount of data. Their size cannot change.
- Dynamic data structures are more flexible. The memory capacity is not fixed.
- The choice() function can be used to randomly choose an item from a list.
- For example, it could randomly pick a pixel from a list storing all pixels in an LED matrix.
Keywords
Append - add to an existing data structure
Pixel - a single element of an image on a computer screen
Common misconception
A list is static, so once it is created it cannot be edited or amended.
A list is a dynamic data structure that can change in size. The append() function can be used to add elements to a list.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.

Equipment
All pupils require access to the Raspberry Pi Code Editor. Pupils could use the physical components of a Raspberry Pi computer and a Sense HAT for this lesson, but they are not essential.
