Patterns and repeats
Lesson details
Learning outcome
I can describe repetition.
Key learning points
- Repetition can be seen in everyday tasks.
- Sequences have patterns which repeat.
- Count-controlled loops are used to produce specific outcomes.
Keywords
Pattern - a design or sequence that repeats
Repeat - something that happens multiple times
Count-controlled loop - a chunk of code that repeatedly runs a section of the program a certain number of times
Common misconception
Repetition is only about numbers and how they are repeated.
Repetition means any repeated action, not just counting (e.g., brushing both sides of your teeth).
Teacher tip
Repeating commands are called �loops�. Loops can be repeated indefinitely, or a set number of times - the latter are called �count-controlled loops�, and will be used in this lesson. Use examples such as repeated moves in dance routines to illustrate repetition a set number of times.
Equipment
Pupils need access to a device with software that can execute Logo programs. Examples in this lesson use FMSLogo https://oak.link/fms-logo

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.
