Lesson details
Key learning points
- A table can be used to plot coordinates on Desmos.
- It is easy to see if any of the points do not fit the pattern.
- It is possible to draw a line through the points using Desmos.
- Using the line you can determine if points do or do not fit the rule.
Keywords
Arithmetic (linear) sequence - A sequence where the difference between successive terms is a constant.
Common misconception
When plotting the sequence $$3n-1$$ using technology you need to type each coordinate individually.
"We use technology to make things easier. There must be a quicker way!" Look for the 'table' function.

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.
