Finding equations of straight lines: y = mx + c loop cards
This engaging self-checking loop activity helps students master straight line equations through a clever series of interconnected cards that create a satisfying full-circle moment when completed correctly.
What's included
- 12 carefully sequenced cards featuring graphs of straight lines
- Student answer tracking sheet with space to record equations
- Full solutions for self-checking and easy marking

Using this resource in the classroom
Perfect for both KS3 and GCSE maths lessons, these loop cards work brilliantly as a starter activity to reinforce understanding or as a plenary to check learning. Students can work individually or in pairs, making it ideal for differentiated learning.
For KS3, focus on identifying positive gradients and y-intercepts. At GCSE, extend to include negative gradients and fractional coefficients. The self-checking nature of the activity means students get immediate feedback - if they don't end up back at their starting card, they know they need to review their work.
The activity typically takes 15-20 minutes, making it an excellent option for focused practice during revision sessions. For lower-ability students, consider providing a structured worksheet with gradient and y-intercept scaffolding. More able students can be challenged to explain their methods and justify their answers.
