2.30 Inequalities – Possible Integer Values & Number Lines GCSE PowerPoint Lesson

In this 35-slide lesson, students will be introduced to linear inequalities and learn how they differ from equations. They will practise interpreting inequality symbols (>, ≥, <, ≤) and stating the possible integer values that satisfy a given inequality. Students will also learn how to represent solutions visually by plotting them on a number line, using open and closed circles to show whether endpoints are included. This foundational lesson builds key skills needed for solving and graphing inequalities in future algebra topics. 

The lesson includes:

• Clear, guided examples

• Discussion opportunities from Think, Pair, Share

• Mini whiteboard section to check understanding and clarify misconceptions

• Two structured tasks to practise key skills

• Challenge activity to extend and deepen learning

Perfect for engaging learners while reinforcing essential algebra concepts.
