1.37 Introduction to Bounds GCSE PowerPoint Lesson

This 35-slide lesson introduces pupils to the concept of bounds, focusing on identifying the possible range of values that a rounded number could represent. Students will explore numbers that have been rounded to the nearest whole numbers, integers, decimal places, and significant figures. Through a mix of straightforward calculations and real-life worded problems, pupils will practise working backwards to determine the original values that could have resulted in a given rounded figure. This lesson builds strong foundational understanding and is ideal as a prerequisite for more advanced work on error intervals and bounds in calculations.

Note this lesson does not include bound calculations. See bound calculations higher lessons for this resource.

The lesson includes:

• Clear, guided examples

• Discussion opportunities from Think, Pair, Share

• Mini whiteboard section to check understanding and clarify misconceptions
