Second part of Series
This series starts with Pythagoras and progresses through Perimeter, Area, Surface Area, Volume and Capacity, before bringing these skills together in 3D problems. The lessons are structured to build students’ confidence step by step, starting with simple examples and gradually working towards more challenging questions.

Do the examples on the Worksheet
Try the examples yourself before looking at the memo. Don’t worry if you struggle or get some answers wrong — that’s part of learning! You’ll learn much more from making and correcting your own mistakes than simply looking at the answers.
