“High-quality direct teaching is oral, interactive and lively. It is not achieved by adopting a simplistic formula of ‘drill and practice’, or by expecting pupils to teach themselves from books. It is a two-way process in which pupils are expected to play an active part by answering questions, contributing points to discussions, and explaining and demonstrating their methods to the class.”
(From the Primary Framework for Mathematics.)
The importance of this kind of work is clearly stated above. Don’t just give this maths worksheet to your child, go through it with them, help them use the language of maths to secure their recall, thinking and reasoning skills.
