Descriptosaurus Grammar Companion Ages 9 to 12 is a flexible grammar toolkit based on current research about effective strategies for teaching grammar tools and sentence construction (investigation, imitation, combining and expansion). It includes guidelines, exercises, scaffolds and models, and by showing a clear progression route to the acquisition and consolidation of increasingly more complex grammar tools it provides teachers and students with a road map that makes learning about sentence construction and revision visible. This book is a collection of connected resources that can be used as and when required and it provides an easily accessible differentiation resource for each student based on their current stage of development, not the age-related targets and expectations. It enables the learning process for grammar tools to be recursive rather than linear; to be regularly revisited in short bursts to consolidate students’ knowledge and usage, or to correct any misconceptions or problem areas without impeding any writing activities already planned. Chapters focus on four main points:InvestigationImitationCombiningExpansionThis Grammar Companion supports the main Descriptosaurus book and scaffolds students in their journey through the world of language. This essential resource will strengthen their language muscles and build confidence with sentence manipulation when revising their own texts, thus freeing their minds to think about the important issues of writing: content, audience and purpose, and organisation and structure.
