In this article, we overview the research literature exploring the teaching of evaluative language in written and/or visual texts in the elementary years of schooling. We then review the recently redrafted Australian Curriculum: English to identify the emphasis given to the teaching of evaluative language and the grammar of visual design across the elementary years of schooling in Australia. Also featured is the importance of the persuasive genre, and multimodal texts. The focus of our research work is on one Year 4 elementary years school teacher who scaffolds her students to bring all of this knowledge together to read/view and write/create in ways that take seriously the powerful written and visual language use of persuasive multimodal texts. The students are undertaking an inquiry topic “Sharks: Dangerous or Misunderstood?”. As part of the unit, students are exploring the written and visual grammar of danger signs. The students explore these texts by making a danger sign they would expect to see at the beach, as well as a danger sign for something that is not typically dangerous such as a ladybug. We examine the students’ use of the grammar of appraisal and the grammar of visual design, and their capacity to discuss the knowledge/power relationship of their own persuasive multimodal texts during an interview with their teacher.
