There's no need to spend time creating a resource to explain the difference between proper, common, abstract, collective and concrete nouns. We've got you covered with this Year 3 Using Different Types of Nouns Teaching PowerPoint. It recaps the differences between them, gives examples of how to use them in sentences and allows children to apply their knowledge with a range of question styles.
Use this as your main teaching resource during your lesson input to guide children step-by-step through this grammatical concept. Alternatively, you could pick and choose which section to focus on based on the needs of your class. This resource is also suitable for home learning and can be used in an intervention group. There's no end of uses, so get it downloaded!
