This document outlines a 20 minute lesson plan on nouns for Year 4 students. The goal is for students to thoroughly explore and understand how to identify and use nouns. Objectives include students being able to use nouns correctly in writing, identify nouns in sentences, and categorize nouns as countable/uncountable or proper/common/collective. The lesson will use PowerPoint slides and a worksheet, and involve individual and group activities where students identify and categorize nouns. Students' understanding will be evaluated based on their ability to achieve the objectives.
