This lesson plan teaches first grade students about rhyming words using the book Goodnight Moon by Margaret Wise Brown. The students will identify rhyming words from the story by matching them on a chart. They will then play a matching game to practice identifying rhyming words. Follow up activities include copying rhyming words, drawing pictures, making sentences, and writing a new story using rhyming words. The objective is for students to identify and match rhyming words from a familiar text.
