I am retired now but these are some of my favorite activities from when I taught third and fourth grade.
I used poetry for fluency practice. Any poem will work but my favorite were from books by Mary Ann Hobberman. They are all titled "You Read To Me, I'll Read To You. Each has a different theme. They are filled with poems for two voices and are all kid friendly and humorous. I would give the part of the first speaker to the better reader and the second speaker part to the slower reader. The first reader sets the pace and the second reader will naturally try and match their pace. I allowed students to practice each day of the week. I walked around and listened and advised. On Friday after practicing they read them aloud for a fluency grade. I used the attached rubric for grading.
I liked using fun poems to teach students about lines, stanzas and rhyme schemes. I modeled from the document camera and they each had a copy of the poem in front of them as well. I read the poem to them first. Then we choral read the poem together. Then I showed them how to number the lines on the left and the stanzas on the right. Once we had practiced that enough I helped them to find the rhyming words and we would underline them. We also discussed alliteration, similes, metaphors and personification. We circled and labeled these. I modeled, then guided and finally they could do this themselves. "Homework Oh Homework" by Jack Prelutsky is a perfect poem to start with for this project. The students alway like the subject matter of the poem. Then I began to model and teach them how to write about a poem using all this new vocabulary and poetry knowledge.
To teach visualization I used Jabberwocky by Lewis Carroll. The poem is filled with nonsense words so this activity also helps with context clues. I would read them the poem. We would discuss the strange made up words. Then I would give them a copy of the poem and I would read it again while they followed along. I told them to imagine what was going on in the poem while I read. I explained that they might not be able to find meaning in all the words but that was okay. Afterwards I gave them paper to use with their crayons and asked them to draw a scene from this narrative poem. I used privacy dividers so no one can see their drawing. I walked around and helped students who had difficulty getting started. Then we shared and discussed our pictures in connection with the poem. I had them number the lines and stanzas so they could refer to them when they explained their drawing. Finally I read them the book titled Jabberwocky by Graeme Base. This is an illustrated copy of Mr. Carroll's poem. We enjoy the drawings along with the poem and compare it to the student's drawings.
I also used websites like poetry4kids and giggle poetry for poetry practice.
