At either a special or typical meal, have your child make a list of the food and drink being consumed. Choose one item from the list, and collect word images to describe the food or drink. (For example, macaroni and cheese: hot, gooey, cheesy, creamy, yellow, etc.)
Next make a list of comparisons, such as creamier than pudding, gooier than mud, etc. From there, work on some similes: hot as an oven, crunchy like pretzels, and so on. Finally, you take all the images and comparisons and create a poem, beginning with descriptive words, moving into comparisons and similes, and coming back to the original idea.
Kids will have a lot of fun with this, and you can do the oral “composing” while you eat. Keep your poems and make a collection of food poetry that can be displayed in your kitchen.
