As a review, I showed the students posters of the different types of sentences. I found mine on Pintrest (where else?!) and they have cute little monsters on them with a definition and an example of each sentence type. Here's the link to the 4 Types of Sentences Monster Posters pin
We made a foldable to reinforce the 4 types of sentences. Each flap is cut on the solid line and the definition and an example goes behind the flap.
The original link can be found here: Types of Sentences Foldable
Then we do lots of practice identifying the sentence types - around the room, in our textbook, in magazines, in conversation, etc.
We ended our mini-unit by doing a Sentence Hunt. Each student became a detective and was tasked with hunting through a book to find an example of each type of sentence. It gave them real hands-on experience with the different types of sentences:
