One of my kids favorite centers is write the room! I have made some Word Detective sheets for them to use. They have a “case file” with certain clues they have to look for. For example, write words that have the letter s, write words that have 4 letters, etc: Here’s one of the sheets from the pack.

You can make more on your own or you can download the entire pack along with the word dectective poster shown above from TPT for $4.
