Here's another quick place value activity for a math station.
You need a numbered spinner, place value blocks, paper, and pencil.
Students spin the spinner three times to make a number. They use the place value blocks to model the number. Once they have made a model of the number, they draw it in a graphic organizer and add the standard, word, and expanded forms of the number. You can use the example I included or let students come up with their own way to record the info. This would also be a good activity to show understanding of different ways of representing numbers in a math journal.
