You have great ideas already. More ideas:
*Jeopardy games to review material- If you have a projection system, you can use some of these websites:

Lots of premade PowerPoints- including Jeopardy

If you do not have that technology, you can still play a game using the chalkboard as the screen.
*Poetry reading- we are practicing reading poetry in different ways (set to a beat, choral reading, partner reading, adding actions, etc.). Then, students are picking a poem and reading it on their own or with a partner. Great for poetry appreciation and fluency! I am also adding a poetry notebook of poems they have written as their "ticket" into the reading.
*Take a field trip to a park for lunch and to write some science observations.
*Math games- check out Marilyn Burns' books.
*Hands on science experiments- lots of websites available.
