I love anagrams! They make a great warm-up especially after a long break. You can write a phrase in the target language (like Feliz Año Nuevo) and have students make up as many words as they can. They should not use the three words given; however, they can use as few or as many letters as they can. Once you have given them the allotted time, you can figure out who came up with the most letters and who came up with the longest word. You can use a seasonal phrase or a phrase from their vocabulary list.
