I saw this idea over at Shari Sloane's site, Kidscount1234. I changed mine a bit because I prefer my word work sheets to have little to no extra wording and I wanted to have some extra spaces for them to write in.
Basically put whatever words you want on the decorative gems like you can buy at the Dollar Tree. Put them in a gumball machine. The students get a 'gumball' out and write the word on their sheet.
