Check out Rod & Staff Spelling. We are using it this year for third grade and love it! There are usually 16 new words listed each week with three "review words". The lessons are divided up into three parts (A, B and C). You can do one section a day or spread the written work out over three days with a fourth day for review and test on the fifth day.
Section A is usually a vocabulary type exercise with the spelling list... fill in the blank. Section B is phonics (write the spelling word with /o/ spelled aw type questions. Part C is usually some sort of alphabetical work... listing the words in alphabetical order.
My DD likes to do all three sections on Monday, review orally (a la' spelling bee) and then take her written test on Thursday.
It's a versatile program, I like the vocabulary review and is pick up and go for me... NO prep work required. Plus, the words really seem to be sticking so it's working!! It's also really inexpensive. I have the TM and use it so I would definitely by both that and the student workbook.
