If you get the HIG for Singapore, there are games and such that they talk about in there that you can do to teach the concepts. I like Singapore because it is laid out logically and covers all the bases. It doesn't have as much practice until you buy the extra problems or intensive problems. But with the HIG (home instructor's guide), there are enough ideas for ways to teach the concepts that I haven't felt we've needed anything beyond the textbook and workbook.
