Instead of steal the bacon, we would have several objects and call out one of them in Spanish. If you're thinking about anything else, feel free to ask. Yes, We've used Powerglide for children. My kids like it, but it is very expensive. Powerglide for Children has 4 cassette tapes, a teachrs book, and a student workbook that has the storyline written in it, along with some illustrations.
Kids follow along in their workbook as the cassette is played.
The material is presented in a very interesting way for children. I think it would be best after a child is reading, so that they can follow along better, but my 5 yr. Powerglide interweaves Spanish words with an English story line. It also has rebus stories and some other interesting variations. I am not sure that the speakers are natives, and there is at least one mistake in the written part.
