I've been going through Syntorial[1] which is an interactive synth tutorial. I'm about half-way through and I've found it very useful for understanding not just what each part of a synthesizer does to the sound, but how it changes the sound. Later on, as you learn multiple functions of the synth, you practice combining them to recreate sounds.

The software itself is a bit pricey and only runs on Mac or Windows but I've found it very helpful for getting an intuitive sense of what the different synth options actually change.
