This is a good phonetics website because it organizes all the consonants and vowels in the phonetic alphabet by manner, place and voicing. For each phoneme there are three words that are provided with a model of the production of each phoneme and the corresponding words. In addition, an animation and a step by step description of how you produce each phoneme is described as well. I highly recommend this especially for your phonetics class and for future reference.
