Students learning the IPA in English will find this page useful. Not only does it give the consonant and vowel charts, but it also gives example words for each vowel http://www.ic.arizona.edu/~lsp/IPA/SSAE.html
They may also appreciate the information given in this website, which allows you to download a guide to the learning the IPA: http://www.slideshare.net/englishbanana/focus-on-the-international-phonetic-alphabet-ipa
And this slide show (from Ohio State) provides a good overview of why we have three major areas of phonetics (Acoustics, Articulatory, and Auditory): http://www.mansfield.ohio-state.edu/faculty/dlindsey/Psych310/P310M5.pdf
Those students are interested in the naming conventions for these symbols, may want to check out the Wikipediat page on this topic, which (at the time of this post) is good, but could be more complete: http://en.wikipedia.org/wiki/Naming_conventions_of_the_International_Phonetic_Alphabet
And, of course, be sure to check out the other links we have on the LingEducator Phonetics/Phonology page.
Thanks to everybody who has been posting these wonderful resources online, you and/or your students should have a much easier time learning the IPA.
