This PowerPoint makes for an excellent colourful introduction to German and its alphabet. It contains 37 slides, each of which have a picture and word which starts with the letter. I have also included some pronunciation sounds for English speakers to help them pronounce the letters when they are isolated (see the thumbnails).
Also included are the umlaut letters and the phonemes: Au, Ei, Eu, Pf, Sch, Sp, and St.
This PowerPoint also looks well when printed on A3 pages and hung up as posters around the classroom.
