Teachers, I use this powerpoint as a guide for my 6th grade exploratory students. They only have between 7-10 lessons with me before they try out the other languages offered at my school. This powerpoint includes the alphabet, basic greetings & goodbyes, numbers 0-20, colors, gender explanation, and some links for games and review sites, like Quia.com
Please note: I choose to include the letters "CH" "LL" ñ" and "RR" in my alphabet slides. I know that all except the ñ have since been removed from the alphabet, however, I introduce them and make this point to my students! You can easily delete these letters if you choose.
I also have a PDF version of this powerpoint if you are interested in that!
