Here are some more ideas to use in your Spanish class! All projects are aligned with the ACTFL proficiency guidelines for the intermediate and advanced levels. These projects assess students' ablities to narrate and describe in the present and past tense. You can find the guidelines here: http://www.actfl.org/sites/default/files/pdfs/public/ACTFLProficiencyGuidelines2012_FINAL.pdf.
You can find an assessment grid here:http://www.ncssfl.org/LinguaFolio/LFrevisedgrid-October2009.pdf
To complete the entire assignment, it usually takes my 7th graders about 5 class periods (45 mins each).
For full credit, I expect my students to meet the Intermediate Low level in all areas (speaking, reading, writing, reading) but you could easily modify this project to meet your needs.
