This is a document with 35 fill-in-the-blank sentences - 20 sentences have regular -AR, -ER, and -IR verbs, and 15 have stem-changing. The stem-changing verbs are divided (e->ie, o->ue, e->i) and labeled. There are verb charts for regular -AR, -ER, and -IR verbs, and also for each type of stem-changing verb to help students out. I use this for my Spanish 1 students after we have finished all the verb types and with my Spanish 2 students as a review! An answer key is included. The zip file includes both an editable Word doc and a PDF.
