This is an activity that I created for the students to do their first day back after winter break, but I think it is a good activity for any January day as a filler. It uses ir + a + infinitive and other present tense verbs and has students think about how they would like to better themselves this year. (There is also a version without the date so that it can be filled in year after year) The instructions are as follows.
Instrucciones: Llena los espacios con palabras que expresan lo que quieres hacer y mejorar este año. Luego, piensa en algo especial que te gustaría lograr este año.
