When introducing new grammar, I like to give my students worksheets that have a reference chart or notes at the top of the page to help build their confidence.
This worksheet includes a chart of the "yo" conjugations, along with the infinitive and definition for the following verbs;
salir, venir, poner, dar, hacer, saber, ver, caer, traer, decir and oír. There is a simple conjugation practice activity followed by a series of questions that focus on the infinitives in the chart. Great way to review question words at the same time!
