Students fill out a chart with saber and conocer (vosotros not included) and then have to complete 20 fill in the blanks with the correct form of either saber or conocer. The examples are straightforward and the sentences constructed of such grammar and vocabulary that the students should easily be able to recognize the meaning of the sentence and thereby be able to distinguish whether they should use saber or conocer. They then use the chart as reference to choose the correct form. Subject pronoun substitution is required for some of the questions.
