Saber vs. Conocer Worksheet. This is a great short practice once students have been introduced to the differences between the verbs conocer and saber. There are 10 different fill in the blank sentences. Students not only have to choose the correct verb, but also make sure they conjugate it for the correct subject. There is a friendly reminder at the bottom of the page for students to read in order to remember when to use the verb saber and when to use the verb conocer.
