This is a very handy collection of the top 50 high frequency verbs in French. This is set up so you can print out each verb on a regular 8.5 X 11 inch sheet of paper in color. One side has the verb with it's English translations in the past (mostly the passé composé, but the verbs that are most commonly used in the imparfait are in the imparfait), present, and the simple future. I have also included the opposite of the verb. I have found that it helps students to work with verbs in pairs. On the other side there is an image to go with the verb.
This can be used as a reference when you want to focus on one to a few verbs at once. You can post the verb or verbs that you are using as a reference for you and your students.
You can also easily project this instead of printing them out.
