As I always tell my students, it is important to know all the irregular verbs by heart. It may sound a little bit difficult at the beginning but there are a lot of fun games and activities on the Internet to help you memorize them. I have selected some games for you to practice.

• Verbbusters. In this web page you can test your knowledge of irregular verbs and even competing with other users. You can select your level to adjust the questions.
• The frog verbs game I & II. This exercise is quite entertaining. You have to get the frog across the pond by choosing the right lily for him to jump on to. If you click on the lily with the correct past tense form of the verb, the frog will jump there. If you click on the wrong lily, the lily will sink, and the snake will eat the frog.
