A great resource for new Spanish students, this sheet lists common verbs with their English equivalent by category (ending, stem change, irregularity, etc). It also has charts with ar/er/ir endings and extra hints regarding some verbs.
Use it as a game: students form pairs and roll a dice, working their way through the verbs. If they roll a 1, they conjugate the 'yo' form. A 2 means conjugate the 'tú' form. Their partner checks and verifies if they earn points for correct answers. Variation: a right answer earns the number shown on the die, or the number next to the verb.
