When you 'Start', you will see a verb. Hidden in the grid below are the past and past participle forms of the verb. Can you find them? The words go up, down, sideways and even backwards (sdrawkcab)! When you have clicked on a letter that is part of a word you need it will go green. If you click on a letter you don't need, it will go red. Do the past tense first and then the past participle.
(Remember, even if a letter is green because you clicked on it as part of the past tense, you still need to click it again to complete the past participle!)
