This is a great worksheet that includes almost all of the irregular verbs.  Students have to first decode the past tense of the irregular verb.  The students are given numbers that they have to look up in a decoder bar and then they have to write the past tense of the verb down. After that, they match it to the pictures on the other page of the worksheet.  The verbs practiced include, sing, break, say, go, eat, win, and several others.  All together it goes over about 54 irregular verbs.  It is well organized and ready to go.  Another great material from Vanda Mata.
