I recall sitting in my 7th grade English classroom. My teacher placed a document (similar to the one here) on the overhead and for 2 days straight, we sat copying each verb and its various verb tenses/forms. The rote learning of grammar. Memorization. Practice. Drill. And it worked! As they find in math, there are benefits of rote memorization. For an ESL student, learning verb forms and tenses can be confusing. But if they understand the various forms, how they are used in each sentence and KNOW what is required (or at minimum can consult a cheat sheet), it is a much less grueling task--for both the student and the teacher alike.
It is important to understand that first, students must understand there are various forms of verbs, and how they appear in sentences, therefore pair this item with my "What is a Verb" handout. Students should also be familiar with "color coding". Note that VERB color coding is a completely different task than sentence color coding, don't allow them to be confused.
This item can be used as a reference, or rote drill/memorization tool (which I find most beneficial when students to the work themselves, then keep it for reference). I have also, in the past copied these to a 3X5 index card for a ring reference tool for older students. There is a blank page which can be used to continue adding new verbs as they come up. Note also, this is a IRREGULAR Verbs reference. For REGULAR Verbs, see "Regular Verbs (Color Coded)".
