Help feed the viper by recognizing correct subject/verb agreement. Instructions >>>
Gameplay - Recognize subject/verb agreement (I am, he is) by matching the subject that appears above the viper with the incoming verbs. To eat a verb, press the space bar or click when the word is in the strike zone. The verb must agree in tense and number (singular or plural) with the subject and be a correct verb form (ran instead of runned). Each correct verb that you eat and each incorrect verb that you do not eat will count as a hit. Conversely, each correct verb that you do not eat and each incorrect verb that you eat will count as a miss. Each stage lasts one minute.
Options - There are four different versions you can choose to play that will have you looking for different verb tenses: to be and have, present tense, past tense and past participle. You may also choose to play slow, normal or fast.
