This is a great worksheet to be used in class, as homework, or as a sub plan. Students start by looking up vocabulary related to the subsequent reading about the Galapagos. From there they read a brief explanation of regular present-tense verbs, and then complete a few small grammatical exercises. They then read a short passage about the Galapagos, answer comprehension questions (in English), and finally are asked to use regular present-tense verbs to write a brief explanation of a hypothetical trip to the islands.
This is a great resource that challenges students by testing multiple competencies.
