Probability- May, Might, Could: ESL Lesson Plan
Attribution Non-commercial NoDerivative
In our introductory Verbs-Modals probability lesson we begin by introducing the concept of possibility (i.e. might/may if less certain and is if certain). We then quantify the concept of certainty with probability (i.e. we use may/might when we are 0-50% certain). We then introduce the negative form of may/might and finalize the lesson by introducing could for present and future possibilities (be careful here to make the distinction between could used as a Modal Verb and could used as the past tense of can).
