Start by telling them a little about a famous expedition, for example, the first summiting of Mount Everest. (If you're more familiar with a different expedition you can use that.) If you do Everest you can print out the pictures and hold them up as you tell the story. "Did you know the tallest mountain in the world is in China? What is it? [try to elicit] Yes, it's Mount Everest. For a long time, people wanted to get to the top. No one could get to the top. Finally, a man from New Zealand, Edmund Hillary, tried to climb the mountain. It was dangerous and challenging, but Edmund Hillary was a brave explorer, and finally he made it to the top."

Go through the slides, tell the narrative and pause to elicit each vocab word and drill. Last slides (asking which is the braver expeditioner, etc.) are a lead-in to the next activity.

USE CUT-UP + MAGNETS: First demo - put up a sentence, e.g. "Which is more difficult?" and two options, e.g. "Doing homework" and "Fighting a bear." Kids talk about this briefly in pairs and tell each other what they think. Then choose a kid, or group of kids, to come up and make the next question. They form a sentence from the fragments (it must be grammatically correct!) and pick two pictures (if comparative) or more (if superlative). After, students talk in pairs about the question. Note - the "ier" and "iest" should be pinned to the board so that they cover up the "y" on the words "easy" and "scary."

USE PLANNER: Students plan an expedition (in small groups). Each group gets a worksheet. Demo this on board or with slides. First they decide where they are going. Then they decide who they want on their team. Answers can include superlatives, e.g. the smartest doctor, or the bravest wrestler. Lastly they write a few sentences about how they will prepare. If time, they can come up and tell the class about their expedition.
