In this activity, students are provided with a list of supplies that survived their plane's crash in the Amazon jungle. They will organize the supplies to classify which items are useful for surviving in the Amazon. Students will use estimation and basic math skills to determine how much they can carry and to decide on what items to bring with them to survive in the Amazon until they reach their destination.

This website provides a collection of submitted puzzles for math students and their teachers. For each puzzle, students work to determine how each of the numbers, shapes, or graphs & equations are unlike the other three in the puzzle. There are many different, correct ways of choosing which one doesn't belong, and no answer keys are provided.
