On Friday, we examined four tasks--we compared the mass of ants v. elephants, the mass of all the ants in the world v. all the humans in the world, the size of a giant sequoia tree compared to the size of its seed, and the height of a piece of paper if you folded it in half 60 times. All of these activities gave students practice comparing numbers and using scientific notation operations to help answer some challenging questions.
