Today the kids were presented with the concept of exponents and powers of 10. To introduce this, I asked them about the biggest and smallest objects in the world. To help them realize that the world is much bigger (and much smaller) than we imagine, I showed the following website. There are lots of different ideas, concepts, and interest points to explore from this. However, we soon realized that instead of writing a number with 20 zeros, it's just easier to use powers of 10.
