This document describes three demonstrations using picture cards to teach students about comparing quantities: 1) The first demonstration teaches comparing more, showing that the second card has two more fish than the first card. 2) The second demonstration teaches comparing less, showing that the second card has one less fish than the first card. 3) The third demonstration teaches comparing "same as" and "not the same as", showing that while the pictures have different sized fish, they have the same number of fish.
