For example, children classify objects (stacking blocks by shape or sorting them by color);
measure things («This
cloth isn't big enough to cover the table»); count just about anything (coins, candy, people, toys, and so on); transform objects (stretching dough and making a flat circular shape); recognize patterns and shapes (building a symmetrical structure by putting a two unit block
over two blocks); and explore spatial relations (finding a location or following directions).
