What you’ll learn

  1. Bigger and SmallerCompare two objects and say which is bigger and which is smaller, then sort things by size.Comparing means looking at two things to see how they are different. A beach ball is bigger than a tennis ball; a tennis ball is smaller. Big things (a bus, a tree) and small things (a key, an ant) can be sorted into groups.
  2. More and FewerCompare amounts using the words more and fewer, and order groups from fewest to most.When there are lots we say more; when there are just a few we say fewer. A plate of 5 apples has more than a plate of 2. Groups can be put in order from fewest to most, with the smallest group first and the biggest group last.
  3. Taller, Shorter, LongerCompare heights using tall and short, and order objects from shortest to tallest.Tall things reach up high, like a giraffe; short things are low, like a mouse. When we line things up from shortest to tallest, the shortest goes first and the tallest goes last. Comparing sizes and amounts helps us make sense of the world.
