What are the principles of counting?
The first three principles—stable order, one-to-one correspondence, and cardinality—are considered the “HOW” of counting. Research is clear that these are essential for building a strong and effective counting foundation. The remaining two principles—abstraction and order irrelevance—are the “WHAT” of counting.
