Describe the value of a digit based on its place in the number. Read, write (in standard and expanded form), represent, compare, and order multi-digit numbers.

Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meanings of the digits in each place, using >, =, and < symbols.

Figure out if there are enough. Engage in a Number Talk to find "how many" and to answer a secret question. Play a fun "4 in a row" game with numbers and arrangements.
