Standard 4.NBT.2
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 to record the results of comparisons.
Explanation: We are using bigger numbers, up to the millions, and comparing them. We show students to start on the far left and compare each place. If the numbers are the same go to the next place, and as soon as they find a larger number, they are done.
