Using Pictures to Explain Number Comparisons

Illustrative MathematicsVaries

The purpose of this task is for students to compare three-digit numbers and explain the comparisons based on the meaning of the hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons. It is important that students not only understand the correct symbol, but that they also understand the words that match the symbols. The first comparison is between 99 and 100, which is important for two reasons. Understanding this comparison is the key to understanding the rule for comparing three digit numbers depends on understanding that the largest possible two-digit number is less than the smallest possible 3-digit number.
