🔢 Topic Summary
Ordering numbers from least to greatest means arranging them from the smallest value to the largest value. Think of it like climbing stairs – you start on the lowest step and go up to the highest. When you have a set of numbers, look for the smallest one first, then the next smallest, and so on until you reach the biggest number. This skill helps us understand quantities and compare different amounts.
For first graders, this concept is usually introduced with numbers up to 20, but the same principle applies to larger numbers too. With practice, you'll become a pro at spotting the smallest and largest numbers in any group!
