Test your skills: Order numbers from smallest to largest (up to 20)

📚 Quick Study Guide

• 🔢 What does ordering numbers mean? It means arranging numbers from the smallest to the largest.
• 📏 Comparing Numbers: Start by looking at the numbers. If one number has fewer digits, it's smaller. For example, 5 is smaller than 12.
• 🧮 Numbers with the same number of digits: If the numbers have the same number of digits, compare the leftmost digits first. For example, to compare 12 and 15, look at the '1' in both numbers; they are the same. Then, compare the next digits: '2' and '5'. Since 2 is less than 5, 12 is less than 15.
• ➕ Using a Number Line: Imagine a number line. Numbers to the left are smaller, and numbers to the right are larger.
• 💡 Tips: If you're having trouble, try writing the numbers down in a column, aligning the digits. This makes it easier to compare them.
