Online Rounding Quiz: 3-Digit Numbers to Nearest Ten

📚 Quick Study Guide

• 🔢 Identify the Tens Place: Find the digit in the tens place.
• 👀 Look to the Right: Check the digit immediately to the right of the tens place (the ones place).
• ⚖️ Rounding Rule: If the ones digit is 5 or more, round the tens digit up. If it's 4 or less, keep the tens digit the same.
• ➕ Rounding Up: When rounding up, add 1 to the tens digit. If the tens digit is 9, it becomes 0 and you add 1 to the hundreds digit.
• ➡️ Zero Out: Change the ones digit to 0.
• ✅ Example: Round 346 to the nearest ten. The ones digit is 6, so we round up. 346 rounded to the nearest ten is 350.
