Solved examples: Ordering three numbers (least to greatest) for Grade 1 students

🔢 Quick Study Guide

• 🌱 When ordering numbers, we want to arrange them from the smallest to the biggest.
• 🍎 Think of it like climbing stairs: you start at the bottom (smallest number) and go up to the top (biggest number).
• 💡 Look closely at each number. Which one is the tiniest? That's your first number! Then find the next smallest, and so on.
• ✏️ If two numbers are the same, just put them next to each other!
