🎢 The Rounding Rollercoaster! 🎢

he core objective is to teach students a consistent strategy to round whole numbers to the nearest ten, hundred, or thousand. Students learn the key rules—the "4 or Less? Let it Rest!" rule and the "5 or More? Raise the Score!" rule—by focusing on the helper digit immediately to the right of the rounding place. This process simplifies large numbers for quick calculations and helps students check the reasonableness of their answers. The lesson aligns with Texas Essential Knowledge and Skills (TEKS) standard 4.2(D).
