Objective: Students work with 6-digit numbers, locating them on number lines between consecutive tens, hundreds, thousands, 10-thousands, and 100-thousands, identifying endpoints and midpoints, rounding numbers to any place, and comparing the accuracy of rounding to different places.
- What are some situations in real life where someone might need to round 100-thousands?
- What does accuracy mean? Why is accuracy important?
- Why might a number rounded to the nearest 100-thousand be less accurate than the same number rounded to the nearest thousand or 10-thousand?
