🔍 Understanding the Image
At the top, it says:
"Rounding Numbers To Nearest Ten-Thousands"
Below that is a number line from
0 to 9, with arrows pointing in two directions:
-
Numbers 0 to 4 → Point downward with the label
"ROUND DOWN"
-
Numbers 5 to 9 → Point upward with the label
"ROUND UP"
This represents the
rule for rounding based on the digit in the
thousands place when rounding to the nearest
ten-thousand.

✔ Example Walkthrough
Let’s say we want to round
46,789 to the nearest ten-thousand.
1. Identify the
ten-thousands place:
- The number is
46,789
- The digit in the
ten-thousands place is
4 (40,000)
- The digit in the
thousands place (next one) is
6
2. Now apply the rule:
- The thousands digit is
6, which is
≥ 5, so we
ROUND UP
3. So,
46,789 rounds up to
50,000

Another example:
32,450
