Concept
When you have a lot of numbers in a table, rounding them can help you estimate totals quickly.
🎯 How to Round in a Table: 1. Look at the number in the first column. 2. Read the rule at the top of the next column. (e.g., "Round to nearest ten") 3. Apply the rounding rule and write the new number.
Example Table:
| Original Number | Nearest 10 | Nearest 100 |
|---|---|---|
| 342 | 340 | 300 |
| 185 | 190 | 200 |
| 45 | 50 | 0 |
Notice how rounding to the nearest hundred for 45 gives you 0, because 45 is closer to 0 than 100!
