--"HOW TO ROUND TO ?"--
Example: "Round 4,346 to the nearest 10"
"To round to the nearest 10, we find the tens digit which is 4,346. We then look at the number to its right, which is the units digit 4,346. As it is 5 or above, we round up the tens digit to 5 and the units digit becomes zero, giving 4,350."
--TASK--
"In your books, complete this sentence for rounding up or down to the nearest 100. Be prepared to share!"
