4th Grade Math › Number & Operations in Base Ten
Round to the nearest ten.
When we round a number to the nearest ten we look to the ones place to tell us if we round up or down.
If the number in our ones place is or greater, we round up. If the number in the ones place is
or less, we round down. When we round up, the number in the tens place increases by
and all the other numbers to the right become
. When we round down, the number in the tens place stays the same and all the other numbers to the right become
.
In this case, is greater than
so our rounded number is
Solve by making a rectangular array.
Using our problem to make a rectangular array, we know that we are going to use a total of squares, and one dimension of the rectangular array is going to have
squares, we'll make that the width. Our answer will be how many squares high the rectangle array is, or the height.
We can start with squares and keep adding
on top of the previous
until we've used all
squares. Our rectangular array is
squares high with
squares left over, which is our remainder.
