Rounding:

When rounding, check the number to the place you are rounding to (for example when you are

rounding to the thousands place, look at the digit in the hundreds place), and if it is less than 5, the

place stays the same, and there are zeroes after it. If it is 5 or greater, add one to the place, and then

there are zeroes after that place.

1. Round 12,678 to the nearest thousand.___________________________________

2. Round 25,435 to the nearest hundred.___________________________________

3. Use rounding to estimate 7,831+2,438a. 9,000b. 10,000c. 8,000d. 11,000

Front-end Estimation With adjustment:

Sample problem: 4,589+2,438

4,589 + 2,438 Take the front numbers and place zeroes after them

4,000+2,000=6,000

589+ 438 Then take what is left and round them to the nearest hundred

600+400=1,000 Round this answer to the nearest thousand. If it is less than 500, it becomes zero

6,000+1,000=7,000 Add (or subtract) the two together to get your answer

1. Use front-end estimation to solve 6,450+2,890


3/4

5689 First, look at the numbers in the hundreds and thousands place.

6 12 18 24 30 36 42 48 54 60 Then skip count the 6's (or whatever number you are dividing by) and

find the two numbers that are around the digits you pulled from before

5400 Find which one the digits are closest to, then add zeroes to replace the tens and ones digits

54006=900 Then divide
