Rounding Tens to Thousands

Lesson 1

Problem:

Round the numbers to the nearest tens - 36

Solution Step 1:

When you are rounding you are converting a number into an easier number to work with. When rounding always ask yourself if the number is 5 or more you increase the number to the left by one and drop all numbers to the right to zero. Here are some examples:

Solution Step 2:

Round 26 to the nearest ten. Look at the number to the right of the tens (6). If the number is 5 or more, then the numbers to be rounded increases by one and all numbers to the right become zero.

Solution Step 3:

The number to the right of the tens is 6 the tens increases by one. The 2 becomes a 3 and the 6 becomes zero. 26 rounded to the nearest ten is 30.

Solution Step 4:

Round 24 to the nearest ten. The number to the right of the tens is 4, this number becomes zero. Since 4 is less than 5 the tens digit remains the same 2 and the 4 becomes zero. 24 rounded to the nearest ten is 20 Than 36 must be rounded to 40 40 is the answer.

Try two practice problems:	(A)    633 Round the numbers to the nearest tens
	(B)    176 Round the numbers to the nearest tens
