In this section we are looking at what most would consider deep place values. Finding the value of sums that only include tenths and hundredths values are enough of a task for students. When you extend that one more value, they often get lost and get frustrated easily. The best advice that we can give is to make sure that the problems you are working with are written large enough that you can clearer make out each place value. It is often helpful to note each place value and how it changes throughout the problem. The most common error that we come across is the position of the decimal point. This is where right-justifying your whole numbers and left-justifying your decimal values can come in handy. This really tells you where the decimal place should end up. The best habit to get into is to make sure that your do not ignore the placement of the decimal.

These worksheets show the problems as vertical addition. This really helps students get a handle on where each place holder is located. We would even recommend that you have your students take it even a step further and have them label the: tenths, hundredths, and thousandths places. The introduction or review sheet can be found at the bottom of this page. Numbers may contain either four or five digits, including those after the decimal. These worksheets explain how to add decimals to the thousandths. They include problems with addends having both single and double digits and decimals are to the thousandths.
