Thanks for visiting the decimals and percents worksheets page at Math-Drills.Com. On this page, you will find a variety of worksheets that will help students reinforce the skills they are learning related to decimals. To start, you may find the blackline masters below to be helpful in teaching the concepts of decimals and place value. Rounding, comparing and ordering decimals worksheets allow students to gain more comfort with decimals before they move on to performing operations with decimals. At the end of the page, you will find decimal numbers used in order of operations questions.

Black Line Masters

The thousandths grid is a useful tool in representing operations with decimals. Each small rectangle represents a thousandth. Each square represents a hundredth. Each row or column represents a tenth. The entire grid represents one whole. The hundredths grid can be used to model percents or decimals. The decimal place value chart is a tool used with students who are first learning place value related to decimals or for those students who have difficulty with place value when working with decimals.

Decimals Worksheets -- Rounding

The convention on the decimals worksheets below is to round up on a five. Apply rounding knowledge to estimate answers on the operational worksheets that follow.

Comparing Decimals Worksheets

Use the decimals worksheets below to help students recognize ordinality in decimal numbers.

Ordering Decimals Worksheets

The decimals worksheets below help students compare numbers further by ordering lists of decimal numbers.

Percents Worksheets

Percents are a special kind of decimal. Once the connection is seen between the two (a percent is just 100 times a decimal), they are not so mysterious. Percents have a few specific applications that we've highlighted in the worksheets below.

Vertical Operations with Decimals Worksheets

Adding and subtracting decimals is faily straightforward when all the decimals are lined up. Use these worksheets to ensure students understand where the decimal is placed when adding numbers. A wonderful strategy for placing the decimal is to use estimation. For example if the question is 49.2 + 20.1, the answer without the decimal is 693. Estimate by rounding 49.2 to 50 and 20.1 to 20. 50 + 20 = 70. The decimal in 693 must be placed between the 9 and the 3 as in 69.3 to make the number close to the estimate of 70.

Decimals Worksheets -- Addition

Try the following mental addition strategy for decimals. Begin by ignoring the decimals in the addition question. Add the numbers as if they were whole numbers. For example, 3.25 + 4.98 could be viewed as 325 + 498 = 823. Use an estimate to decide where to place the decimal. In the example, 3.25 + 4.98 is approximately 3 + 5 = 8, so the decimal in the sum must go between the 8 and the 2 (i.e. 8.23)

Decimals Worksheets -- Subtraction

Have you thought about using base ten blocks for decimal subtraction? Just redefine the blocks, so the big block is a one, the flat is a tenth, the rod is a hundredth and the little cube is a thousandth. Model and subtract decimals using base ten blocks, so students can "see" how decimals really work.
