How to learn decimals, in order
Decimals are place value extended past the ones, so Comparing Decimals comes first to build the sense that 0.5 is bigger than 0.45. Then Rounding, Adding & Subtracting (where lining up the decimal point is everything), and finally Multiplying Decimals, where you count decimal places to place the point.
Decimals by grade
- Grades 4–5: comparing and rounding decimals.
- Grade 5: adding and subtracting decimals.
- Grades 5–6: multiplying decimals.
Common mistakes, and how to help
The classic error is thinking more digits means a bigger number (believing 0.45 > 0.5). Lining decimals up by place value clears it up. In addition, the fix is always line up the decimal points, not the right-hand ends; in multiplication, count the total decimal places in both factors to place the point.

Frequently asked questions
Is the decimals practice free?
Yes — all practice and worksheets are free, no sign-up, and no ads inside the practice.
How are decimals related to place value?
They extend place value to the right of the ones — tenths, hundredths, thousandths — each ten times smaller than the place before.
Why is 0.5 bigger than 0.45?
Because 0.5 is five tenths and 0.45 is four tenths plus five hundredths. Comparing by place value, not digit count, gives the right answer.
How do you add decimals?
Line up the decimal points (and the place columns), then add as usual, keeping the point in the same place in the answer.
How do you place the point when multiplying decimals?
Count the total number of decimal places in both numbers, then put that many in the answer.
Can I print decimals worksheets?
Yes — each skill page has a print button for a fresh 20-question sheet with an answer key.
