How to use the decimal practice
- Pick a skill. If you are not sure, start with Place value and move right along the row as each one gets easy.
- Answer each question. Type decimals with a point. On a phone, a number pad with a point key appears below.
- Read the hint when an answer is wrong. It shows the method: lining up the points, counting decimal places or moving the digits.
- Check the stars. 8 or more out of 10 means the skill is secure. The results list the questions to practice again.
How answers are marked
A decimal can be written in more than one way, so the marking accepts every form of the right number. For example, 0.5, .5 and 0.50 are all correct for one half. Trailing zeros don’t change a decimal’s value, and the hint shows the usual way to write it.
Questions that ask for a fraction have two boxes, top and bottom, and any equivalent fraction counts. Rounding questions need the rounded value: 3.46 rounded to the nearest tenth must be 3.5.
A sensible order for decimal practice
Decimals build on place value. Children who understand that 0.3 means 3 tenths make far fewer mistakes when they line up the points to add. This order follows the US Common Core and the NCERT books:
- Tenths and hundredths (grade 4): shaded grids and money. Start at the decimals hub.
- Reading, writing and the number line (grades 4–5).
- Comparing, ordering and rounding (grades 4–5): use the place value chart to see each digit’s value.
- Adding and subtracting (grades 4–5), then × and ÷ by 10, 100 and 1,000 (grade 5).
- Multiplying and dividing (grades 5–6), with the decimal calculator to check the steps.
When a decimal skill won’t stick
- “Longer is bigger”: thinking 0.45 is more than 0.5. Add a zero so both have two places: 0.45 and 0.50. Now compare.
- Not lining up the points when adding: 3.5 + 1.25 written as 3.5 over 1.25 lined up on the right. Write the points under each other first.
- Losing the point when multiplying: count the decimal places in the question; the answer has the same total.
- Moving the point the wrong way when dividing by 10. Dividing makes a number smaller, so the digits move right.
The decimals hub has a lesson for every skill, with pictures and a script for parents.
A 10-minute routine
- Minutes 1–2: say three prices aloud as decimals, like $4.05 and $4.50.
- Minutes 3–8: one round of 10 questions on the current skill.
- Minutes 9–10: read the hints for anything missed and try one again on paper.
For parents and teachers in the classroom
- Share a skill: add ?skill=place, read, line, comp, round, addsub, pow10, mult, div, frac or money to the address.
- Projector friendly: large numbers and an on-screen number pad work well for a whole-class warm-up.
- Private by design: no account and nothing stored online.

Questions parents ask
How can my child practice decimals online for free?
Use the practice tool at the top of this page. Pick a skill, such as place value or adding decimals, and answer 10 questions one at a time. Every answer is marked straight away, with a hint when it is wrong.
How do I type a decimal answer?
Type it with a decimal point, like 3.75. On a phone or tablet, the number pad below the question has a point key. Answers like 0.5, .5 and 0.50 are all marked right.
Which decimal skill should my child start with?
Start with Place value and Read & write, then Number line and Compare & order. Rounding, adding and subtracting come next, then multiplying and dividing.
What grade are these decimal questions for?
Grades 4 to 6 (classes 4 to 6). Tenths and hundredths suit grade 4. Thousandths, rounding, adding, subtracting and × 10 suit grade 5. Multiplying and dividing decimals suit grades 5 and 6.
Do the questions repeat?
No. Every round makes new random questions, so the same skill can be practiced again and again.
Can teachers use this decimal practice in class?
Yes. Link to a skill with ?skill= at the end of the address, for example /decimals/practice/?skill=round. Every child gets their own random questions, and nothing needs a login.
