💯 Decimals and Percentages for Kids: Free Games and Worksheets

Decimals and percentages for kids become much easier when children can see them. On this page you will find four free activities that start with tenths and hundredths on a grid, move on to comparing decimals, and then link fractions, decimals and percentages together before finding a percentage of an amount. Every activity works online on a phone, tablet or computer, and each one can also be printed as a worksheet for homework, maths centres or quiet practice at home.

What these decimals and percentages activities are

This module turns an abstract topic into something children can see, touch and talk about. Tenths on a Hundred Square lets learners shade parts of a 100-grid so they understand that 0.1 is one tenth and 0.01 is one hundredth of the whole. Which Decimal Is Bigger? asks children to compare two decimal numbers by lining up the digits and looking at place value, not at length. Fractions, Decimals and Percentages builds the three-way link that older primary pupils need: 1/2 = 0.5 = 50%. Percentages of Amounts finishes the journey by asking real questions, such as finding 25% of 80 or 10% of a price.

Each activity uses clear numbers, friendly colours and short instructions, so children can work independently once they have tried one round with an adult.

Skills your child will learn

Place value beyond the decimal point - tenths, hundredths and how the digits keep their value.
Comparing and ordering - deciding whether 0.7 or 0.65 is larger and explaining why.
Equivalence - seeing that the same amount can be written as a fraction, a decimal or a percentage.
Mental maths - using 10% and 50% as easy stepping stones to other percentages.
Everyday number sense - reading discounts, scores, measurements and test marks with confidence.
Careful checking - estimating first, then confirming the answer.

How to play online and how to print

Open any activity and it loads straight away in the browser - there is nothing to install and no account to create. Children tap or click their answer and get instant feedback, which helps them correct small mistakes before those mistakes turn into habits. If you prefer paper, use the print button on the activity to get a clean black-and-white worksheet that saves ink. Printable sheets are useful for revision folders, morning work, holiday practice and for classrooms where screen time is limited.

A good routine is to play one round online for speed, then print the same activity so your child can show full working. Teachers often print a set for group rotations and keep one copy as a model answer.

Ideas by age

Ages 4-5 (getting ready): decimals come later, but the groundwork starts now. Young children benefit from counting and comparing first. Try Count and Choose to build one-to-one counting, and Bigger or Smaller so the idea of comparing two numbers feels familiar long before decimals appear.

Ages 6-8: focus on the hundred square. Ask your child to shade 3 tenths, then 30 hundredths, and discuss why the shaded area looks the same. Practise placing numbers in order with Number Order, then move to ordering simple decimals such as 0.2, 0.5 and 0.9. Keep sessions short, around ten minutes.

Ages 9-11: children can now join all three forms together. Encourage them to learn the common conversions by heart (1/4 = 0.25 = 25%, 3/4 = 0.75 = 75%) and to find 10% by dividing by ten. Percentages of Amounts works well with shopping examples, cricket scores or marks out of 50.

Tips for parents and teachers

Say the words out loud. Read 0.45 as "zero point four five", not "zero point forty-five", to avoid confusion.
Use the grid as proof. When a child says 0.65 is bigger than 0.7, shade both on a hundred square and let the picture settle the argument.
Connect to money. Rupees and paise, or any price with two digits after the point, make hundredths feel real.
Build from 10%. Once children can find 10%, they can find 20%, 30% and 5% without a calculator.
Praise the method. Ask "how did you work that out?" - explaining the steps matters more than speed.
Mix online and paper. Screens give instant feedback; worksheets build neat written working for exams.

Free for home and classroom

All four activities on this page are completely free to play and free to print, with no sign-up and no personal details needed. Parents can use them for quick daily revision, and teachers can project them on a classroom screen or hand out printed copies to a whole group. Because the same activity exists in both formats, children get consistent practice whether they are learning at home, in a tuition class or at school.

Frequently asked questions

What age should children start learning decimals and percentages?

Most children meet tenths around ages 7 to 8, hundredths at 8 to 9, and percentages at 9 to 11. Younger learners can still enjoy the hundred square activity as a colouring and counting task before formal decimal work begins.

Are these decimals and percentages activities really free?

Yes. Every activity on this page is free to play online and free to print as a worksheet. There is no sign-up, no payment and no limit on how many times you use them at home or in a classroom.

Why does my child think 0.65 is bigger than 0.7?

Children often compare the number of digits instead of place value. Shade both amounts on a hundred square and the difference becomes obvious. The Tenths on a Hundred Square activity is designed to fix exactly this common mistake.

Can I print the worksheets without colour ink?

Yes. Each printable version is designed in clean black and white with large, clear numbers, so it prints well on a basic home or school printer and saves ink when you need many copies.

Do these activities work on a phone or tablet?

They do. The activities open in any modern browser on phones, tablets, laptops and desktop computers. Buttons are large enough for small fingers, and nothing needs to be downloaded or installed first.

How do I help my child find a percentage of an amount?

Start with 10% by dividing the number by ten, then build up. For 30%, find 10% and multiply by three. For 5%, halve the 10% answer. This method needs no calculator and works for most school questions.

How long should a practice session last?

Ten to fifteen minutes of focused practice usually works better than one long session. Short, regular sessions help children remember conversions such as 1/2 = 0.5 = 50% without feeling tired or frustrated.

Can teachers use these activities in class?

Yes. Teachers can project an activity for whole-class discussion, print copies for group rotations, or send printable sheets home as homework. The online and printed versions use the same questions, so practice stays consistent.
