Grade 4 Decimals Worksheets — Compare & Add Tenths
Fourth grade is where decimals stop being a strange dot and start being a place-value idea. Grade 4 splits that across six separate sheets: Reading & Writing Decimals, Comparing Decimals, Ordering Decimals, Adding Decimals, Subtracting Decimals and Decimals & Fractions. Comparing Decimals is the one to open first — it puts two decimals side by side for <, > or =, including the pairs that trip everyone up, like 10.7 against 10.68.

Each one generates a different kind of question, with its own three levels and answer key.
- Reading & Writing DecimalsSay a decimal in words, name the value of a digit, and break a number apart.
- Comparing DecimalsDecide which decimal is greater using <, > or =.
- Ordering DecimalsPut a set of decimals in order from smallest to largest.
- Adding DecimalsLine up the decimal points and add.
- Subtracting DecimalsLine up the decimal points and subtract.
- Decimals & FractionsConvert between decimals and fractions in simplest form.

Grade levels follow the progression common to most English-language curricula — not one specific national curriculum. Every level shows exactly what it generates, so you can check the fit with your own program. See the full scope & sequence →
Why comparing comes before calculating
The single biggest Grade 4 misconception is reading the digits after the decimal point as if they were a whole number, so a child decides 0.65 is bigger than 0.7 because "sixty-five beats seven". Comparing Decimals exists to confront that head-on. It opens on pairs written to the same length, then moves to Different lengths, which deliberately mixes numbers written to one place with numbers written to two and includes pairs that are genuinely equal, such as 3.3 and 3.30, so students have to think in place value rather than digit count. Its third level, Decimals and fractions, goes further still and asks for 5.4 against 5 2/5.
The fix that sticks is to say the number out loud in words — "seven tenths" versus "sixty-five hundredths" — and then rewrite both to the same number of places: 0.70 against 0.65. Once a student adds the placeholder zero without being told to, the comparison stops being guesswork and the arithmetic sheets become far more reliable. Ordering Decimals is the natural next step, sorting three or four numbers rather than two.
Getting the first sums right
Adding Decimals and Subtracting Decimals each open below 1 — sums and differences in tenths like 0.4 + 0.3 — so the focus stays on the idea that four tenths and three tenths make seven tenths, exactly like 4 + 3 in the ones column. Their second levels, Carry across the point and Borrow across the point, bring in whole-number parts and are built so a carry or a borrow is actually needed: 7.3 + 5.7 and 3.2 − 2.3 rather than the tidy pairs that hide the skill. Adding Decimals finishes with Three numbers; Subtracting Decimals finishes with From a whole number, where 14 − 5.3 forces the missing tenths to be written in.
Insist on writing the decimal points underneath each other, even for a two-number sum a child could do mentally. That habit is the whole game in Grade 5, and it is far easier to establish now than to repair later. Ten to fifteen questions is a sensible session at this age; use Shuffle for a fresh set at the same level tomorrow.
Frequently asked questions
▸What do Grade 4 students need to know about decimals?
Reading and writing decimals to tenths and hundredths, understanding that 0.7 and 0.70 are the same value, comparing two decimals (or a decimal with a simple fraction), adding or subtracting simple tenths, and moving between decimals and simple fractions such as 1/2, 1/4, 1/5, 1/10 and 1/20. Every sheet here sits inside that range.
▸Why do children think 0.65 is bigger than 0.7?
They are comparing the digits after the point as a whole number instead of by place value. Rewriting both to the same number of places — 0.70 against 0.65 — fixes it instantly, and the Different lengths level of Comparing Decimals is built around exactly that pairing.
▸Which decimals sheets does Grade 4 have?
Six, each printed separately. Reading & Writing Decimals moves between words, digits and expanded form. Comparing Decimals writes <, > or = between two numbers. Ordering Decimals sorts three or four. Adding Decimals and Subtracting Decimals each run from no carrying or borrowing up to the harder cases. Decimals & Fractions converts between the two notations. Each sheet carries its own three levels, so the level control changes how hard that skill is rather than which skill you get.
▸How many decimal questions should a Grade 4 sheet have?
Ten to fifteen is plenty while the concept is new — the thinking matters more than the volume. Use the question-count stepper to size the sheet, and print the answer key so a child can check a row at a time rather than waiting for marking.
