Grade 4 Decimals Worksheets — Free Printable PDF
Free Grade 4 decimals worksheets — tenths and hundredths, decimal-fraction equivalents, comparing decimals. Common Core 4.NF.C aligned.
Decimals are introduced in Grade 4 as a new way to write fractions whose denominators are 10 or 100. That framing matters — children who learn decimals as 'a different number system' get confused, while children who learn them as 'just another way to write 7/10 = 0.7' don't. Our sheets follow the second approach because it matches the Common Core 4.NF.C standard.
These Grade 4 decimal sheets cover: writing fractions with denominator 10 or 100 as decimals, decimal place value (tenths, hundredths), comparing decimals using <, >, =, plotting decimals on a number line, and converting between fraction and decimal notation. We don't introduce decimal addition or subtraction yet — that's Grade 5 (5.NBT.B.7).
Pair with Math Quiz Challenge for mixed practice. Decimals build directly on Grade 3 fraction understanding, so if your child is shaky on fractions, drop back to those sheets first. Free, no signup.

Frequently Asked Questions
Why are decimals introduced as fractions?+
Because that's what they ARE. 0.7 is just another way to write 7/10. Common Core 4.NF.C.5 makes this connection explicit.
Should Grade 4 add decimals?+
No — decimal arithmetic is a Grade 5 standard. Grade 4 focuses on understanding what decimals MEAN and how to compare them.
Tenths and hundredths only?+
Yes. Thousandths come in Grade 5 (5.NBT.A.3).
Are these aligned to Common Core?+
Yes — they cover 4.NF.C.5, 4.NF.C.6 and 4.NF.C.7.
