About these worksheets
The classic decimal misconception is “longer means bigger”: 3.09 looks longer than 3.4, but 3.4 is greater. Every sheet in the set is built around exactly that trap — roughly half the pairs put a two-decimal number against a one-decimal number, so the misconception gets confronted again and again. The fix is place value: compare tenths with tenths before even looking at hundredths, or mentally pad 3.4 to 3.40.
Grade level: these worksheets are part of our 4th grade math worksheets collection.
Frequently asked questions
Why does 3.4 beat 3.09?
Compare tenths first: 4 tenths versus 0 tenths — done. Padding helps too: 3.4 is 3.40, and 40 hundredths beats 9 hundredths.
Why so many trap pairs?
Because “longer is bigger” survives gentle worksheets. Confronting the misconception repeatedly, with the answer key confirming each time, is what breaks it.
Which grade covers comparing decimals?
Decimal comparison to hundredths is 4th grade core and a 5th grade warm-up staple.
