What each level generates

Grade 4 adding decimals — the exact skill behind each difficulty setting, straight from the generator.

  1. Level 1No carrying
  2. Level 2Carry across the point
  3. Level 3Three numbers

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 →

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.
