About this resource

This robust set of decimal operation worksheets offers unlimited practice to build fluency in adding and subtracting numbers to the tenths, hundredths, and thousandths. With a simple click, all numbers are randomised so you can generate endless customised practice pages on 6 essential topics:

  • Adding 2 decimals to the tenths

  • Subtracting 2 decimals to the tenths

  • Adding 2 decimals to the hundredths

  • Subtracting 2 decimals to the hundredths

  • Adding 2 decimals to the thousandths

  • Subtracting 2 decimals to the thousandths


Each vertically formatted worksheet contains 12 computation problems neatly organised in a clear, easy-to-use layout suited for written work. Answers provided on the second page.


The unlimited supply means you can create specialised practice sets all year long for homework, classwork, test prep, cover lessons, or learning station activities. Easily differentiate by adjusting decimal place values or mixing question types. Give small groups tailored worksheets to re-teach or challenge students. The options are endless!


As the worksheets are self-explanatory, students can work independently while you teach small groups. Ideal for learning stations, cover lessons, or interventions.


The randomising feature instantly refreshes new numbers with one click, creating 100% new practice every time. No need to ever make photocopies!
These PDFs work offline with the Adobe Reader on all devices – Windows or Mac computers, laptops, touchscreen devices like iPads, and interactive whiteboards.


Perfect for upper primary and lower secondary pre-algebra classes to reinforce decimal operations. Build procedural fluency through deliberate, focused practice!
