FAQs

What does the Multiplying Decimals by Powers of 10 worksheet cover?

This Grade 5 worksheet covers multiplying decimals and whole numbers by powers of 10, including 10, 100, 1,000, 10⁴, and 10⁰. Across 18 multiple-choice questions, students use place value to identify products such as 0.4 × 10 = 4, 0.372 × 10⁴ = 3,720, and 450 × 10⁰ = 450.

How can I use this worksheet to teach multiplying decimals by powers of 10?

Introduce the worksheet by connecting each power of 10 to place value: multiplying by 10, 100, or 1,000 moves a number one, two, or three places to the left in the place-value chart. Model an item such as 45.89 × 10², then have students explain why the product is 4,589 before completing the multiple-choice questions. Use the 10⁰ item to reinforce that any number multiplied by 1 remains unchanged.

What mistakes should I watch for when students complete this worksheet?

Students may shift the decimal the wrong direction, move it the wrong number of places, or confuse the exponent with the product. Watch for errors such as treating 0.0891 × 10⁴ as 89.1 instead of 891, or changing 450 × 10⁰ instead of recognizing that the result remains 450. Students may also overlook place-value changes when multiplying numbers less than 1.

How do I assign and grade this worksheet?

This worksheet is available as a printable PDF and as a digital quiz on Wayground, with a complete answer key for checking all 18 multiple-choice questions. Printable submissions can be graded by scanning student work with the Wayground for Teachers app. The printable format also supports schools that want to reduce screen time.

How can I differentiate this multiplying decimals worksheet for my students?

Use the worksheet’s Advanced Settings to adjust font spacing or choose a larger font size so the decimal multiplication questions and answer choices are easier to read. You can also enable a dyslexia-friendly font or translate the worksheet into another language when those options support access to the place-value practice.
