Multiply Decimals by Powers of 10 is a Grade 5 mathematics worksheet that helps students multiply whole numbers and decimals by 10, 100, and 1,000. Through 20 multiple-choice questions, students apply place-value reasoning to determine how decimal digits change when a number is multiplied by a power of 10, including examples with numbers less than one and larger decimal values. The worksheet also includes a number-sentence item in which students identify the power of 10 needed to produce a given product. Its carefully varied answer choices help reveal whether students are confusing the number of zeros, shifting digits in the wrong direction, or selecting an incorrect place-value result. Use this free printable worksheet for independent practice, review, or a quick formative check, and use the included complete answer key to review student responses efficiently.

FAQs

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

This Grade 5 worksheet covers multiplying decimals and whole numbers by 10, 100, and 1,000 in 20 multiple-choice questions. Students use place-value reasoning to find products such as 7.129 × 100 and 17.5 × 1,000, and identify the power of 10 that makes a number sentence true.

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

Introduce the worksheet by connecting the zeros in 10, 100, and 1,000 to the number of place-value shifts needed in a product. Model one example with a decimal less than one, then have students explain why the correct choice changes when the multiplier increases from 10 to 100 or 1,000. Use the number-sentence item with 0.4 as a discussion prompt about choosing the power of 10 rather than simply calculating a product.

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

Watch for students shifting digits the wrong direction, counting the decimal point instead of the zeros in the multiplier, or moving digits too few or too many places. The multiple-choice distractors also expose confusion between multiplying by 10, 100, and 1,000, especially with values such as 0.085 and 0.74. Check that students distinguish 10² from 10³ and preserve the correct place value in products such as 66.79 × 10².

How do I assign and grade this worksheet?

You can assign Multiply Decimals by Powers of 10 as a printable PDF or as a digital quiz on Wayground. It includes a complete answer key, and printable submissions can be graded by scanning student work with the Wayground for Teachers app.

How can I differentiate this decimal multiplication worksheet for my students?

Use the worksheet’s Advanced Settings to adjust font spacing or choose a larger font size so the decimal expressions and answer choices are easier to read. You can also apply a dyslexia-friendly font or translate the worksheet into another language while students work through the multiplication-by-powers-of-10 items.
