FAQs

What does the “Multiply Decimals by power of 10” worksheet cover?

This Grade 5 worksheet covers multiplying decimals by 10, 100, and 1,000 through 20 multiple-choice questions. Students apply place-value shifts to numbers such as 7.129, 0.085, and 17.5, and identify the power of 10 that makes an equation such as 0.4 × ___ = 4 true.

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

First model how multiplying by 10, 100, or 1,000 changes each digit’s place value, then solve a few representative examples with students, including decimals less than 1. Have students explain why the correct choice is 8.5 for 0.085 × 100 or 17,500 for 17.5 × 1,000 before assigning the remaining multiple-choice items independently.

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

Watch for students shifting digits the wrong direction, moving them the wrong number of places, or confusing ×100 with ×1,000. Students may also choose answers such as 0.85 for 0.085 × 100 because they do not recognize that multiplication by a power of 10 increases the value; the distractors in the multiple-choice items make these errors visible.

How do I assign and grade this decimal multiplication worksheet?

The worksheet is available as a printable PDF and as a digital quiz on Wayground, and it includes a complete answer key for all 20 multiple-choice questions. After students complete the printable version, you can grade their work by scanning it with the Wayground for Teachers app.

How can I differentiate this worksheet for students who need support with decimal place value?

In the worksheet’s Advanced Settings, adjust font spacing or increase the font size so the decimal multiplication questions and answer choices are easier to read. You can also apply a dyslexia-friendly font or translate the multiple-choice prompts and directions into another language when appropriate.
