Powers of 10 Warm up is a free printable Grade 5 mathematics worksheet that helps students multiply decimals and whole numbers by powers of 10. The worksheet contains 8 fill-in-the-blank questions, including items such as 3 × 0.01 and 1.11 × 100, so students practise determining the product and recording it in correct decimal notation. This warm-up supports fluency with how multiplying by powers of 10 changes a number’s value and decimal placement. Students complete each product independently, making it useful for introducing or reviewing decimal multiplication before a lesson, as a short practice activity, or as an exit check. An answer key is included for efficient review and feedback.

Answer KeyThis Grade 5 mathematics worksheet helps students multiply decimals and whole numbers by powers of 10 and write each product in correct decimal notation. Its 8 fill-in-the-blank items, including 3 × 0.01 and 1.11 × 100, require students to apply the effect of a power of 10 rather than select an answer from a list.
Introduce the fill-in-the-blank format by modeling how multiplying by 0.01 or 100 changes a number’s value and decimal placement. Then have students complete the 8 items, explain how they determined each product, and use the answer key to discuss why a product such as 3 × 0.01 is 0.03 while 1.11 × 100 is 111.
Students may move the decimal in the wrong direction when multiplying by 0.01 or 100, or move it the wrong number of places. Also watch for omitted leading or trailing zeros and incomplete entries such as writing .03 or 111. without consistently recording the decimal product in standard notation.
The worksheet is available as a printable PDF and as a digital quiz on Wayground, and it includes a complete answer key for all 8 fill-in-the-blank questions. For printed submissions, you can grade student work by scanning it with the Wayground for Teachers app.
In the worksheet’s Advanced Settings, adjust font spacing or font size to make the 8 fill-in-the-blank items easier to read and complete. You can also apply a dyslexia-friendly font or translate the worksheet into another language while keeping the decimal multiplication practice intact.
