Multiplying Decimals By 10 100 Practice Activities
Focused Grade 5 worksheets help students multiply decimals by 10 and 100 by understanding place value movement, not just shifting digits.
Practice that builds confidence
What this skill builds
These Grade 5 decimal multiplication worksheets give students steady practice multiplying decimal numbers by 10 and 100. Children learn how each digit’s value changes as a number becomes 10 times or 100 times as large.
The printable activities include place-value focused problems, decimal point reasoning, mixed practice, and short answer tasks that help students explain the pattern. They are designed for the Decimals Multiplication unit and keep the focus tightly on powers of 10.
Multiplying decimals by 10 and 100 is a key Grade 5 bridge between place value and decimal operations. Students see that 4.7 × 10 = 47 and 4.7 × 100 = 470 because each digit moves to a place with a greater value. The goal is not to memorize a trick, but to understand tenths becoming ones, hundredths becoming tenths, and ones becoming tens or hundreds.
How the worksheets progress
The practice begins with clear multiplication by 10, then extends to multiplying by 100. Students may work with decimals such as tenths, hundredths, and whole-number results, noticing when zeros are needed as placeholders. Mixed items then ask children to decide whether the product should be 10 times or 100 times greater, strengthening number sense and accuracy.
A simple parent routine
At home, ask your child to read the number aloud before solving: “3.26 is three and twenty-six hundredths.” Then have them say what will happen when it is multiplied by 10 or 100. After they write the answer, ask, “Is the product larger? Does the size make sense?” This quick check helps prevent answers that are accidentally divided instead of multiplied.
Classroom uses for teachers
Teachers can use these printables for independent practice, math centers, warm-ups, homework, or a quick check after a place value lesson. They also work well for small groups: one student solves, another explains the place-value movement, and a third checks whether the decimal point placement is reasonable.
Common errors to watch for
Some students “move the decimal” the wrong direction, remove necessary zeros, or treat 10 and 100 as if they work the same way. Watch for answers like 0.58 × 10 = 0.058 or 6.04 × 100 = 64. Encourage students to compare the original number and product: multiplication by 10 or 100 should make the number greater.

Why iBloom worksheets help
iBloom worksheets keep the practice focused, visual, and manageable. A child-friendly strategy is: “Think place value first, then write the new number.” Say the original number, count one place for ×10 or two places for ×100, fill any empty places with zeros, and reread the product to check that it makes sense.
Helpful answers
Frequently asked questions
What do Grade 5 students practise in these worksheets?
They practise multiplying decimal numbers by 10 and 100, using place value to understand how digits shift to greater-value places.
Should children just move the decimal point?
The decimal point shortcut can be useful, but students should first understand the place-value change. Each digit becomes 10 times or 100 times greater, depending on the multiplier.
What mistakes are common when multiplying decimals by 10 and 100?
Common mistakes include moving digits the wrong way, losing zeros that are needed as placeholders, and giving an answer that is smaller even though the operation is multiplication.
How can I help my child check an answer?
Ask whether the product is larger than the starting decimal and whether it is 10 times or 100 times as large. Reading both numbers aloud also helps students catch place-value errors.
Can these worksheets be used in class math centers?
Yes. They work well for math centers, warm-ups, independent practice, homework, or small-group review during a decimals multiplication unit.
