Multiplying by 10 or 100 is a Grade 4 mathematics worksheet that helps students connect multiplication equations to place-value reasoning. Across 12 multiple-choice questions, students solve practical word problems, interpret tables, identify equivalent expressions, and determine which representation is not equal to a given product such as 427 × 100 or 707 × 10. This worksheet gives students repeated practice recognizing groups of 10 and 100, evaluating expanded and factored forms, and applying the skill to quantities such as crayons, liquid, gravel, and money. It is a free printable worksheet with a complete answer key, making it useful for independent practice, classroom review, homework, or a quick check of students’ understanding of multiplying by powers of 10.

This Grade 4 worksheet uses 12 multiple-choice questions to practice multiplying whole numbers by 10 or 100 through word problems, tables, and equivalent-expression questions. Students must identify valid representations such as groups of 10, groups of 100, and expanded products, while also spotting the one expression that is not equal to a target product.
Introduce the worksheet by modeling how a product changes when a factor is multiplied by 10 or 100, using place-value language rather than relying only on adding zeros. Then work through one table or equivalent-expression item together, asking students to explain why each representation matches or does not match the equation. Students can complete the word problems independently and justify their choices during a class review.
Watch for students confusing multiplication by 10 with multiplication by 100, especially in items involving numbers such as 427, 707, and 909. Students may also choose an expression that is equal when the question asks which one is NOT equal, or misread “hundreds,” “groups of 10,” and “groups of 100” as interchangeable. In the word problems, check that students multiply the number of containers, aquariums, or bills by the stated amount rather than add the quantities.
You can assign this worksheet as a printable PDF or as a digital quiz on Wayground, with the 12 multiple-choice items available in either format. It includes a complete answer key, and printable submissions can be graded by scanning student work with the Wayground for Teachers app. The PDF option also supports classrooms that want to reduce screen time while students practice place-value multiplication.
Use the worksheet’s Advanced Settings to adjust font spacing or increase the font size so the multiplication tables, answer choices, and word problems are easier to read. You can also enable a dyslexia-friendly font or translate the worksheet into another language when appropriate. These changes preserve the worksheet’s focus on multiplying by 10 or 100 and comparing equivalent representations.
