Mathematics
This Grade 3 mathematics worksheet helps students multiply a one-digit number by a multiple of 10, such as 5 × 30, 3 × 80, and 9 × 80. Students use place-value reasoning and factor decompositions, including expressions such as 8 × (4 × 10) and (4 × 8) × 10, to connect basic multiplication facts to larger products. The 10-question worksheet combines 3 multiple-choice questions, 3 multiple-select questions, and 4 fill-in-the-blank word problems. Contexts involving game cards, folders, lemonade, daily sit-ups, and zoo memberships give students practice applying multiplication of multiples of 10 to real-world quantities. It is a free printable worksheet with an answer key for Grade 3 math practice, review, or formative assessment.

This Grade 3 worksheet focuses on multiplying one-digit numbers by multiples of 10, such as 4 × 60, 3 × 80, and 9 × 80. Its 3 multiple-choice, 3 multiple-select, and 4 fill-in-the-blank items ask students to solve word problems and identify equivalent expressions by decomposing factors, such as 8 × 40 = (8 × 4) × 10.
First model a problem such as 3 × 80 by rewriting 80 as 8 × 10, then connect it to (3 × 8) × 10 = 240. Have students explain why each selected expression equals 8 × 40 or 4 × 60 before completing the multiple-select items, and finish with the word problems so they apply the strategy to quantities such as folders, sit-ups, and memberships.
Students may multiply the nonzero digits correctly but omit the factor of 10, giving 24 instead of 240 for 3 × 80 or 32 instead of 320 for 8 × 40. In the multiple-select questions, they may choose only one equivalent expression, accept an expression with the wrong product, or overlook that the number of groups and quantity in each group must both be used in the word problems.
This multiplying multiples of 10 worksheet is available as a printable PDF and as a digital quiz on Wayground, and it includes a complete answer key. You can grade printable submissions by scanning student work with the Wayground for Teachers app, or review responses from the digital quiz.
Use the worksheet’s Advanced Settings to adjust font spacing or font size so the multiplication expressions, 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 that better supports students working through the multiple-choice, multiple-select, and fill-in-the-blank items.
