Free Printable Adding and Subtracting 10s Worksheets for Grade 2

Use place-value reasoning first: adding three tens to 46 changes 46 to 76 because the six ones are untouched. Then ask students to represent the same change with base-ten blocks, a number line jump, and an equation.

Include mixed addition and subtraction, sequences that increase or decrease by 10, and missing-number problems such as 57 + ___ = 87. These formats require students to recognize the tens pattern instead of relying on repeated counting.

Watch for answers such as 48 + 30 = 51, which show that a student counted three ones rather than three tens. Other clues are altered ones digits and subtraction answers larger than the starting number.

Use the digital format as a Wayground quiz for immediate class practice, or print the PDF for independent work. Every worksheet includes a complete answer key, and the Wayground for Teachers app can scan and grade completed paper worksheets.

Common Core Grade 2 math extends place-value addition and subtraction to numbers within 1,000. Work with tens prepares students to add or subtract 10 and 100 mentally and to explain which place-value digit changes.

Offer extra time and reduced answer choices to students still developing place-value confidence. A dyslexia-friendly font or wider spacing can help learners distinguish and track digits without changing the mathematical task.

It helps students see two- and three-digit numbers as groups of hundreds, tens, and ones. That understanding supports mental calculation and prepares them to add and subtract larger numbers using place-value strategies.
