Addition/Subtraction of 2-Digit Numbers gives Grade 2–3 students focused practice solving 15 fill-in-the-blank problems with two-digit addition and subtraction. The set includes equations such as 45 + 35, 56 − 19, 80 + 15, and 80 − 78, requiring students to work with ones and tens, regroup when needed, and record each answer accurately, including a result of 100 and a subtraction answer that may be written as 2 or 02. This mathematics worksheet supports independent practice, a quick skills check, or review after modeling two-digit computation. Students must distinguish addition from subtraction, align place values, and apply efficient calculation strategies across mixed operations rather than relying on a single repeated procedure. It is a free printable worksheet with a complete answer key, making it useful for classroom practice, homework, intervention, or teacher-led correction with Grade 2 and Grade 3 learners.

WorksheetsAnswer KeyThis Grade 2–3 mathematics worksheet covers solving 15 fill-in-the-blank equations involving mixed two-digit addition and subtraction. Students build computation accuracy by applying place-value strategies, regrouping when needed, and recording answers such as 2 or 02 for 80 − 78 and 100 for 50 + 50.
Model one addition and one subtraction equation from the worksheet, showing how to align tens and ones and decide whether regrouping is needed. Then have students complete the mixed set independently or in pairs, asking them to explain the steps behind selected answers such as 42 + 29, 55 − 36, and 80 − 78 before reviewing the answer key.
Watch for students adding or subtracting digits without respecting tens and ones, choosing the wrong operation, or failing to regroup in problems such as 42 + 29 and 56 − 19. Also check answers with zeroes and place value, especially 80 − 78, where students may omit the leading zero, and 50 + 50, where the result is 100.
Wayground provides this worksheet as a printable PDF and as a digital quiz, and it includes a complete answer key for checking all 15 fill-in-the-blank equations. Printable submissions can be graded by scanning student work with the Wayground for Teachers app, while the digital version supports online completion and grading.
Use the worksheet’s Advanced Settings to adjust font spacing or choose a larger font size so the two-digit equations and answer blanks are easier to read and organize. You can also enable a dyslexia-friendly font or translate the worksheet into another language when those options support access to the computation tasks.
