2nd Grade Multi-digit Subtraction Quizzes

In 2nd grade, students are expected to become fluent in subtracting two-digit numbers. This is the year they are formally introduced to and practice subtraction with regrouping (or 'borrowing').

A powerful method is to use place value mats and base-ten blocks. Physically exchanging one 'ten' rod for ten 'one' units makes the abstract concept of regrouping concrete and understandable. You can model a problem like 32 - 15 by showing students they can't take away 5 ones from 2 ones without making a trade first.

The most frequent mistake is when students subtract the smaller digit from the larger digit within each column, ignoring their actual positions. For example, in the problem 52 - 28, a student might incorrectly subtract 2 from 8 in the ones place to get 6, leading to an answer of 36.

A good quiz for this level should feature a mix of problems that require regrouping and those that do not. This encourages students to pause and analyze the problem before starting, building their number sense instead of just mechanically applying a new procedure.

You can assign these quizzes as a digital quiz on Wayground for immediate feedback or print them as PDFs for in-class practice or homework. Every quiz comes with a complete answer key, making it easy to review work and identify areas where students need more support.

This topic is central to 2nd grade Common Core math. The standards require students to fluently add and subtract within 100 using strategies based on place value. Mastering two-digit subtraction with regrouping is a key benchmark for meeting this grade-level expectation.
