1st Grade Multi-digit Subtraction Quizzes

In 1st grade, multi-digit subtraction focuses on building foundational place value concepts. Students typically learn to subtract a one-digit number from a two-digit number (e.g., 17 - 5) and subtract multiples of 10 from other multiples of 10 (e.g., 60 - 20), generally without requiring regrouping.

Use concrete manipulatives like base-ten blocks or a hundred chart. On a hundred chart, for example, subtracting 10 is a simple jump up one row. These visual methods help students understand the relationship between numbers and the concept of 'ten less' before they learn a formal algorithm.

Start with problems that don't require regrouping, such as subtracting a multiple of 10 from a two-digit number (e.g., 45 - 10). Visual aids are key; quizzes that include pictures of base-ten blocks or number lines provide crucial support as students connect concrete models to abstract numbers.

The most common difficulty is a weak understanding of place value. Students may try to subtract digits in the wrong columns or treat a two-digit number as two separate single digits. Consistent practice with place value charts and base-ten blocks can help address this.

These quizzes can be used as printable PDFs for hands-on practice, which is especially helpful for young learners who benefit from tactile activities and reduced screen time. Each quiz includes a full answer key, and you can use the Wayground for Teachers app to quickly scan and grade completed paper assignments.

These quizzes support the Common Core focus for Grade 1, which emphasizes using place value understanding to subtract within 100. The activities are designed to reinforce the strategy of subtracting multiples of 10 from two-digit numbers, a key skill at this grade level.
