Free Printable Number and Operations in Base Ten Worksheets for Grade 2

In 2nd grade, students extend their understanding of the base-ten system to three-digit numbers (up to 1,000). Key skills include counting within 1,000, skip-counting by 5s, 10s, and 100s, comparing three-digit numbers, and fluently adding and subtracting within 100.

Use place value mats and base-ten blocks to make regrouping tangible. To subtract 17 from 42, for example, have students model 4 tens and 2 ones, then physically trade one ten-rod for ten ones to see that they now have 3 tens and 12 ones, making the subtraction possible.

A classic error in subtraction with regrouping is when students subtract the smaller digit from the larger one in each column, regardless of whether it's on the top or bottom. For 52 - 28, a student might incorrectly calculate the ones place as 8 - 2 = 6.

The worksheets provide targeted practice using the greater than (>), less than (<), and equal to (=) symbols to compare two- and three-digit numbers. Exercises also include ordering a set of numbers from least to greatest and identifying the largest or smallest number in a group.

You can print the worksheets as PDFs for hands-on practice, allowing students to use manipulatives or draw models alongside the problems. Alternatively, assign them as a digital activity on Wayground. Either way, a full answer key is included to make grading or checking work efficient.

This content is aligned with the Common Core's Grade 2 Number & Operations in Base Ten (NBT) domain. The standards emphasize understanding three-digit place value and using that knowledge to fluently add and subtract within 100, both of which are heavily practiced in these worksheets.
