Illinois Grade 2 Math Worksheets — Free Printable PDFs

Steady, friendly practice for Illinois second graders — place value, word problems, time, money, and more, free to print.

A second grader sits at the kitchen table on a gray Illinois afternoon, working out how many more days until a birthday. She counts on her fingers, loses track, starts again, and finally lands on the answer — then beams. That little burst of pride is what second grade math is really about. The numbers matter, but the feeling of “I figured it out” matters just as much.

Second grade is a busy math year. Children learn place value up to 1,000, become fluent in addition and subtraction, solve word problems, measure with rulers, tell time, count money, and read graphs. It’s a lot, and the kids who practice a little at home tend to feel calmer and surer when new skills arrive in class.

We built this free collection of Grade 2 math worksheets to make that home practice simple for Illinois families. Every worksheet is a printable PDF, and every one comes with an answer key. There’s nothing to sign up for and nothing to pay — just choose a page and print it.

The worksheets follow the Grade 2 math standards Illinois has adopted, so the practice your child does at home connects directly to the lessons their teacher is leading, whether you’re in Chicago, Peoria, Rockford, or anywhere in between.

A Tour of the Collection

The collection holds 34 worksheets, divided into eight chapters. Each chapter takes on one major piece of second grade math, and the chapters stand on their own — so you can go straight through or skip to the skill your child needs this week.

Each worksheet uses one clean, consistent design. It opens with a “Key Ideas” box that puts the skill in plain language, followed by a couple of worked examples. Then there’s a set of practice problems, with the answer key on the final page. Once your child has done a worksheet or two, the rhythm becomes second nature.

Here’s everything that’s inside.

Getting the Best Results

The worksheets shine when they’re used with a little care. Here’s what works well for second graders.

Print a single page. One sheet feels achievable, and finishing it gives your child a real sense of progress. A thick stack just feels overwhelming.

Read the Key Ideas box together first. It’s short for a reason — the whole skill, distilled. Two minutes there saves a lot of frustration later.

Walk through the examples aloud. Ask your child to explain the worked example back to you. Teaching it, even to a parent, locks the idea in place.

Treat the answer key as a clue, not a grade. When an answer is wrong, ask “show me your thinking.” You’ll find the exact step that needs another pass.

Circle back to weak skills. If a worksheet felt hard, print a fresh copy a week later. That second attempt is usually where things finally fall into place.

Honest Talk About the IAR

The IAR — the Illinois Assessment of Readiness — is the statewide test Illinois families hear about. Here’s the calm truth: the IAR math assessment doesn’t begin until third grade. There’s no statewide math test in second grade.

That makes second grade the foundation year, and it really is a blessing. Your child has a full year to build number sense, fact fluency, and dependable work habits with no test in sight. Every worksheet in this collection strengthens the precise skills the IAR will look at once your child reaches third grade.

So in second grade, skip the test-prep mindset. The better goal is a confident young mathematician — a child who understands place value, regrouping, word problems, and graphs deeply. That understanding is the best IAR preparation there is, and it starts now.

Do they include answer keys?
Every worksheet has a full answer key on the last page, making it easy to check work together.

My child is struggling. Where do we start?

How much practice is enough?
Short and frequent beats long and rare. Ten or fifteen minutes a few times a week keeps skills fresh.

Can these be used as homework support?
Absolutely. Match the chapter to whatever the teacher assigned, and you’ve got practice that lines up perfectly.
