Grade 2 Math Practice for Delaware Second Graders

Free printable worksheets to help your Delaware second grader build a strong math foundation.

Hand a second grader a ruler and a pencil and ask how long it is, and you’ll get a small lesson in patience. They line up the ruler, then realize they started at the 1 instead of the 0, slide it over, count again, and finally announce, “Seven inches!” Measuring is one of those skills that looks simple and turns out to take real care, which is exactly why second grade spends time on it.

If you’re a Delaware parent or teacher looking for clear, friendly math practice for a second grader, this collection of worksheets is ready for you. It’s free and printable, every page a PDF with the answer key included. There’s no account to create, no email to enter, no signup of any kind. Find the worksheet you want, print it, and start.

Second grade is a foundation year, and a full one. Kids work with numbers up to 1,000, get fluent with addition and subtraction, learn to tell time and count money, measure lengths, read graphs, and notice patterns in arrays. Each skill leans on the one before it.

These worksheets are aligned with the Grade 2 math standards Delaware has adopted, and they’re organized so you can take it one skill at a time, at a pace that fits your child.

What You’ll Find in the Collection

The worksheets are split into eight chapters. Each chapter covers a major area of second grade math, with the skills inside moving from easier to harder. The chapters work on their own, so you can begin wherever your child needs the most help.

Every worksheet starts with a Key Ideas box, a short, plain explanation of the skill, followed by worked examples and then practice problems. The answer key is printed at the bottom of each page. Here’s the whole collection.

• Adding and Subtracting Lengths — Solving word problems by combining or comparing measurements.

Time and Money

Geometry

Using These Worksheets the Smart Way

A stack of worksheets isn’t a plan on its own. A few simple habits turn these pages into real progress.

Do one worksheet at a time. Second graders focus best in short stretches, and a single page worked carefully teaches more than a thick pile rushed through. Open each session by reading the Key Ideas box together, out loud, even on a skill your child thinks they already have. Then walk through the worked examples together, so the first practice problem isn’t the first time they see the method.

When the page is done, look at the answer key together. A wrong answer isn’t a failure, it’s information you can use. Ask your child to talk through how they solved it, and the misunderstanding usually surfaces on its own, ready to be cleared up.

And keep revisiting. If counting coins felt wobbly this week, hand over a fresh worksheet on it next week. That little gap between practice sessions is part of what makes a skill stay for good.

A Few Honest Words About the DeSSA

Delaware uses the DeSSA, the Delaware System of Student Assessments, to track how students are progressing. Here’s the part that takes the pressure off: DeSSA math testing begins in third grade. Your second grader won’t take a state math assessment this year.

That makes second grade the foundation year, and a calm one. There’s no test looming, only time to build the skills the third grade assessment will lean on later. Place value, addition and subtraction fluency, careful word-problem reading, measurement, and reading graphs, those are exactly what DeSSA will eventually check. A second grader who finishes the year comfortable with this material steps into third grade prepared, not panicked.

So treat this year as building, not testing. Relaxed, steady practice now is what makes DeSSA feel like no big deal when it arrives.

Frequently Asked Questions

Are these worksheets free, with no signup?
Yes, completely. Each one is a free printable PDF. No payment, no subscription, and no account or email needed.

Where’s the best place to start?
Start with whatever your child is learning in class right now, or with a topic that’s been giving them trouble. The chapters are independent, so there’s no wrong starting point.

How long should a practice session be?
For most second graders, ten to twenty minutes is plenty. One worksheet, done with attention, makes a good session. Stop before frustration sets in.

What if my child makes the same mistake again and again?
That’s a sign to slow down and revisit the Key Ideas box and examples together. Watch them work one problem aloud, and you’ll usually spot the pattern. Then practice that one skill on a fresh page.

Do these match what Delaware schools teach?
Yes. The topics follow the Grade 2 math standards Delaware has adopted, so they reinforce the work your child is doing in class.
