This Free Printable Worksheet Site Surprised Me| 15Worksheets.com Review
If you’ve homeschooled for more than five minutes, you’ve probably typed “free printable worksheets for homeschoolers” into Google and ended up either disappointed or overwhelmed. Most of the time, the results lean heavily toward elementary grades—cute coloring pages, basic phonics sheets, and endless math drills that don’t go past single-digit addition. That’s great if you’ve got little ones, but what about middle or high school?
I’ll be honest: I didn’t think we’d get much use out of 15Worksheets.com for our homeschool right now since we’re in 9th grade. Like most free worksheet websites, I assumed it would stop being helpful once we hit high school. But I was wrong. What I found was a surprisingly deep library of printables that not only covered every subject but also lined up beautifully with our 9th grade curriculum this year.
So today I want to tell you about it as part of a new series of reviews I’m writing to gather the best free homeschool resources out there. You’ve probably heard of big names like Khan Academy or Education.com, which notes that worksheets are still one of the most widely used classroom tools.
But what excites me most is uncovering hidden gems like 15Worksheets.com that take those same benefits and add extra value for homeschool families. Over time, I’ll be building a list of free resources for families who need solid, no-cost support.

What Is 15Worksheets.com? (Free Online Worksheets for PreK-12)
15Worksheets.com started with a simple idea: 15 retired teachers each contributing 15 printable worksheets on topics they knew best. From there, the collection grew and today the site offers more than 25,000 free worksheets across all grade levels, from Pre-K all the way through high school.
The subjects span everything you’d expect (and more): math, science, reading, writing, grammar, social studies, vocabulary, spelling, and even seasonal or holiday themes or SAT. Within each subject, you’ll find subtopics like “Newton’s Laws of Motion,” “Simplifying Algebraic Expressions,” “Types of Irony,” or “Animal Cells.” Each subcategory has at least 15 worksheets, often with an included answer key.
From tracing letters in kindergarten worksheets to analyzing Shakespeare in high school, the range is impressive. Whether you’re teaching 1st grade, middle school, or high school, you’ll find something useful.
What really sets this site apart from other homeschool printable worksheets is how easy it is to use. There are no logins, no hidden paywalls, and no complicated “online curriculum” systems to navigate. You simply click on the worksheet you need, download it, and print. That’s it. It’s refreshingly simple in a world where so many so-called “free” printables come with a catch.
We all got together and came up with the idea to provide 15 supplemental worksheets on every topic we could possibly imagine. Please do not hold us to the exact number of 15 though. Sometimes we create a great deal more worksheets for a topic. This is very fun for us. We are sure that our work provides a huge value for teachers, parents, tutors, homeschoolers, and educators everywhere. Especially since it is free (for educational purposes).

Our 9th Grade Experience with 15Worksheets.com
When I first clicked around, I wasn’t expecting much for high school. But I was genuinely surprised to see how many worksheets lined up perfectly with our 9th grade curriculum choices. It felt like someone had peeked into our homeschool plan and built resources to match. Alongside skill practice, you’ll also find lighter printable activities that keep lessons engaging.
In language arts (we’re using Aim Academy as our main high school ELA curriculum this year), we found worksheets on:
- Types of irony
- Types of conflict and antagonists
- Using text evidence
- Tragedy, including a focus on Romeo and Juliet (a core text for our 9th grade this year)
- Foreshadowing, aporia, and other rhetorical devices
These gave Marc a chance to practice skills he needed for class discussions and essays.
In math, we pulled out worksheets on simplifying algebraic expressions and solving multi-step equations. These were a great way to reinforce what he was already learning with Mr D Math without me having to worry about finding extra practice.
Since Marc is STEM-focused, we also had fun diving into the science worksheets. He worked through sheets on the parts of an atom, chemical formulas, animal cells, and Newton’s laws of motion. We even stumbled across a worksheet on dark matter, which sparked a longer conversation and sent him down a rabbit hole of research (always a win in my book).
STEM Pintables:
These are some of my favorite STEM printables that I’ve created for curious kids like my own. They’re simple to use, but packed with real science and engaging activities. If your child loves asking “why?” and exploring how the world works, these resources are made to keep that spark alive while making learning at home easier for you.
The social studies section tied in beautifully with our geography choice for this year. We practiced labeling countries, studied the international date line, and used the worksheets as quick checks to reinforce map skills. The social studies worksheets cover topics like countries, historical events from the United States and the world, map work, and many more.
And then there were the extras like SAT vocabulary prep and even Mad Libs. Marc LOVES Mad Libs, and I turned them into a challenge by asking him to use complex or academic vocabulary in his answers. He had a blast, and I got to sneak in some higher-level word practice without any complaints.
What I loved most was how fun and flexible the site turned out to be. Whether we needed a serious skill-builder or something light for a Friday, there was always a free printable ready to go.
Strengths of 15Worksheets.com
After using it regularly for a few weeks now, I can honestly say that 15Worksheets.com surprised me in the best way. It isn’t just another online worksheet site with a handful of random activities—it’s a genuinely useful tool that I see us coming back to again and again. Here’s why:
1. Covers every level, from Pre-K through high school.
This is probably its biggest strength. Most “free worksheet” sites stop being helpful once your child outgrows basic phonics or single-digit math. But 15Worksheets.com goes the distance. You’ll find everything from tracing letters for preschoolers to analyzing rhetorical devices for high schoolers. As a homeschool mom with a teen, I really appreciate that the site hasn’t forgotten older grades.
2. Wide subject coverage across the curriculum.
It’s not limited to one area. The site includes English, math, science, social studies, reading comprehension, vocabulary, spelling, and even holiday-themed printables. I’ve used worksheets on irony and tragedy in literature, algebraic expressions in math, Newton’s laws in science, and map labeling in geography—all in the same week. That kind of breadth makes it feel like a real one-stop shop for reinforcing our curriculum.
For example he collection of printable math worksheets alone covers everything from tracing numbers and basic addition to algebra.
3. Simple and straightforward access.
There’s no login, no membership, no hidden “upgrade to premium” button. You just pick the worksheet you want, click download, and print. It’s such a relief compared to other sites where you need to sign up, create an account, or sift through endless pop-ups before you can actually access a single page. Each worksheet downloads instantly as a PDF file, so you can print it right away.
4. Variety of worksheet styles.
Not all worksheets are created equal, and I like that this site mixes it up. Some are straightforward practice drills (great for mastering multi-step equations), while others are more informational or critical-thinking focused (like those on rhetorical devices or text evidence). This variety makes it easier to choose the right tool depending on whether I want Marc to review facts or stretch his thinking.
5. Answer keys included.
This is a practical but important feature. Many of these worksheets come with answers, which saves me time and gives Marc the option to check his own work. It also means I can assign a worksheet independently without having to preview every single question in advance.
6. Fun extras that keep learning light.
We stumbled across SAT vocabulary prep, which I was thrilled about, but what really hooked Marc were the Mad Libs. They’re silly, yes, but they gave me the chance to challenge him to sneak in higher-level vocabulary words. That turned something fun into something academic, and he didn’t even realize it. Those kinds of unexpected finds make the site more than just drill-and-kill.
7. Free means low-risk experimentation.
Because the entire library is free online, I never hesitate to try something new. If a worksheet isn’t a perfect fit, I don’t feel guilty about wasting money. That freedom to experiment has actually led us to discover some great topics—like the dark matter worksheet that sparked a rabbit-trail research session.
All of these strengths add up to one conclusion: 15Worksheets.com is a flexible, time-saving, and genuinely helpful resource that can slide into almost any homeschool curriculum, whether you’re teaching little ones or guiding a teenager through high school.
Limitations to Consider
No resource is perfect, and 15Worksheets.com has one small limitation: the worksheets are not labeled by grade (except for preschool and kindergarten). But honestly, that isn’t always a bad thing because it gives you the freedom to pick and choose based on your child’s skill level rather than being boxed into a specific grade range.
How to Use Free Printable Worksheets for Homeschoolers
The easiest mistake with a site like this is to just print off random worksheets because they look interesting. That’s fun once in a while, but where 15Worksheets.com really shines is when you use it to support what you’re already teaching. Because these are free homeschool printables, you can print as many as you need without worrying about cost.
Here’s what’s worked best for us:
- Search by topic you’re covering for various options. If you’re in the middle of a literature unit, look up worksheets on irony, foreshadowing, or rhetorical devices. Studying fractions? There’s a full section of math worksheets on simplifying, dividing, and multi-step equations. Matching worksheets to your current curriculum makes them meaningful rather than just busywork.
- Build into unit studies. The site works beautifully for unit study themes because it spans every subject. For example, when studying space, you can combine science worksheets on dark matter with reading comprehension passages about astronomers and vocabulary sheets on root words. It’s a simple way to keep your unit multi-dimensional without spending extra money on resources.
- Reinforce tricky concepts. If your child needs more practice with text evidence or labeling countries on a map, grab a few targeted worksheets for extra review. Because they’re free printables, you can print as many as you need without worrying about cost.
- Mix in some fun. Don’t underestimate the SAT vocabulary Mad Libs, or seasonal activities.
The bottom line: don’t treat this as a grab-bag of random worksheets. Use it strategically, tied to your topics and unit studies, and it becomes a powerful, flexible tool in your homeschool.
