Short answer: The most reliable places to get ready-to-use, Common Core-aligned project-based learning units are the PBLWorks project library (free account, 70+ standards-aligned units), Defined Learning (paid, school or district license), EL Education’s K–8 Language Arts curriculum (free account online, built around modules that end in real-world performance tasks), and Teachers Pay Teachers, where individual teachers sell units tagged with standards. Whatever you pick, check the alignment yourself: look for specific standard codes, then make sure the final product and rubric actually assess those standards.
“Common Core aligned” is one of the easiest labels to put on a product and one of the hardest to prove. This page lists sources we could verify, says plainly what each is good at, and then shows a quick way to test any unit’s alignment claim before you spend money or planning time on it. If you’re newer to PBL, start with our project-based learning guide first.
Where can I get ready-to-use PBL units aligned to Common Core?
Start with PBLWorks and EL Education for free, then look at Defined Learning or Teachers Pay Teachers if you need something they don’t cover.
Here’s how the main options compare. Prices and terms change, so confirm on each site before you buy.
| Source | Cost | Grades | Standards claim | Best for |
|---|---|---|---|---|
| PBLWorks project library | Free account | Filter by grade | Standards-aligned (check each project) | Teachers who want vetted PBL design |
| Defined Learning | Custom quote | K–12 | State and national standards; alignment docs on request | Schools buying a full platform |
| EL Education K–8 Language Arts | Free account online; print and trade books cost extra | K–8 | Rated Meets Expectations by EdReports (grades 6–8, 2016) | Middle school ELA teams |
| Teachers Pay Teachers | Free to paid, per resource | All | Set by each seller | One-off units on a specific topic |
| Elevate the Norm (this site) | Free, no email | 6–12 | Not tagged to standard codes | Secondary social studies and science ideas |
Is the PBLWorks project library worth using?
Yes, and it’s the first place to look because the projects are designed around a published PBL model and cost nothing beyond a free account.
PBLWorks, the organization formerly known as the Buck Institute for Education, says its MyPBLWorks platform holds 70+ standards-aligned project units and that you can get started with a free account. The project library lets you filter by grade level and subject, and each project overview lists the grades and subjects it fits.
What it’s good at: the projects come from the same organization that publishes the Gold Standard PBL model, so driving questions, critique, and public products are built in. What to watch: “standards-aligned” on the library page doesn’t name a single framework, so open each project and check which standards it actually lists. Some may cite Common Core; others may cite science, social studies, or state standards.
If you’d rather learn the design model than download projects, the Gold Standard approach is laid out in Setting the Standard for Project Based Learning (ASCD) by John Larmer, John Mergendoller, and Suzie Boss, which includes a chapter titled “What Is Gold Standard PBL?” ASCD lists it at $37.95, or $30.36 for members. It’s a how-to-design book, not a box of units.
What does Defined Learning offer?
Defined Learning is a paid K–12 platform of scenario-based performance tasks with rubrics built in, sold to schools and districts rather than individual teachers.
According to its product page, every task includes built-in rubrics, exemplars, and student work samples, and districts can map the library to their own standards and scope and sequence. Its FAQ says the curriculum is aligned to state and national standards in ELA, math, science, social studies, and computer science, that pricing is a custom quote based on enrollment and products, and that the team can provide alignment documentation for your specific state on request.
That last part is the useful bit. If your school is considering it, ask for the alignment document for your state and grade band before signing anything. It’s a reasonable request, and Defined says it’ll provide it.
Is there a free Common Core curriculum that’s already project-heavy?
EL Education’s K–8 Language Arts curriculum is the strongest free-to-access option for middle school ELA, though it’s a full curriculum rather than standalone projects.
EL Education says teachers can create a free account on its curriculum website to access modules and lesson plans. Its partner Open Up Resources describes the curriculum as K–8 with a culminating real-world performance task and offers it in print and digital formats. The grades 6–8 tools page includes curriculum maps listing module topics, targets, and standards, a Common Core-aligned interventions guide, and a trade book list you’ll need to purchase.
On alignment, EdReports rated the grades 6–8 materials Meets Expectations on all three gateways in its 2016 review. EdReports notes that older v1.0 reviews may not fully match its current priorities, so treat that as a good sign, not a final word.
Limits worth knowing: it stops at grade 8, it’s ELA only, and it’s designed to be taught as a sequence. Pulling one module out works, but you lose some of the built-up knowledge the design depends on.
Can I trust Common Core units on Teachers Pay Teachers?
Some are excellent, but alignment on TPT is self-reported by each seller, so you have to verify it yourself.
A search for project based learning common core on TPT returns more than 35,000 results. The sidebar lets you filter by grade band, subject, and price (including a Free option), and listings show the standards the seller tagged. That’s helpful for narrowing the pile, but those tags come from the seller, not from an independent review.
Practical tips for TPT:
- Open the preview and find the standards page. If there isn’t one, move on.
- Look for a rubric in the preview. A PBL unit without a rubric isn’t ready to use.
- Read the reviews for comments about whether it worked in a real class, not just whether it looked nice.
- Start with the Free filter. Many sellers post free samples.
How do I check a unit’s Common Core alignment myself?
Match the standard codes to the assessment: if the final product and rubric don’t measure the standard, the unit isn’t aligned, no matter what the cover says.
This takes about ten minutes per unit:
- Find the codes. A real alignment claim names specific standards, like WHST.9-10.1 (“Write arguments focused on discipline-specific content”) or math practice MP4, Model with mathematics. “Aligned to Common Core” with no codes means nothing.
- Read the standard on the official site. Look it up at thecorestandards.org. Note the verb: write, analyze, cite, model.
- Find where students do that verb. If the standard says “write arguments,” students should write an argument, not fill in a graphic organizer about one.
- Check the rubric. Each listed standard should show up as a row (or part of one) in the rubric. Our free editable PBL rubric shows how to separate individual content knowledge from group work.
- Count the standards. A two-week unit claiming fifteen standards is decorating, not aligning. A few deeply assessed standards is more honest.
| Green flag | Red flag |
|---|---|
| Specific codes listed per lesson or product | “Common Core aligned” on the cover only |
| Rubric rows match the listed standards | Rubric grades neatness, color, and effort |
| Students produce the thing the standard describes | Standards listed that no task touches |
| A few deeply assessed standards | A long list of standards for a short unit |
If your school uses standards-based grading, our standards-based grading rubric starter pack makes this matching step easier.
Where does Elevate the Norm fit?
This site offers free secondary PBL unit ideas and rubrics, but they aren’t tagged to Common Core codes, so you’d add the standards yourself.
Disclosure: Elevate the Norm is this site’s own framework, built by a grades 6–12 social studies teacher, and it hasn’t been independently evaluated. Everything in our free resources library is free with no email gate. For ready-made unit ideas, see 10 history project units for grades 7–12 and 25 science PBL projects for grades 6–12. If you’re building your own, the 7 steps of project-based learning walks through the design.
For assessment, see our companion guides on PBL rubric bundles for middle and high school and PBL rubrics for high school STEM. For the bigger picture on classroom systems, the classroom culture frameworks Q&A covers 63 common questions.
Frequently Asked Questions
Where can I find free Common Core aligned PBL units?
The PBLWorks project library offers 70+ standards-aligned project units with a free account, and EL Education’s K-8 Language Arts curriculum is accessible online with a free account. Teachers Pay Teachers also has a Free price filter. Check each unit’s listed standards yourself.
Is Defined Learning aligned to Common Core?
Defined Learning says its curriculum is aligned to state and national standards in ELA, math, science, social studies, and computer science, and it can provide alignment documentation for a specific state on request. Ask for that document before purchasing.
Does EL Education cover high school?
No. EL Education’s Language Arts curriculum covers grades K-8. High school teachers will need other sources such as PBLWorks or Defined Learning.
How can I tell if a PBL unit is really aligned to Common Core?
Look for specific standard codes, read each standard on the official Common Core site, confirm students actually do what the standard describes, and check that the rubric assesses each listed standard. A unit with codes on the cover but no matching rubric rows is not truly aligned.
Are Teachers Pay Teachers standards tags reliable?
They are chosen by each seller, not by an independent reviewer. Use them to narrow your search, then confirm alignment by reviewing the preview, the standards page, and the rubric.
