Pro tip — heads up before you bookmark it
Free content can move or disappear
ESL Base is run as part of a TEFL business — when the company pivots or rebrands, free pages sometimes get restructured or removed. Download the worksheets and flashcards you actually use, rather than relying on bookmarks.
What is ESL Base?
ESL Base (eslbase.com/teaching) is the free teaching-resources arm of a TEFL business that also runs paid certification courses and a language-school directory. The teaching section is a curated hub of practical materials for classroom teachers rather than a polished editorial publication.
The site is organised into clear sections:
- Downloadable Activities — printable worksheets and lesson plans organised by skill
- ESL Flashcards — free, professionally designed flashcards in PDF
- English Grammar — explanations plus a short online course
- Ideas, Techniques and Activities — short articles with classroom tactics
- Teaching Online — tips and resources for the online-ESL market
- TEFL A–Z — a glossary of terms, methodology and approaches
- Young Learners and Business English — two audience-specific verticals
Design-wise it sits somewhere between an old-school TEFL blog and a modern resource library. Nothing flashy, but the navigation is clear and the materials are practical.
How teachers use it
ESL Base works best for these specific teacher tasks:
- Last-minute lesson plans: when you have 10 minutes before class and need a printable worksheet fast.
- Flashcard printing: the free flashcard packs are professionally designed and print clean — useful when you want to skip the DIY PowerPoint.
- Grammar refreshers: the grammar section explains common pain points (articles, conditionals, tense mixing) in plain English with short examples.
- Trainee teachers: the TEFL A–Z glossary is a fast way for new teachers to learn the terminology they'll hear in trainings.
- Online-teaching prep: the Teaching Online section curates tips specific to platforms like Preply, iTalki, and Cambly.
- Job hunting: the language-school directory and job board (linked from the main site) make this a useful combined hub.
Is it worth your time?
Yes — for the price. ESL Base's teaching resources are genuinely free and cover most of what a working teacher needs on a daily basis. You're not getting massive searchable libraries like Ellii or ESL Brains, but you don't need a subscription either.
The trade-off is depth: lesson plans tend to be standalone activities rather than full unit sequences. Pair ESL Base with one of the alternatives below if you teach structured curriculum tracks (Crystal Clear ESL or ESL Brains) or want more printable variety (Teach-This).
Honest recommendation: bookmark ESL Base as a "first-look" resource when planning a lesson. If you find a grammar explanation or a flashcard pack you like, save it locally — content on free TEFL sites can disappear when the business pivots.
