I've been thinking about selling workshops/lessons on either TPT or TES (or possibly Etsy?) as I have a huge collection of ones I've created (and delivered) for ESL primary-aged children over the years. They're all organised by topic, with materials needed, prep instructions, SEN considerations, learning outcomes/aims etc just ready to print and use.
Would this be something that would sell? I've occasionally downloaded resources myself, but the quality has been mixed, which is why I've usually resorted to creating my own. DeepSpaceSparkle has some fabulous art lessons that I've used as-is, but the ESL sites are often very disappointing.
Any thoughts or advice very appreciated!
