I always create my own flashcards, depending on the student profile. Since I teach an integrated class of mixed abilities, it makes more sense. I usually download images off websites that boast of free printables and worksheets. Sometimes I find them on pinterest which is another great source for resources and then I customize them on Word or PowerPoint. I get my
cool math based English flashcards off the printables on the Math Blaster Website. Etsy has some handcrafted ones but they're really expensive. Where do you stay? Maybe that'll help us list resources close to your place.
