Hi, I'm a second language English teacher in Liverpool. I have a Polish hearing-impaired learner in my class, who I would like to introduce to BSL, but I know nothing of it myself. I'm going to start her off with the alphabet , if anyone could offer any suggestions for further resources, they'd be very welcome. I'm also wondering if there's any BSL social groups in the Liverpool that I might be able to put her onto? Thanks in advance :-)
