I use these lessons for learners at A2 to B2 levels (depending on their needs, level of support and time available), but you know your students best, so use your judgement over whether the level is suitable or needs adapting.
This is a lesson to present and practise the sounds sss, zzz and shhh which can be a problem for most nationalities.
Short vowels: a, e, i, o and u or / æ e ɪ ɒ ʌ /
A short lesson plan to practise short vowel sounds (works well as a 15 minute filler in a longer lesson). It looks simple, but often the difference between /æ/ and /e/ or /æ/ and /ʌ/ cause problems (not to mention /t/ and /d/ at the ends of words, and /ɪ/ mispronounced as /i:/).
Long vowels: a, e, i, o and u or / eɪ i: ɑɪ əʊ ju: /
This is a short lesson plan to practise long vowel sounds (magic 'e').
Er, or and ah or /ɜ:/ /ɔ:/ and /ɑ:/
These are activities to introduce "er", "or" and "ah" sounds, with spelling hints and lots of follow-on practice. You could also try this big crossword (quite time consuming) or small crossword puzzle (if you have limited time) as follow-on practice.
Ear and Air pronunciation or /ɪə/ and /eə/
This is a handout to practise the /ɪə/ and /eə/ sounds.
This is a lesson plan to present and practise the /tʃ/, /ʃ/ and /k/ pronunciation of the letters 'ch' at lower and upper levels. Don't be fooled - I thought my students would find the snap game childish, but it was actually quite challenging and they responded really well to it!
This is a maze to encourage students to distinguish between the sounds for words with 'ou', 'o' and 'u' spelling.
This is a lesson plan to present and practise seven differents ways to pronounce the letters 'ea'. I would suggest simplifying it considerably if you plan to use it below B1 level! As a warmer, you get students to brainstorm words spelt with 'ea' (give them a point for each word they got that no one else did, or do a 'last-man-standing' kind of game where they have to sit down if they can't think of a word).
There is also a dominoes game here (it's quite challenging, even for good B1 level students) which you could try as a follow-on (perhaps as a review on another day).
This is a worksheet to practise identifying and distinguishing between the spellings of 16 common homophones
This is a pyramid jigsaw to test vowel sounds with confusing spellings (such as hurt and bird). British accents vary quite widely in their pronunciation of vowels (this puzzle is just for RP) so with higher levels you could discuss how pronunciation might change with region (e.g. laugh could be like heart or hat depending on where you come from). Answers are here.
