Some ESL Learners need to practice consonant blends in English. This is often because clusters (2 or more consonants together) are not in their first language. Vietnamese is a good example of this. So land sounds like lan, and pint sounds like pine.
I love this online resource that has many free printable lists: locotour.com
I have used their lists for R remediation and to treat lisps, by using their lists for S, Z, SH, ZH etc.
Recently I went back to their word/sentence lists to help a client who was learning English as a second language and needed help making her accent sound more American. Click on the links here and see the free printables for some helpful word/sentence lists! Keep up the good work teaching English.
