Many resources are unfortunately only kl-da, or da-kl. I haven't yet seen en-kl, or kl-en in schools, or anywhere. But I know there is an old app for android that goes kl-da, and da-kl. It is meant for greenlandic students learning danish. If you still know your danish, you can use the app to translate words.
There's also a website(again, danish to greenlandic, and vice versa).
The reason there's no much resources in English is because Denmark handles all foreign affairs, so Greenlands way to the world is Denmark.
I hate the fact there are 3 subreddits for learning greenlandic, /r/Greenlandic, /r/kalaallisut, and /r/LearnGreenlandic, and they all seem to be dead.
