Take On The Teacher! is a spelling game from Scholastic in the United Kingdom. You’re shown two words and have to pick the one that is spelled correctly.
It’s a fun little game, though if you’re in the United States there might be a few trick British ways the British spell their words. Unfortunately, the words are not actually pronounced, which limits its use with English Language Learners. There are, however, cute sound effects when you choose the correct word.
I’ve placed the link on my website under Spelling.
