Arcademic Skill Builders
Arcademic Skill Builders is a fantastic website for ESOL and numeracy learners. The site contains a variety of games that enable learners to practise maths and English. What’s great about the games is that learners can play against each other by creating a private room that others can join if they know the password.
Examples of games include Kangaroo Hop for shape recognition, Spelling Bees, Jet Ski Addition, Giraffe Karts for practising subject-verb agreement, Elephant Feed for practising synonyms and Grand Prix Multiplication.
The only thing to bear in mind is that the site uses American English, but I didn’t find this to be a real problem even for the spelling games.
