There's a new site to help make learning fun. It's called
Knowledge Mouse and you can create word search puzzles, flash cards, quiz sheets, math quizzes, etc.
One nice feature which works well with ESL is the ability to make a question-and-answer or "quiz-style" word search puzzle. So you can put the words that appear on the sheet in one language, and the solver has to translate into English and find the English words in the puzzle, or vice versa.
Please give it a try and you can use the feedback fields on the site for any comments or suggestsions. Thanks!
