Hundreds of schools in Israel are using Moodle. I guess there are many English teachers who do so with their pupils. Teachers may not know, or may not have tried a good option to review vocabulary that Moodle provides: Moodle games. Here is one way to take advantage of that
1. Create a Glossary (a Moodle resource) with the words you want pupils to review.
2. Create at least three different games based on that Glossary.
3. "Play" the game with the class (use a projector).
4. Tell kids to review vocabulary playing the games at home (hopefully they might do it).
You see, you do not need to "hunt" for many tools to do all this
