Crosswords are a great way to test or review vocabulary. However, if your learners are a little more able, half-crosswords are easier to prepare and more challenging for your learners.
Half-crosswords are tricky to create, but luckily the website halfacrossword.com offers an extremely easy way to put these together.
To use the crossword, pre-teach the vocabulary items then put learners into pairs and give each pair their half of the crossword. They take it in turns to ask for a word that fills the gap in their puzzle (don’t forget to pre-teach down and across!). Of course their partner can’t just give them the missing word they have to find a way to describe it to their partner.
