The first challenge between teams is about puzzles.

You can create crosswords, wordsearchs, anagrams, etc. using  https://learningapps.org/ 

Once you have done your job, post the link to your game in the corkboard below in your team's column.

Finally you can accept the challenge of other members of your team and solve their puzzle, posting your solution on a file in the corkboard at the bottom of this page.

Here you have to corkboard where you can post the solutions to other people's puzzles. Please, write your name and the name of the people whose puzzle you are solving.
