In Poodll WordCards students can add words to their my words list, by tapping on the "+m " symbol.

Free mode can be enabled in the settings for the wordcards activity.

If Free Mode is the only mode available, it will be active already. When Steps mode and free modes are both available a button will appear that allows the user to switch from Steps to Free mode. 

Once in Free Mode the user can choose the word pool to practice from. There are three pools, New words, Seen Words and My words. And the user can choose the practice activity type also.
