TextActivities is a great tool for practising translation into the L2 / the target language.
You can create your own resources in a matter of minutes and then have access to all sorts of activity options that will give your students TONS of translation practice.
Getting your students used to doing this sort of thing from the get-go can only help to improve their ability to write accurately in the L2, including translation, and arguably the sorts of noticing and implicit grammar practice involved in these tasks will make them more competent speakers of the L2 as well.
(The activities generated can also include audio, so dictation and listening practice are also available. But this post focuses solely on activities with an L1 prompt that require students to translate that prompt into the target language.)
