Reassure the teacher that she is doing the work. Reassure your dd that you will help her.
If the teacher is setting them 10 words a lesson to learn, then help your dd to break it down. Get her to learn 6 words. 5/6 is better than 2/10 and will help to boost her confidence. If the teacher points out that it is only 5/10, it is still better than 2/10.
If she is having to learn bigger amounts - 50 words a week say - then help her to put the words into sentences, and memorise whole sentences. So instead of learning blue, red, dog, house, sit, you learn the blue dog sits on the red house.
DS was in the same situation last year. In terms of his mock exams, I helped him to remember half a dozen sentences on each topic. There are certain questions, certain topics which always come up, so look through a past paper, and help her to learn sentences to answer those. Eg there is nearly always a letter/email to write to a penpal who is going to visit you as part of an exchange programme.
eg Tell your penpal what they are going to see in your home town. "In my town there are two parks, an old church and a museum. There is a leisure centre near to my house, and football stadium. I played football when I was quite small - about 10 years old. It made me happy. " (Always aim to include a past tense; a qualifier (very, quite; and an opinion.)
There is nearly always a question about holidays - what did you do on your favourite holiday? Where will you go next year?
Even better, she doesn't need to make the answers up. Look at her text book. There will be whole sentences there that she can simply copy and learn. It isn't cheating to say "I love Paris. I visited this historic city last year, and saw the Eiffel Tower. It is very large!"
