Two things have to happen to change how many cards appear in the field for each of the activities on the Language Builder Pro App and the Language Builder Basic App:
1. you have to choose the number of cards you want to see in a field. 2 cards will give you one Target Card and one Distractor Card, 3 cards will give you one Target Card and two Distractor Cards, 4 give you one Target Card and three Distractor Cards, etc. But ONLY if ...
2. you select the minimum number of Distractor Cards you will need to make out the field. If you select 2 cards for the field, you have to select 1 or more Distractor Cards, 3 cards for the field 2 or more Distractor Cards, etc.
If you select 4 cards for the field and only 1 Distractor is selected, then only 2 cards wil show up. If you select 4 cards for the field and 3 distractor cards, then it will always use the same 3 distractors. If you select 4 cards for the field and more than 3 distractor cards, then it will rotate among the distractor cards you have set.
