For plenty of other ideas on using Top Trumps in the classroom, especially in Numeracy, check out The Numeracy Shed's Page here.
When you load the app you have to create a username and password, you can then make a top trump by adding a picture, using the camera or choosing from the photo library. Then you can add a title and add three stat and values. It would be great if you could add more, but it is just limited to three currently. There is a range of different backgrounds you can pick from before saving the card to the camera roll.
Here are a few quick ideas, that came to mind when playing with this app:
Why not test children's understanding of a story by asking them to make Top Trump cards for characters in their reading book -
Or use it to review books children have read and have these on hand in class for others to read, or even for a display, would link great with this idea -
