EDIT: I tried this out today and I would suggest that you allow the children about 2 minutes for each question at least. My G&T year 4s only got 4 questions right out of 12!
Answers uploaded too - sorry for delay!
A picture-board style quiz aimed at gifted and talented year 4 chidlren, (so would work for year 5 and 6 too,) with 12 football/world cup based maths questions.
The presentation is set up so you just have to click on each numbered football to get to the corresponding question. Go back to the number board by clicking the football on each question slide.
