Questions such as 2374 + ______ = 5763 and 6392 - _____ = 2847 in a domino style format for children to work out and match together.

Resource regenerates with different numbers if you press f9 or reopen the file, hence you could make an infinite number of different puzzles!

I make the resource on coloured card and find that they can be reused many times over - or laminate if they are going to be regularly used.

Thanks for looking.
