This problem solving game involves children using a range of mathematical skills to get clues. There is a zombie apocalypse beginning in school and pupils need to find the antidote. They will use knowledge of fractions, place value, solve worded problems, multiply, divide, add, subtract and decode a message. Answers and survivor certificates are included. The documents could even be edited to suit a location in your own school for added fun. When I did this with my class, I asked reception to keep a small bottle of green liquid (water and green food colouring) for the children to find. Children can do this activity individually or mixed ability pairs works well. If you like this resource, please give me a review.
