During the night, someone sneaked into school and stole something precious belonging to each of the year 4 teachers and locked it away in a box. The only way for the children to retrieve these items for their teachers was to solve a series of maths problems to get a 10-digit keypad code which would unlock the box!

All classes loved working hard for their teacher to get the items back and were delighted to return Mr Coleman's Arsenal cushion, Mrs Danson's glass penguin, Miss Lewis' Cadbury's Creme Egg and Mr White's guinea pigs!
