One of Santa's elves had lost the key to the reindeer stable and it was up to the Year 1 children to solve the mystery and free them before Christmas! There were six different maths clues that the children had to solve, each giving them a number. Once all of the clues were solved the numbers revealed the code to open the stable. Luckily, our Year 1 children are so super clever that the reindeer were free in no time and Christmas was saved!
