This year’s Christmaths Advent Calendar will have a question for every day in December up to and including Christmas Day, each one featuring a new mathematical challenge.
As he sets out on his journey to deliver presents to children around the world Father Christmas goes through a starry part of the sky collecting stars to scatter nearer the earth.
He has a plan of the area, which is like a grid. Each square of the grid shows the number of stars he could collect.
Father Christmas can travel horizontally, vertically or diagonally through the stars.
- What is the smallest/largest number of stars Father Christmas could collect?
- How many stars are there in the shortest route/the longest route?
- Is there a way to collect exactly 100 stars?
- Are there two different ways where he could collect the same number of stars?
