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.
Start on any of the bottom seven baubles and make your way to the star at the top of the tree.
Move from one triangle to the next by crossing a side, adding up the numbers in each triangle you visit.
- Can you find a route to the star which adds to 100?
- Can you find a route which gives the lowest possible total?
- What is the largest total you can make passing through only 15 triangles?
