Today is International Creativity and Innovation Day when we celebrate problem-solving in the context of economic, social and sustainable development. The purpose for World Creativity and Innovation Day is to remind and encourage people to use their creativity to make the world a better place and to make their place in the world better too.

21st April, the day before Earth Day (22nd April), was chosen as World Creativity and Innovation Day to emphasize the importance of using new thinking to create a decent life for all on a sustainable planet.

I have attached a word problem relating to the invention of hopscotch.
