This month's challenge is a little different than previous months'. It is based on the Hour of Code! The challenge is to have every student in your classroom complete at least an Hour of Code in the month of December.
The Hour of Code initiative takes place each year during Computer Science Education Week, which is December 9-15. You can experience this at any time of the year, though! It is held annually in recognition of the birthday of computing pioneer Admiral Grace Murray Hopper (December 9, 1906).
The Hour of Code started as a one-hour introduction to computer science, designed to demystify "code", to show that anybody can learn the basics, and to broaden participation in the field of computer science. It has since become a worldwide effort to celebrate computer science, starting with 1-hour coding activities but expanding to all sorts of community efforts.
