Bebras Australia Computational Thinking Challenge
The next round of the BEBRAS Australia computational thinking challenge is occurring over the following weeks for teachers and students from years 3 - 12.
This is similar to challenges such as the Math's Olympiad but is more focused on general problem solving and use of logic. It is completely free and offers amazing data and analytics for students and teachers who are participating.
Above all else Bebras offers highly engaging resources and teaching and learning opportunities which are globally recognised as key components of a 21st century curriculum.
I can't recommend this enough for all teachers and am confident it will become a regular event on your school calendar.
