Promethean Processing

In part one of this lesson, you will learn about Promethean thinking and the four-step problem-solving cycle. You will then be challenged to model a standard six-sided die, before breaking it down into nine cuboid components. But the challenge doesn’t end there! In part two of the lesson, you will be challenged to reassemble your die from its components, firstly on instinct, and secondly by following the problem-solving cycle. Once you have successfully reassembled your own die, it’s time to swap with your classmates and see who is the quickest in the class!
