Truth Tables: the Whole Story
Write down every case, and you have proved it

What your child can do at the end
Build a truth table for any circuit with up to four inputs
The brief
Engineers do not test a circuit by trying it a few times and hoping. With two inputs there are only four things that can happen, with three there are eight, and you can simply check them all. That complete list is a truth table, and it is the strongest kind of proof there is in digital logic. In this studio you fill tables by hand, let the studio sweep every combination for you, and compare two circuits row by row.

How it is assessed
3 graded challenges inside the lab, and 8 questions at the end that check the idea rather than the clicks. Every attempt is saved, so a retry after a mistake counts as the learning it is.
