Procreate is, hands down, one of the most powerful iPad programs out there — but I've never been able to use it for
simple sketching because its complex array of brushes had just a tad too much latency for me to feel comfortable with them.
We gave the students, right from the word go, a very
simple engineering model of: Look at the problem, brainstorm — think about some ideas, draw some initial designs (and we get the children to
sketch those)-- but what we've also brought in is some experiment as well
because children will be using the hands - on materials and they love to experiment.
