Flash is a dead technology in schools. It's a complete waste of time.
Teaching kids to program in flash is the new Latin.
School technology leaders may throw up their arms aghast and shout, 'but we need it, we rely on it, our kids use it every day' but seriously, flash is dead.
It's a hacker's delight.
Use it like any other old bit of kit, talk about it in the past tense. Kids will 'ooh' and 'ahh' when they see those little blocks on the screen move around with various keyboard presses or mouse moves. But face it, Flash is dead.
