"We don't skip teaching the English language to toddlers in favor of a simpler one." Well, they used to for a bit in the UK https://en.wikipedia.org/wiki/Initial_Teaching_Alphabet https://en.wikipedia.org/wiki/Initial_Teaching_Alphabet as a result of which I still (5 decades later) sometimes have to stop and think about the spelling of quite routine words. So I agree - toddlers get a subset with a restricted vocabulary and simple grammar but one that is actually a subset of English. Now - if I wanted to learn enough Javascript/CSS/Canvas stuff to make a series of 'drag-gable diagrams' for use on an interactive whiteboard (e.g. area of trapezium or pythagoras' result) where shall I start? I have the head first book and I sort of like their approach.
