Someone asked me recently if I had any tips on teaching “estimation with friendly numbers”. I had to admit that I don’t have a magical tip that would instantly help – I’ve struggled to get the same concept through to my own son, after all! However, while framing my reply, it occurred to me why estimation might be difficult for a child who is otherwise good at math.
Math permeates everyday life. It’s a bit cliché to say that, but nonetheless it’s true. It also means that parents can do wonders for a kids’ math education – there are things moms and dads can do that teachers cannot match.
