Math is the description of the possible. We apply a bit of this and a bit of that to see if it works. When it does, everyone rushes out to duplicate it. As a team, we simply studied the experts to find out why it was impossible, then found a different way. No sense in repeating what didn't work for others.
Every child wants to know and do it all.
We don't know how to do that. We can teach you how to discover a way to do it. True scientists never stop. The science methodology should be the context about which all curriculum is taught. The primary children are taught to work together to explore the world around them and explain what they find.
