The best way to get kids interested in math and the sciences in general is to show them how those disciplines are used to solve real problems, such as using flow rates of runoff and residence times in retention ponds below to calculate times and severities of flooding over the tops of the retention ponds, for urban planning, and showing the kids how the ancients measured (geometry) and mapped the earth according to its axial precession rate of 72 years/degree, how the ancients established the length of the royal cubit, and the olympic foot (the base 60 template of which was the forerunner of our modern nautical mile mapping system of arc minutes and arc seconds).
