What you have experienced will influence how you filter and interpret things.
Here is an object lesson to teach this concept.
Ask your students what is the worth of two dimes?
They will say 20 cents, as this is the worth of today’s dimes. But here’s the twist. But here’s an alternative view. Two dimes from the years of 1854 to 1964 contained 90% silver and were at that time worth 20 cents. Those two dimes minted then were 20 cents but today their actual worth, because of their silver content, is now worth $2.93.
Use this as an example of a paradigm.
