My kids are doubling not by multiplication but by addition. It is what they do for fun. Do they know about calculators? Yeah, but calculators don’t allow this many numerals on a screen anyway. Do they know that someone else has probably already done all this doubling? Maybe not, but if they thought about it, they would probably think it is probable. They do not care. This is something they are crazy over. They love doing it.
Do they know that multiplying may be faster? Beats me. This is creative, Constance Kamii math. She would say, let them at it and let them figure things out their own way.
So what does the homeschool mom think? She thinks, “Oh, YEAAAAAHHHH!” I think it is awesome. I bask in it like the emperor penguins bask in the sunlight after a long, cold, windy winter.
They are on day sixty of doubling the mini m&m’s you’d have to eat if you doubled the number daily. For 60, they have a figure of 1,146,582,183,045,318,976. I do not know if that is accurate, but that is what they have.
