To: thingumbob; MileHi; LittleLinda; numberonepal; generally; Farcesensitive; Keflavik76; DrewsMum

16 was the correct answer

*********************************************

NO. None of the given answer choices is correct.

2 + 2 x 4 = 10

WHY?

Let’s suppose:

Thingumbob, MileHi, LittleLinda, and Numberonepal each measure the dimensions (length and width) of the same room.

Thingumbob determines that the room’s length is about 17 feet and the width is about 11 feet.

MileHi determines that the room’s length is about 21 feet and the width is about 14 feet.

LittleLinda and Numberonepal both determine the length to be about 23 feet and the width to be about 15 feet.

Why are their measurements different?

Thingumbob and MileHi determined the length and width of the room by each placing his feet heel-to-toe to while walking and counting the number of steps taken for the measurements. (For this scenario, Thingumbob - 1 foot = 9 inches; MileHi - 1 foot = 11 inches.)

LittleLinda and Numberonepal determined the length and width of the room by using a standard measuring tape (1 foot = 12 inches).

LittleLinda and Numberonepal understand that we agree to use the same units of measurement AND the order of operations when communicating with one another.

(Note: For better understanding of the process, I would change the last two steps. Instead of using the word “and,” I use “OR, whichever comes first, left to right.”)

I watched your Math Antics Order of Operations video after you posted the link. I imagine your students would have found it to be very entertaining as well as instructive. You must have been a very good teacher to be so imaginative in your lessons. Math can be dry, though I never found it to be so.
