Time Is Math

One of the disadvantages in teaching in my part of Alaska was that when spring finally rolled around, most of the boys — and some of the girls — would prefer to be out on the tundra shooting at the amazing plethora of recently-arrived ducks, geese, and cranes — and hopefully not shooting any swans!

Because hunting was a skill that was very important to the Yup’ik culture — and useful, too — I understood that they were learning some practical skills even outside my classroom. But on the other hand, if I reported too many absences, I’d be catching some flack from our district admins.

So, on whatever day that class attendance had dropped unacceptably low, I’d announce a lesson in ”money math.”

Some background info: over the course of that year, my students had been very active in fundraising, mainly showing movies for the village multiple days each week, at which we also sold a lot of popcorn, drinks, and homemade “ice pops.” So, by the end of the year, we had a lot of buckets full of coins. This money would usually follow them to the next higher grade the following year, but unfortunately, my predecessor had taken his classes’ money with him when he’d left the village two years earlier. To prevent that from happening again and to give my attending students some “real-life” math practice, I’d bring out one of the coin buckets and place a big handful of coins in front of each pair of “money math” partners.

They would then need to sort them into appropriate piles — quarters, dimes, nickels, and pennies — and then use multiplication to find the total value of each type of coin — e.g. “7 quarters x 25 cents each = $1.75.” Then, each pair would need to add all of their total coin values together and write that amount in a list up on the blackboard. As a class, we then needed to add all of those amounts into a grand total of all the handed-out money for the day. And last, we needed to do on the board the most difficult division problem we’d ever done in order to figure out how much each student would be getting — and later giving them some additional practice at counting out their “shares.”

Hey, who says math needs to be boring?

As a pleasant, and very planned-upon consequence, attendance the following day would almost always be at or near 100%… even though “money math” was almost never offered two days in a row. I guess just the possibility that they might be missing out on a “money math” lesson gave them some extra motivation to not skip.
