I just found this post in a window of my computer, unfinished, from last week. Since I wrote this we’ve been to Cincinnati and back, and have done all sorts of other learning. That’s another post, though! 🙂
You know we’re never very traditional, and that includes math. The kids do some math through more conventional means like Khan Academy, Prodigy (a free site that uses Pokemon-style games to teach math concepts) and worksheets, but they also do it in all kinds of not-so-typical ways. Here are a few that we’ve done this week:
- Playing darts: We got an electronic dart board at a thrift store a couple of months ago and it’s been a great source of fun. We typically play 301. You take turns tossing three darts at a time trying to get down to 0 from 301 points. Once you get near zero, if you go over, you bust and your turn is over. You can hit any number between 1 and 20, bulls eye (25) or double bulls eye (50), plus you can get doubles or triples of 1-20. The kids are constantly figuring out what numbers they (or we) need to get exactly the points they have left. For instance, if they are down to 51, they’ll call out “Triple 17!”. Then if someone hits another number instead, they’ll figure out what combinations of darts they can use to still get zero that round from the new number. They’re good at figuring out if there are doubles or triples of anything to get a necessary number, and also of recognizing prime numbers that mean it’s impossible to get to zero that round.
- Mad scientist math: We’ve been doing this for years and did it again in the car yesterday on the way to Mankato. Daryl and I took turns asking the kids weird mad scientist questions (If a mad scientist made cats that had 5 legs and 3 tails each, how many more tails and legs would 3 of his cats have compared to regular cats?) and other oddball questions. Daryl asked Jack a tricky question about battling a hydra — if every time you cut off one of its heads it grows two back, how many heads will it have after x many times you’ve chopped its heads off? We also did lots of Vikings football player volume ones (how many can you fit in a swimming pool and such, like these at Magical Homeschool). The kids love them and they really get them thinking about complex math.
- Foraging: You know we do a lot of foraging as a family and math even comes into play there. Daryl and the kids gather asparagus just about every day in May and they always weigh it (along with everything else we forage) to keep a running total of our harvests on the fridge. The kids tend to hold the bag and estimate the weight before weighing it on the kitchen scale. They’re getting very good at estimating weights. Then they add that total on to the last tally. (In case you’re curious, we’re at just over 25 pounds now and here’s how we find wild asparagus in different seasons). Also foraged so far in May — morels, pheasant back mushrooms, oyster mushrooms, violets (violet liqueur is steeping now), waterleaf, ramps and probably a few I’ve forgotten.
- Walking math: When I go on walks with Alex, I make up math questions as we go along. For instance, I’ll ask him what 1/4 of 300 is, or ask him how much a shirt would cost if it was 90% off and it was originally $18. I also ask him spelling questions, and do the same thing with Jack while I’m driving with him. There is also a lot of time we just spend chatting, but it’s a nice way to sneak in some homeschool. Yes, I am that homeschool mom. 😉
- Helping the neighbor: We have a new neighbor next door to us and she was trimming her trees the other day. Alex, Jack and Fiona gathered to help her trim and haul the branches, and she thanked them for all their work. After they were done, she got out a big coffee can of change the last owners had left and divided it among them. Fiona got mostly pennies but still had over $3, and Jack had over $7 and she told him he owed her an hour of work sometime for the extra (Alex didn’t tell me his total). The older kids helped Fiona count her change, and they all started making plans for how much they would spend on what. The boys are constantly torn about spending their money or saving it up for better things. Jack has been wanting to save up for a Wii U but it’s a daunting amount of money. Alex wants to buy a 3D printer and I told him that I’d chip in $100 if he and any of his siblings could gather the rest. He gets $15 a month allowance and Jack gets $30, so he was figuring out how long it would take them with my contribution if he was the only one saving, if Jack helped, and so on…
