Sushi Math

Brother-Bug's all time favorite restaurant is SushiLand - one of those sushi places where we sit next to a conveyor belt and sushi rolls past us in limitless quantities. He tries it all, enjoying some things that I just can't stomach. At our last trip to the sushi restaurant, I realized we had an excellent math game right in front of us.

There are so many possibilities. The plates are 1.00, 1.50, 2.00, and 3.00 each. You pick your plates and the waiter adds up your total at the end of your gorging. On this trip, we kept it simple, just playing with some of the many numbers we encountered.

What to eat next? Tuna? Salmon? Octopus?

I kept my plates in one pile, he kept his in another pile. We estimated who was eating the most by looking at the two piles. At first we tried to keep track of how many of each plate, making hash-marks on our paper...but we got to excited about eating sushi to keep up with that.

It was just too good to track while we were eating...

At the end of our feast, we counted up. How many of each plate? How can we figure out the cost of that stack? Who ate the most? (He did - he out ate me by one plate.) About how much money did we spend? Which plate - 1.00, 2.00 - did we eat most of? Least?

Brother-Bug starts counting. I ate 9 plates. He ate 10. 

It was an awesome math game.

There are so many places it could expand as well. Multiplication, division, quantity of individual rolls...  Mental math as we add up the total... I could give him $15 and he could figure out some budgeting... And going the other way, we kept Sister-Bug involved by having her do some basic counting practice - how many rolls are on this plate? Everyone was really happy, full of sushi, and enjoying finding a new math game out in the world.

Bonus! Sister-Bug works on her fine-motor skills with her chopsticks....

What other things could we do with Sushi Math? I guess we will have to go back...


  1. I love these wonderful and serendipitous moments. Great job all yo Rutledges.

  2. Just to prove that math is everywhere. Just keep your eyes and mouths open!

    Hope you don't mind that I just added a link to The Homeschool Club on Facebook. http://www.facebook.com/homeschool.club

  3. This would be a great outing for my daughter and me. She is a sushi fanatic but still struggles with budgeting and math on the fly.

    The big question is: Where do you go that has good conveyor-belt sushi? I tried Sushi Station once long ago and was found both the quality and freshness lacking. Have you tried the new place in downtown Springfield?

    1. I haven't tried the one in Springfield...but really should. We go to SushiLand in Portland usually. The prices are good, the sushi is good, and it is one of the favorite Portland things we do.

    2. Thanks. Sushi Land is bookmarked for our next Portland adventure!
