Road Trip – MEL3E Day 9

Today’s warm up we played the game of NIM. I started this off by saying “I’m the undisputed champion of Southern Ontario on the game we’re going to play. I’ll give $10 to any player who beats me!!” I put down the bill on the table!

Game of NIM in our classroom:

There are two players. There are 21 sticks in a pile. Players take turns. A player can choose to take 1 or 2 or 3 sticks from the pile. The player that takes the last sticks wins!

Easy enough game? My students thought so and were eager to win $10. I played 2 rounds each with a different student in front of the class. They couldn’t believe that I had won both times at such an easy game. I let them in on the secret so they could go off and play and win against their friends or parents.


If you can leave your opponent with a multiple of 4 …you win….so with 21 sticks you can always win if you go first.

Next up we are switching strands to Travel and Transportation. I started with having them split their whiteboard down the middle. On one half they wrote “I notice”. On the other side they wrote the heading “I wonder”.

I showed this short clip and asked them to write down anything they noticed and anything they wondered.

I gave them 2-3 minutes to write down their noticings and wonderings. Next they had 2 minutes to share that with their partners. Then they shared with the group. At first they were pretty shy to share with the group….but once we got rolling…….they wondered a lot!!

I explained that the “oh no” in the video was said because driving to SF looked super long! We had a great lengthy discussion about travelling by car. A few stories from me and also from them! The list of wonderings they generated will fuel our work for this part of the course! We will come back to driving costs and owning a vehicle costs next cycle…..this time around we’re going look at travelling by Air, Bus, Train. We’ll read schedules, learn about time zones, and read 24 hour clocks.

Today’s focus –and as it turns out Monday’s too– was on air flight. We broke out the iPads and looked up flights to SF. I handed out a recording sheet.


Most students hadn’t searched sites like Expedia or Travelocity before so we went slowly. We’ll resume this activity on Monday and we may get to doing some problems with the World Clock and the 24 hour clock.


2 weeks done! Happy Friday!
