Wii - Day 5

This week Chris and I continued to work off of last week's negative number work with the Wii. On Friday we worked with another game called 30 Great Games Outdoor Fun for the Wii. And yes, while the reviews are not that favorable it did have some redeeming qualities for the classroom. The benchmark we were covering this week was MA.5.A.2.3 - Describe real-world situations using positive and negative integers. The game that we used was called Internal Clock 2. Basically, each person gets a time that they have to count up to. The clock begins counting but after about 5 seconds it goes off and you have to continue to count in your head. When you think you are at the time you push the button. The person closest to the time wins that round. The time is presented in decimal format as seconds, with both tenths and hundredths of seconds. Maybe not the most exciting game around, but the students did like to be able to be faster than the others (and we actually had one student who hit the time dead on). What we did was have them subtract their time from the requested time. The students that hit the button quicker than the requested time were in the NEGATIVE because they were slower than the timer - they still had the amount of time left to get to the correct time. The ones that were over the requested time had to subtract their number from the requested time and they were in the POSITIVE because they were longer than the requested time - they held on too long. For example, during the first round, the student all have to hit the button at 11 seconds. The results were:
  • 10.90
  • 12.45
  • 11.73
  • 11.18
With those numbers, the answer were:
  • -.10
  • 1.45
  • .73
  • .18
In the next round the times are different for each person and in the later rounds the time will change during the actual count up so the students have to pay attention. Also, you can distract the other contestants during the game by waving your controller which causes your person to jump up and down and/or say something. The screen also moves around to other views so you have to make sure you are counting while you are looking at the other things.

Just a couple of pointers:
  1. We created the character the day before we played in the room - this game doesn't use the Mii's so they have to be created and named ahead of time. There are only limited options for looks. Also, there is one girl who could be considered a little inappropriately dressed (has a low cut shirt on).
  2. We found that the students sitting watching the others actually playing started trying to distract the players by yelling out numbers (while the players were trying to count to their number) so we had to nip that in the bud quickly.
  3. We asked the students for other real world situations where negative numbers could be a factor and we got money issues and (with some help from another adult also in the room) sea level.
