### Wii - Day 6

Today we finished up with the same game that we used the last time we pulled out the Wii, Internal Clock. We wanted to make sure that all of the students who didn't get a chance to play last time (we just ran out of time) were all able to have a remote and try to keep time in their heads. Before we began Chris orally went over what we did last time and had the students answer questions about what operation we were using (subtraction) what the difference was between the negative and positive numbers, and seconds and milliseconds vocabulary. We brought the students up again 4 at a time and had them use the same people that were created last week (all of that same work was already there from the last time we created them all). This time we decided to concentrate on the 2nd of the 4 rounds that the game plays. During the 2nd round each of the 4 players have a different time they are trying to get the closest to so it means 4 different math problems. We put the students name on the board and put the times they were trying to hit and had all of the students write down the same info in their Math copybooks. Then the 4 began playing. At the second round we had this:

Player - Total time - Time recorded

1 16 18:18 2:18 over

2 21 25:81 4:81 over

3 22 30:78 8:78 over

4 20 20:80 :80 over

After the times were posted on the board, Chris asked the questions - Was anybody under time? Was anybody over time? Would that be positive or negative numbers? Who came the closest to the time they were trying to hit? Then the students all had to do the Math problems and tell us how far over they each were from the target time. After we checked a few answers the students were able to finish round 3 and 4 and declare a winner for that group. We switched the group of 4 and began again.

The procedure was the same, but this time the results and the questions we asked were a little different:

Player - Total time - Time recorded

1 16 15.81 .19 under (-)

2 18 18.96 .96 over (+)

3 23 17.15 5.85 under (-)

4 15 17.51 2.51 over(+)

Again, we asked the same questions but added the directions to now put the recorded time in order to closest to target time to furthest away from target time (not making a difference for positive or negative numbers).

Then we asked the students to put the results in order from least to greatest. Now they had to take the negative and positive numbers into account when they placed it in order. This was a bit of a review from the last game we played with them on Big Brain Academy which was popping the balloons in order from least to greatest. Again, we checked a few and moved on to let the students finish the game. We switched out the kids two more times having them take down the numbers for the 2nd round each time and doing the Math. We made only one slight change during the last round which was a bit of a bump in the road. During the last round Chris asked the students to order the numbers not from least to greatest, but from greatest to least. We had 4 different students who said it was harder for them to group them that way then it was to group from least to greatest. After we went around and made sure that we were all together we let the students finish up the round and then have the last groups go. We worked out the Math problems and answered the questions after the 2nd round again. By the time we were finished each of the students had played the game (either this week or last) and they all had at least 15 math problems completed.

A few notes:

1. In an effort to give all the information, today was the first day of our Spring Break. We did have school, but it was only a half day - students out at Noon. So, the group was a little more wound up then usual. Not a surprise for anybody who works with students! All in all they did a good job working the Math problems, but it did take a couple of reminders from Chris that all of the students should be doing the Math work at their desk, not just the people that were playing.

2. We asked the students why they thought it was more difficult to go from greatest to least instead of least to greatest and while we didn't really get a complete answer, a couple of students just said it was easier to start with the negative numbers and move up to the positive ones...

3. One or two of the students made the observation that if you were having a problem with the greatest to least ordering, just do least to greatest and reverse it. This helped some of the confused students, but not all.

In future posts, I will make an effort to see if we can get some screen shots of the games and the math problems that we are completing during the process!
