Data Management lessons in Chiang Mai

When we travel during the school year we bring our homework. Even though I believe the best learning happens just by traveling, I also feel it is really good to keep up. So I get the pleasure of helping Lucas with his grade 6 data management math curriculum (and I do find it a pleasure).

Lucas and I have been working on his graphing and xy number pairs, etc for 10 days now. He really gets it, a couple of days ago I drew a Christmas star on a piece of graph paper, he correctly identified, and documented, all the number pairs for the star. Then I gave him the monthly rainfall totals for Chiang Mai, St. John's, and Vancouver as monthly number pairs. He correctly identified the scales and intervals, and drew a graph comparing all three cities rainfall.

Today's activity was to count the number of different vehicles traveling through a busy intersection. Our count was set by two minute intervals.

These are our results; we only counted tuktuks, motor bikes, and songtows.

When I asked Lucas what predictions he could make, he said the following;

• We could see 8 - 15 songtows every 2 minutes
• We could see 3 - 10 tuktuks every 2 minutes
• We could see up to 75 motor bikes every 2 minutes
• I said there seems to be a relationship between motor bikes and tuktuks. The more bikes the less tuktuks and vice-versa. But we need to collect more data to prove this.
