Math contest results are almost out. We are waiting for one more class’ result to finalize the final winners. We know at least two of students in our class are winners.

We start the 2nd half of the spring semester with focus on statistics, the science about collection and representing data and how to read and draw different graphs.

We first introduce different ways to represent data: bar graph, pie chart, line graph, and pictogram graph. We talk about the pros and cons of each approach.

We then talk about how to read and draw bar charts.

With the extra time left, we talked about a few questions from math contest.

Homework:

P130. #3, 4, 10, 11, 12
