We have been studying probability for the last week. We learned about events. Our Math Coach came in and did two lessons. We learned about probability by doing a coin toss. We know that there are two possible outcomes in a coin toss; heads or tails. We recorded our data on a T chart using tally marks. We also did a survey on choosing a favorite number (1,2,3, or 4). At first we only surveyed our classmates. For homework we asked our family and friends. Once we collected the data we recorded and represented the data using a horizontal bar graph. Mr. R followed up on this lesson by having us survey other third grade classrooms, it was Mrs. Carillo’s Idea – our Math Coach
Here are the results;

I like your graph! There are three main kinds of graphs people use: pie or circle graphs, bar graphs, and scatter plots. Which one is this third grade?

This is a horizontal bar graph. by DT

Wow! Great job in cllecting the data. After gathering the data from a larger sample group what can we infer about it? How if at all was the data different from the data gathered from just room 36?
Something to think about:
If you were going to print up T-shirts which number would you print up the most and why? How does the data support your decision?
