In this 2-part activity students will create line graphs based on real world data, average monthly temperatures from various countries. Students will start with a probing question of "how does the temperature of the US compare to other countries?". Students will then as "international weatherman" be assigned a country to create a report that includes a line graph showing their data along with questions/answers that on day 2 the rest of the class will answer in the around the room task card activity. Their graphs they create will be used as the task cards along with their questions.
The lesson can be differentiated to include students rounding decimal numbers to the nearest whole number, creating single/double/triple line graphs, developing questions that could go into mean, median, mode, range. There are multiple possibilities, and all of the materials needed to supplement the lesson are available to students.
There is an example graph of the average temperature data for the US (single, double, and triple graphs) students can use and can analyze to understand what a good quality graph needs to include (titles, even spacing on axis, key, etc.)
