Big idea:
Observation and description of changes in the world around us are the first steps in discovering patterns.

Essential question

 * What are some of the variables around us?

Mathematical Reflection pg 17.

1.The two variable on the table and graph is 1) Number of jumping jacks. 2) Time (seconds). Every 10 second the jumping jacks always increased.

2A. Some things that vary in the would around us is stars, temperature, number of cars that pass the road, the amount of rain that falls and population growth. I think that two variables that would be related is temperature and time.

B. I would make a graph by showing how the temperature changes throughout the months during the year. I assume that the time always goes to the x-axis because so that you read the graph from left to right. I will put the weather on the y-axis
