๐ Topic Summary
Coordinate planes are like maps for numbers! They help us organize and understand data by showing the relationship between two sets of numbers. Imagine a graph where you can plot points - each point represents a piece of information. In fifth grade, we'll learn how to read and interpret these graphs, focusing on identifying points and understanding what they tell us about the data.
Data analysis on a coordinate plane involves looking at the plotted points to find patterns, trends, and relationships within the data. It's like detective work, but with numbers and graphs! We use the x-axis and y-axis to locate each point, and then think about what the arrangement of those points means.

๐ Part B: Fill in the Blanks
A coordinate plane is formed by two number lines: the _______ and the _______. Each point on the plane is represented by an _______ which tells us its location. The point (0,0) is called the _______. We use coordinate planes to represent and analyze _______.
๐ค Part C: Critical Thinking
Imagine you're tracking the daily high temperature for a week on a coordinate plane. The x-axis represents the day of the week, and the y-axis represents the temperature. How would you describe a trend where the temperature consistently increases throughout the week?
