I can work with my class to collect data.
I can use a meter stick to measure a person’s arm span and their height.
I can organize data using a table.
I can create a properly labeled coordinate graph.
I can draw a line through the points which represent a person’s height is equal to a person’s arm span.
I can explain the meaning of data which lies on, below, or above the line drawn through the points where the arm span of a person is equal to the height of the person.
