The world of data sparks to life for students when they engage with numerous high-interest, real-world data sets and construct as well as interpret a variety of graphs. Using personal data about the clothes they wear, the foods they eat, and the hours they spend watching television as well as social data about amusement parks, weather trends, and stock prices, students work individually, in pairs, and in groups to make frequency, bar, circle, and line graphs.
Along the way, they explore graph elements, such as axes, scales, and slope direction. They also encounter three summarizing statistics—mode, mean, and median.
Throughout the series of carefully crafted lessons, students hone their graph/data interpretation skills and ability to connect the narrative story of a situation to its graphic display.
- They begin by making verbal statements about frequencies.
- As the lessons progress, they refine their observations.
- By the close of the unit, students are able to describe a graph or data set with benchmark fractions and percents as well as mean and/or median statistics.
- Concurrently, they develop the capacity to make reasoned arguments and decisions based on data.
- They also learn to question data and graphic representations.
The Teacher Book is an essential component of the EMPower program. It is designed to be used in conjunction with the Student Book. The Teacher Book includes:
- Suggestions for facilitating class discussions
- Open-ended questions designed to keep the math on track
- Math Background sections to help teachers deepen their understanding of a concept
- Lesson in Action sections with examples of student work and comments that illuminate the underlying mathematics
- Examples from the authors' and pilot teachers' classroom experiences
