Mathematics - 4th Grade

• Categorical and Numerical Data
  Students will compare representations for categorical and numerical data.
• Collecting, Representing, and Interpreting Data Using Spreadsheets and Graphing Software
  Spreadsheets and graphing software are tools for organizing, representing, and comparing data. This activity illustrates how weather data can be collected and examined using these tools.
• National Population Projections
  Students will examine the United States Census Bureau website to investigate population projections from 1990-2100. Using the five provided pyramids, students will analyze the data to determine how the population is distributed over time, and explain what factors might contribute to these trends.
• State Population Projections
  Students will examine the United States Census Bureau website to investigate projections of the total population of states from 1995-2025. Using the provided data, students will analyze statistics from five states of their choice, develop specific research questions using the data, and create three graphs to compare and contrast the information.
• Uncertainty
  Students will analyze collections of both their own data and others. Students will create data distributions in order to determine the highest, lowest, and middle values, as well as pile ups and gaps, for a particular set of data. Students will also be introduced to the notion of sample size and how it can affect results. Finally, students will begin to explore the questions that can be answered based on a set of data, and the additional questions it might prompt one to ask.
• Working With Categorical Data
  Students will formulate and refine questions which can be addressed with categorical data. They will consider aspects of data collection such as how to word questions and how to record the data they collect. Finally they will represent and analyze the data in order to answer the question posed.
