 The Project TIAN mathematical content centers on two strands of mathematical proficiency: algebra and data. Participating teachers and their students learn by investigating the patterns and mathematical information found in real-life situations.

### Learning Goals for Students and Teachers

#### Data and Graphs

• Collect, organize, and represent data
• Make accurate statements about data using percents and fractions
• Create and interpret frequency graphs, bar graphs, circle graphs, and line graphs
• Make predictions, decisions, and recommendations from information presented in bar, line, and circle graphs
• Use scale to change the story a graph tells
• Interpret graphs with different scales
• Use mean and median to describe a data set

#### Algebraic Thinking

• Identify patterns and predict outcomes in a variety of situations
• Describe patterns and relationships using a variety of representational tools: diagrams, words, tables, graphs, and/or equations
• Understand how the different representations are related
• Recognize the characteristics of linear patterns
• Use and understand basic algebraic notation
