The Data Analysis Unit involves using a variety of ways to organize data in order to answer questions such as:

• Why does your display best represent the information you collected?

• What kind of data can be displayed in a stem-and-leaf plot?

• Why is a key useful for interpreting data in a stem-and-leaf plot, line plot or frequency table?

• What kind of data can be displayed better in a line plot than in a stem-and-leaf plot? Why?

The Measurement Unit involves strong connections between attributes that can be measured (distance, time, capacity, mass, and area), formula building (algebraic reasoning), and the four operations. Questions to answer may include:

The Angle Measurement Unit connects measurement to geometry in order to answer questions such as:
