Grade 4 - Data Analysis Unit
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?
Math Concepts and Skills:
The student solves problems by collecting, organizing, displaying, and interpreting data.
The student:
- represents data in a frequency table, line plot, or stem-and-leaf plot with whole number and fraction intervals.
- creates and solves one- and two-step problems using data in whole number, decimal, and fraction form in a frequency table, line plot, or stem-and-leaf plot.
Summative Assessment Task
Students create a line plot to record data on how many minutes the students in Mrs. Blake's class read on Tuesday night. Students also determine the total number of hours the entire class read.
Instructional Tasks/Formative Assessments
Students create a line plot to record the amount of food hunting hawks need to eat before bedtime. Students will also draw two mathematical conclusions from the data.
Students create a line plot to correspond with class data that records the height of bean plants the class is growing for Mother's Day. Students will also make conclusions about the data in their line plot.
Given a list of data, students create a line plot to represent the amount of formula newborn puppies drink at their noon feeding. Students will also draw mathematical conclusions about the data.
Students create a line plot to represent class data on the distances traveled by snails. Students then determine how far most snails traveled before they stopped to rest.
