In this unit...
Students will understand that...
Organized data allows us to answer questions and to make inferences and predictions based on that data.
Purpose dictates the most appropriate representation of data.
Students will keep considering the following questions:
How n I used my data to answer questions and make predictions?
What is the best way to display my data?
Students will know:
data can be sorted by attributes
frequency tables, dot plots, pictographs, and bar graphs represent categorical or numerical data
a frequency table represents how often an item, a number, or a range of numbers occurs
tallies or counts record frequencies
organizing data makes it easier to see patterns
a pictograph or cell might represent more than one piece of data
Students will be skilled at:
developing a survey question and collecting data
organizing data in multiple categories
creating a frequency table, dot plot, pictograph and bar graph with scaled intervals
interpreting information in a frequency table, dot plot, pictograph, and bar graph with scaled intervals
asking and answering questions using information from frequency tables, dot plots, pictographs, and bar graphs
drawing conclusions and making predictions using information from graphs
writing and solving problems one and two step problems with scaled intervals
applying the mathematical standards
