Students will understand that…
U1 Data are numbers with a context.
U2 Organized data allows us to answer questions and to make inferences and predictions based on that data.
U3 Purpose dictates the most appropriate representation of data.
Students will know …
K1 frequency tables and dot plots represent categorical or numerical data.
K2 stem-and-leaf plots represent numerical data.
K3 organizing data makes it easier to see patterns.
K4 graphs explain real-world situations.
K5 how to select the most appropriate representation of data based on purpose and need.

TEKS
5.1 (A-G) The student uses mathematical processes to acquire and demonstrate mathematical understanding.
5.9 The student applies mathematical process standards to solve problems by collecting, organizing, displaying, and interpreting data.
(A) represent categorical data with bar graphs or frequency tables and numerical data, including data sets of measurements in fractions or decimals, with dot plots or stem-and-leaf plots
(B) represent discrete paired data on a scatter plot
(C) solve one- and two-step problems using data from a frequency table, dot plot, bar graph, stem-and-leaf plot, or scatterplot
