Data Unit


Unit Summary:

Students add, subtract, multiply and divide rational numbers, and use them to solve problems dealing with data, measurement, and personal finance.


Vocabulary:
Data, Categorical data, Numerical data, Whole number, Fraction, Decimal, Categories
Frequency table, Dot Plot, Stem-and-Leaf Plot, Graph title, Labels,Scaled interval


Essential Questions:
Why is it so important to know how to solve problems involving different measurements?


What concepts are important to understand when solving measurement problems?


TEKS:
  • 4.9 Data analysis. The student applies mathematical process standards to solve problems by collecting, organizing, displaying, and interpreting data. The student is expected to:
  • 4.9A represent data on a frequency table, dot plot, or stem-and-leaf plot marked with whole numbers and fractions; R
  • 4.9B solve one- and two-step problems using data in whole number, decimal, and fraction form in a frequency table, dot plot, or stem-and-leaf plot. S
  • 4.8 Geometry and measurement. The student applies mathematical process standards to select appropriate customary and metric units, strategies, and tools to solve problems involving measurement. The student is expected to:
  • 4.8C solve problems that deal with measurements of length, intervals of time, liquid volumes, mass, and money using addition, subtraction, multiplication, or division as appropriate.

This unit is all about organizing data.
Here's a great website for this topic. You can even make your own graph here.


Here's a good site for stem and leaf plots.


Here's one for dot plots!
