Mathematical Standards

5.MD.A
Convert like measurement units within a given measurement system. (5.MD.A.1)

Standards for Mathematical Practice

MP1.
Make sense of problems and persevere in solving them.
MP2.
Reason quantitatively.
MP4.
Model with mathematics.
MP5.
Use appropriate tools strategically.

Students review how to use averages and graphs to answer questions about data. Students pose questions for investigation and define variables for study. They find the median and mode (averages) of data sets and use them to answer questions about the data.

Content in this Lesson

  • Selecting, collecting, and organizing data to answer a question.
  • Naming numerical variables to study [E1].
  • Making a bar graph [E4].
  • Finding the median of a data set [E5].
  • Finding the mode of a data set [E6].
  • Reading a table or bar graph to find information about a data set [E7].
  • Modeling real-world situations with bar graphs [E8].
  • Making predictions and generalizations about a data set using a data table, graph, median, and mode [E9, 10].

Materials Preparation

Arrow on Self-Adhesive Note. Draw a single dark arrow on 3 or 4 adhesive notes. These adhesive notes will be used in Part 2 of the lesson to show the median number in a data set using a list, a graph, and a data table.

Prepare Optional Compare Populations Targeted Practice. Make a list of example investigation questions. Place the list and copies of the Centimeter Grid Paper Master in a center to provide targeted practice.

MPE1.
Know the problem. I read the problem carefully. I know the questions to answer and what information is important.
MPE5.
Show my work. I show or tell how I arrived at my answer so someone else can understand my thinking.
