Make sense of problems and persevere in solving them.
MP2.
Reason quantitatively.
MP3.
Construct viable arguments and critique the reasoning of others.
MP4.
Model with mathematics.
MP6.
Attend to precision.

Students build ideas about volume and compare relative sizes of units by measuring containers with beans. Students group and count beans by tens and ones and then pool their data to graph the middle, or median, number of beans to compare the quantities.

Content in this Lesson

  • Grouping and counting objects by tens and ones and naming the number of objects [E2].
  • Representing and identifying numbers to 100 [E1].
  • Exploring volume measurement (capacity) [E5].
  • Collecting and organizing information in a data table [E6].
  • Making bar graphs [E7].
  • Exploring the inverse relationship between the unit's size and the number of units needed to measure a container's volume [E4].
  • Comparing quantities [E3].
  • Finding the median of a data set.
  • Using data to solve problems involving volume [E8].
  • Checking the reasonableness of measurements by comparing data [MPE3].
  • Communicating mathematics verbally and in writing [MPE5].

Materials Preparation

Organize Beans. Gather a 2-pound bag of a small bean (e.g., kidney) and a 2-pound bag of a large bean (e.g., lima). Empty both bags into separate large containers and place them in a central location.

Prepare Ten Frames or Egg Cartons. Student pairs can use the Ten Frames Master to arrange their beans into groups of tens and ones. As an alternative, modify one egg carton for each group. Cut and staple them as shown in Figure 1 so they have ten sections instead of twelve. Instead of simply cutting off the end, cut each carton in the middle and staple the two parts so they overlap to create an enclosed container that won't leak beans. Nest cup 5 into cup 4.

E3. 
Compare quantities and represent that relationship using less than, greater than, between (e.g., intervals), and closer to.
E4. 
Recognize that the measure of a volume is dependent on the size of the unit of measure (e.g., a cup is 40 large beans or 80 small beans).
E8. 
Read a table or bar graph to make predictions and solve problems about a data set.
