Graphing Picture and Bar Graphs
Learning Context
Purpose
Purpose/Rationale for Learning Experience: In our class we use Grade 2 Investigations: in Number, Data, and Space. Part of session 2.5 in unit 1 asks students to identify “How Many Pockets?” The pocket lesson collecting class data, was exciting and engaging. Students asked the next day if pockets could be counted again. We began to keep track of how many pockets students wore for seven days. In order to interpret the data and use it in another manner, I created a lesson about graphing. In second grade, students learn how to draw a picture and bar graph to represent data collected. Students compare data results to figure out which are the most and least represented.
Objectives
Objective #1: Students sort and count objects to graph with 95 – 100% accuracy.
Objective #2: Students create a picture graph of cubes after counting and sorting them with 85 – 100% accuracy.
Objective #3: Students create a bar graph using M&Ms after counting and sorting them with 85 – 100% accuracy.
Supporting Objectives
- Students participate in collaborative conversations as a group. They will follow the rule of “one person speaks at a time.”
- Students describe key information that must be taken from manipulatives or graphics and discuss adding it to the graphs on the “Graphs” PowerPoint presentation.
Enduring Understanding
Enduring Understanding(s):
-A graph is a way of keeping track when we sort and count things (data).
-Graphs let us see quickly how many things we have.
-Graphs help us compare numbers of different things.
-A picture graph uses pictures to represent the data collected and sorted.
-A bar graph uses rectangles to represent data on a numbered plane.
Essential Questions
Essential Question(s):
-What are graphs used for?
Guiding Question(s):
-What is a picture graph?
-What is a bar graph?
-Which is the most?
-Which is the least?
Key Subject-Specific Vocabulary:
-data- the number of items collected and counted
-picture graph- picture representation of data collected and sorted in a table
-bar graph- rectangles colored in a table to represent how many of each data was collected
Overview of What Students Need to Know
Prior to Learning Experience:
-Students have background knowledge on how to count and sort data.
-Students know how to write numbers
-Students can distinguish between most and least in comparison to the whole amount
-Students know how to draw and color
-Students understand class rules and procedures [1, 2].
During and After the implementation of the Learning Experience:
-Students are able to collect data by sorting and counting.
-Students are able to represent data collected using pictures in a graph.
-Students are able to represent data collected by coloring squares to correspond to the number of bars in a graph.
