Personal Objective: This week I chose to look at how to represent and interpret data (picture graph and a bar graph) at the 2nd grade level. My goal was to create a clear visual step by step breakdown on how to analyze/collect information through sorting, the use of tally marks and picture/bar graphs.
Common Core Standard:
2nd Grade: 2.MD
Represent and interpret data
10. Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put-together, take-apart, and compare problems using information presented in a bar graph.

Reflection: What I liked best about taking a closer look at graphing was that the end result is rewarding because the information that has been compiled and sorted stands out so clearly. I think that the use of manipulitives to teach math basics is a fun way to allow students to work through what they are learning hands on. I explored this by mixing up little rubber fruit toys and manually sorting them by type. Once they were sorted I used tally marks to count them. Lastly, I assembled them onto a bar graph and color coded them. Working through this process gave me better insight to how I might go about teaching the subject matter to 2nd grade students.
PICTURE/BAR GRAPHING & TALLYING
Count items using tally marks
Enter data gathered (bar graph)
Crosscheck your work using manipulitives (picture graph)
How to solve a word problem using the information on the graph:
How many more bananas are there than strawberries?
The graph shows there are 6 bananas and 2 strawberries.
6 - 2 = 4
Answer: There are 4 more bananas than strawberries.
