Graphing Picture and Bar Graphs

Assessment Plan

Participation and Accuracy: A Participation and Accuracy checklist is used to record student activity during lessons and the points transfer to an overall participation grade.
Students receive a check plus if their answer was correct and a check if they participated but their answer was incorrect.

Diagnostic: This lesson did not have an initial diagnostic tool because it was spontaneous. In the future the lesson will have two pre-assessment work sheets. A Farm Animal Picture Graph and a Bar Graph of Pets from www.superteacherworksheets.com.

Formative:After the PowerPoint presentations, students work on the Cubes Picture Graph and M&Ms Bar Graph sheets [1, 2], students work on these two sheets independently first using cube manipulatives for the picture graph and then M&Ms “fun size” bags for the bar graph.

Summative: After the learning experience, students complete the Picking Pumpkin Foods Scholastic News: Reading a Bar Graph sheet [1]. The sheet surveys a class’s favorite pumpkin food. Words and pictures are used to represent the data collected and organized into a bar graph. The students must bubble in the amount of food represented by each picture in the question relating to the bar graph data. Students must also determine which food more children select and calculate the total amount of two foods together. This assessment is used to see if students understand how to read a bar graph and also to understand if students understand picture representations.

Future lessons will use two sheets similar to the formative assessment sheets. Button Picture Graph and Skittles Bar Graph sheets [1, 2] are comparative summative assessments that congruently and validly compare to the formative assessment. Both graphs will use buttons and the Graph Rubric will be used to assess the student work.

Category	4	3	2	1
Picture Graph Accuracy Weight: 1pt Score:___/4	-All the color categories are identified and the word is written out. -A cube/square is drawn as a link or individually to represent the number of cubes for each color. -The number of cubes illustrated is correctly quantified. -The colors of the most and least cubes are identified.	- Three out of four of the color categories are identified and the word is written out. -A cube/square is drawn as a link or individually to represent the number of cubes for each color. -One of the numbers of cubes illustrated does not match the quantified number. -The color of the most or least cubes is identified.	-Two out of the four of the color categories are identified but the word is not written out. -The bar is colored-in and segmented but does not resemble cube in the pictures. -Two or Three of the number of cubes illustrated do not match the quantified numbers. -The color of the most or least cubes is identified.	-The color category is not identified. -The bar is colored in but there is no representation of a cube picture. -The number of cubes illustrated is not quantified. -The colors of the most and least cubes are not identified.
Bar Graph Accuracy Weight: 1pt Score:___/4	-The boxes representing the number of M&Ms are colored representing the amount found in the bag. -The number of boxes colored is correctly quantified. -The colors of the most and least M&Ms are identified.	-The boxes representing the number of M&Ms are colored representing the amount found in the bag but one or two may be crossed out. -The number of boxes colored is correctly quantified. -The colors of the most or least M&Ms are identified.	-The boxes representing the number of M&Ms are colored representing the amount found in the bag but tree or four may be crossed out. -The number of boxes colored does not equal the number quantified. -The colors of the most or least M&Ms are identified.	-The boxes representing the number of M&Ms are not colored representing the amount found in the bag. -The number of boxes colored does not equal the number quantified. -The colors of the most or least M&Ms are not identified.
