Essential Understandings
Concrete:
- Identify the categories for a picture graph or bar graph where the data points are represented with concrete objects (Ex: red candy and blue candy).
- Count the concrete objects within each category (Ex: 5 red candy versus 3 blue candy).
- Represent the number of objects counted for each category on the picture graph or bar graph next to the appropriate category (Ex: beside the label ‘red candy’ place the red candy onto the picture graph or bar graph. Beside the label ‘blue candy’ place the blue candy onto the picture graph or bar graph).
- Given a visual representation of data points, identify the categories for a picture graph or bar graph (Ex: red candy and blue candy).
- Count the data points within each category (Ex: 5 red candy versus 3 blue candy).
- For a picture graph, indicate with a symbol the number of objects counted for each category on the picture graph next to the appropriate category (Ex: beside the label ‘red candy’ draw a picture of 5 candies, beside the label ‘blue candy’ draw a picture of 3 candies).
- For a bar graph, draw bars to indicate the number of objects counted for each category on the bar graph above the appropriate category (Ex: above the label ‘red candy’ draw a bar that represents 5 candies, above the label ‘blue candy’ draw a bar that represents 3 candies).
- Understand the following concepts of picture graph, bar graph, value and category.

Represent and interpret data. (Supporting Cluster) : Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters. |
