Essential Understandings
Concrete:
- Given a data display, identify outliers in the data set.
- Identify the highest and lowest value in a data set given a number line and matching symbols (concept of range).
- Identify the concept of median using concrete representations of data (create a bar graph with an odd number of bars using snap cubes; arrange from shortest to tallest; students place fingers on two outside towers, knock towers over and move inward until they reach the one middle tower left standing).
- Find the mean using concrete materials.
- Identify the median and the mean of the data set.
- Calculate the mean using a pre-slugged template of data points.
- Order data set.
- Understand the following concepts and vocabulary: median, mean and outliers.
- When comparing the mean and the median, if the mean is larger than the median, the data is skewed to the right. If the mean is smaller than the median the data is skewed to the left. If the mean equals the median, the data is symmetric.

Cluster:
Summarize, represent, and interpret data on a single count or measurement variable. (Algebra 1 - Additional Cluster) (Algebra 2 - Additional 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. |
