Essential Understandings
Concrete:
- Use manipulatives to add the numbers in a given data set.
- Use manipulatives to divide the sum of a data set.
- Identify the mean of a data set from manipulatives or pictorial representations.
- Identify the lowest to highest value in a data set given a number line and matching symbols.
- Arrange data from lowest to highest.
- Identify the representation (plastic snap cubes, wiki sticks) of the mode.
- Use concrete materials to produce the mean (leveled plastic snap cubes).
- Find the object or manipulative in a sequence that represents the middle.
- Understand that the measures of center include the mean (average), median (middle value), and mode (most common value).
- Understand that the measures of variability include the range (difference between the largest and smallest value) and standard deviation. (The standard deviation is a statistic that tells you how tightly all the various examples are clustered around the mean in a set of data.)
- Given a measure of center or variability from two populations, make a generalization for the population based on the data.

Cluster:
Make inferences and justify conclusions from sample surveys, experiments, and observational studies. (Algebra 2 - Major 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. |
