Essential Understandings
Concrete:
- Use manipulatives and a ruler to measure the lengths of an object. Record the measurement from several different students. (The measurements will be slightly different.) Determine an acceptable range of measurement that would still be considered correct.
- Understand that the margin of error describes the level of accuracy of an experiment. The margin of error describes a range that helps determine the trustworthiness of results. For example: An election results poll has a +/– 3% margin of error.
- Understand that a smaller margin of error indicates trustworthy results and a larger margin of error means the results are not considered as accurate.

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. |
