Mathematics Curriculum Supplement
Grade 7 (7.SP.A.1)
Grade: 7
Mathematics
Supporting Standard2
7.SP.A.1 Understand that statistics can be used to gain information about a population by examining a sample of the
population; generalizations about a population from a sample are valid only if the sample is representative of that
population. Understand that random sampling tends to produce representative samples and support valid inferences.
Student Learning Targets:
Students will be able to:





define statistics terms such as population, sample, sample size, random sampling, generalizations, valid, biased
and unbiased.
recognize sampling techniques such as convenience, random, systematic, and voluntary.
explain that generalizations about a population from a sample are valid only if the sample is representative of
that population.
apply statistics to gain information about a population from a sample of the population,
generalize that random sampling tends to produce representative samples and support valid inferences.

Highly-Leveraged Standards are the most essential for students to learn because they have endurance, leverage and essentiality.
This definition for highly-leveraged standards was adapted from the website of Millis Public Schools, K-12, in Massachusetts, USA.
http://www.millis.k12.ma.us/services/curriculum_assessment/brochures
Specifically for mathematics, the Highly-Leveraged Standards are the Major Content/Clusters as defined by the AZCCRS Grade
Level Focus documents. They should encompass a range of at least 65%-75% for Major Content/Clusters and a range of 25%-35%
for Supporting Cluster Instruction. See the Grade Level Focus documents at: http://www.azed.gov/azccrs/files/2015/01/k-8-majorand-supporting-content-emphasis.pdf

Supporting Standards are related standards that support the highly leverage standards in and across grade levels.
