kx) and inverse (y = k/x).

Data Analysis and Probability
Students will demonstrate understanding of data analysis by posing questions, collecting
data, analyzing the data using measures of central tendency and variation,
and using the data to answer the questions posed. Students will understand the
role of probability in sampling.
M7D1 Students will pose questions, collect data, represent and analyze the data,
and interpret results.
a. Formulate questions and collect data from a census of at least 30 objects and
from samples of varying sizes.
b. Construct frequency distributions.
c. Analyze data using measures of central tendency (mean, median, and mode),
including recognition of outliers.
d. Analyze data with respect to measures of variation (range, quartiles, interquartile
e. Compare measures of central tendency and variation from samples to those
from a census. Observe that sample statistics are more likely to approximate
the population parameters as sample size increases.
f. Analyze data using appropriate graphs, including pictographs, histograms, bar
graphs, line graphs, circle graphs , and line plots introduced earlier, and using
box-and-whisker plots and scatter plots.
g. Analyze and draw conclusions about data, including a description of the relationship
between two variables.

Reading Across the Curriculum
Reading Standard Comment
After the elementary years, students are seriously engaged in reading for learning.
This process sweeps across all disciplinary domains, extending even to the area of
personal learning. Students encounter a variety of informational as well as fictional
texts, and they experience text in all genres and modes of discourse. In the study
of various disciplines of learning (language arts, mathematics, science, social studies),
students must learn through reading the communities of discourse of each of those
disciplines. Each subject has its own specific vocabulary; and for students to excel
in all subjects, they must learn the specific vocabulary of those subject areas in context.
Beginning in the middle grades, students start to self-select reading materials
based on personal interests established through classroom learning. Students
become curious about science, mathematics, history, and literature as they form
contexts for those subjects related to their personal and classroom experiences. As
students explore academic areas through reading, they develop favorite subjects
and become confident in their verbal discourse about those subjects.
Reading across curriculum content develops both academic and personal interests
in students. As students read, they develop both content and contextual vocabulary.
They also build good habits for reading, researching, and learning. The Reading
Across the Curriculum standard focuses on the academic and personal skills students
acquire as they read in all areas of learning.
M7RC1 Students will enhance reading in all curriculum areas by:
a. Reading in All Curriculum Areas
• Read a minimum of 25 grade-level appropriate books per year from a variety
of subject disciplines and participate in discussions related to curricular
learning in all areas.
• Read both informational and fictional texts in a variety of genres and modes
of discourse.
• Read technical texts related to various subject areas.
b. Discussing books.
• Discuss messages and themes from books in all subject areas.
• Respond to a variety of texts in multiple modes of discourse.
• Relate messages and themes from one subject area to messages and themes in
another area.
• Evaluate the merit of texts in every subject discipline.
• Examine author’s purpose in writing.
• Recognize the features of disciplinary texts.
c. Building vocabulary knowledge
• Demonstrate an understanding of contextual vocabulary in various subjects.
• Use content vocabulary in writing and speaking.
• Explore understanding of new words found in subject area texts.
d. Establishing context
• Explore life experiences related to subject area content.
• Discuss in both writing and speaking how certain words are subject area related.
• Determine strategies for finding content and contextual meaning for
unknown words.
