This 7th grade Math parent guide explains the content in straightforward terms so they can support their children’s learning at home and will encourage caretaker engagement with lessons.

Our Teacher Guides are meant to support the use of our online course and unit content. Please use these to accompany the use of our content and for ideas to support struggling learners, those needing extension and for additional resources.

Students learn about sampling bias by working in three separate groups to survey students, parents, and teachers about the amount of homework students ought to have. They report and compare the responses from each of the three groups to see how the results differ. Activity sheets, discussion questions, ideas for assessment and extensions, and Internet links are included.

The story of "The Beauty and the Beast" has captivated us for many years.  It is fun to read or watch a video of.  But did it really happen?  It is fun to compare fiction and nonfiction.  Most students will in their backgrounds relate to a story like this.  Also it is fun for students to learn and then survey others based on what they have learned.

The purpose of this lesson is for students to make a hypothesis, and then doing an experiment to test each students hypothesis. Students will collect and record their data, use graphical methods to describe their data, and finally analyze and interpret their results in the context of the activity.

This task introduces the fundamental statistical ideas of using data summaries (statistics) from random samples to draw inferences (reasoned conclusions) about population characteristics (parameters). In the task built around an election poll scenario, the population is the entire seventh grade class, the unknown characteristic (parameter) of interest is the proportion of the class members voting for a specific candidate, and the sample summary (statistic) is the observed proportion of voters favoring the candidate in a random sample of class members.

This lesson unit is intended to help you assess how well students are able to: solve simple problems involving ratio and direct proportion; choose an appropriate sampling method; and collect discrete data and record them using a frequency table.

In this lesson, students use data from a random sample to estimate a population proportion.

The task is designed to show that random samples produce distributions of sample means that center at the population mean, and that the variation in the sample means will decrease noticeably as the sample size increases. Random sampling (like mixing names in a hat and drawing out a sample) is not a new idea to most students, although the terminology is likely to be new.

Students learn how to gather information about a large population based on a representative sample whose makeup is similar.

This resource allows students to write an appropriate survey question, describe a reasonable way to select a random sample of students, create a table or graph appropriate for the categorical data collected, and use data summarized in the table or graph to draw a conclusion.

In this lesson, students understand the term sampling variability in the context of estimating a population proportion. Students know that increasing the sample size decreases sampling variability.

In this lesson, students select a random sample from a population. Given a description of a population, students design a plan for selecting a random sample from that population.

This investigation focuses on guiding students as they collect and interpret data from a spinner experiment with outcomes that are equally likely. Students will have the opportunity to organize the collected data in tables and graphs and will draw conclusions and make predictions based on the data collected.

In this unit on gathering statistical data, students find and use measures of center to distinguish between two different data sets.
