CPM Releases Statistics Supplements –
The statistics and probability lessons from the CPM Core Connections series have been posted here. This series of Core Connections Statistics Supplements replaces the Statistics and Probability Resource that was previously available. These files are available for download free of charge.
Lessons aligned to the statistics and probability content standards of the CCSS
For a class not using Common Core State Standards (CCSS)–aligned curriculum materials, these lessons supplement the statistics and probability content to meet the statistics and probability standards of the CCSS. Even if CCSS-aligned curriculum is being used in the classroom, in the transition period to CCSS, it is possible, even likely, that a class will not cover all of the statistics and probability content standards. This content will have to be taught in a subsequent course. These CPM Statistics Supplements provide the materials for any delayed statistics content.
The CPM Statistics Supplements are complete lessons that include the content, learning strategies, teacher notes and methodologies, resource pages, closure activities, review problems, and Checkpoints.

New curriculum and technical support availableThree CPM mentor teachers are now available to help parents, students and teachers who have questions about the CPM program. This support is primarily for questions about using the program, its technology and the website. To use CPM's support service, go to http://www.cpm.org/support to see the available services. Follow the prompts to get help. Note that this service is not a "homework helpline." That support is at http://www.cpm.org/students/homework.
The CPM mentors are:
Middle grades courses: Susan Hoffmier, Auburn, CA
High school core courses: Melissa Thomley, Madison, WI
Transition to college courses: Sarah Morrison, Glendale, CA
Common Core State Standards (CCSS):CPM now offers a new series of textbooks to meet the grade 6-8 and high school CCSS content and practice standards: Core Connections, Courses 1 - 3 and Core Connections Algebra 1 & 2 and Geometry. Learn how this series as well as the original Connections series of CPM textbooks are fully aligned with the CCSS Content and Mathematical Practice Standards. CPM can also provide professional development centered around embedding the eight CCSS Mathematical Practices into your current lessons and current textbook from any publisher. Start moving on the path to the CCSS today!
Parent e-book licenses are now available!Parents may purchase a one-year e-book license of their student's book for $10 by calling CPM and using a credit card. See order form for a complete list of available one-year licenses. Contact CPM at (209) 745-2055.
Core Connections Algebra 2: 9.2.1: How can an experiment show cause and effect?
9-45. Testing Cause and Effect with Experiments
Consider this question: "Does a new type of motor oil improve gas mileage?" Assuming this new motor oil was already available to the public, you could survey some car owners who use the oil and some who do not and compare their mean gas mileages.
a.) What problems might arise from using this method? What are some possible lurking variables that could affect the outcome of the study? [answer]
b.) After reading the Math Notes box in this lesson, design an experiment to help decide whether the new motor oil improves gas mileage. [answer]
c.) Sometimes a group gets no treatment. If people are involved, they may get a placebo (a treatment with no effect) so the psychological effects of participating in an experiment are the same among the groups. If you have not already done so, include a no-treatment or placebo group in your experiment. [answer]
