Core Connections Integrated I- Grade Expectations and Curriculum Guide

What Is Core Connections Integrated I?

Core Connections Integrated I (CC Integrated I) is a 9th-grade mathematics course designed by CPM Educational Program. Unlike traditional algebra, this course weaves together algebra, geometry, probability, and statistics into a unified curriculum.

The idea is simple: math concepts don't exist in isolation, so why teach them that way?

This course typically serves as the first year of a three-year integrated math sequence (Integrated I, II, and III) that prepares students for precalculus and calculus. Some schools use it as an alternative to the traditional Algebra 1 → Geometry → Algebra 2 pathway.

Grade Level Expectations

Here's what you need to know about where CC Integrated I fits academically:

• Designed for 9th graders (ages 14-15)
• Counts as a high school math credit
• Prepares students for CC Integrated II the following year
• Meets most state standards for first-year high school mathematics

If your student is advanced, they might take it in 8th grade. If they're struggling, some schools allow 10th graders to enroll. But the standard expectation is 9th grade.

Core Topics Covered

Chapter-by-Chapter Breakdown

CC Integrated I spans roughly 6 chapters, though this varies by edition. Here's what students actually encounter:

• Chapter 1: Functions — Introduction to function notation, domain, range, and interpreting graphs
• Chapter 2: Linear Functions — Slope, equations of lines, systems of equations
• Chapter 3: Transformations and Solving — Geometric transformations paired with equation solving
• Chapter 4: Modeling Data — Scatter plots, regression, correlation
• Chapter 5: Sequences — Arithmetic and geometric sequences, recursive definitions
• Chapter 6: Congruence and Proofs — Triangle properties, rigid motions, formal proofs

The curriculum emphasizes problem-based lessons where students discover concepts through investigation before receiving direct instruction. This flipped approach frustrates some students who expect traditional lectures.

How CC Integrated I Differs from Traditional Algebra 1

Most parents expect their 9th grader to take Algebra 1. CC Integrated I isn't the same thing. Here's the honest comparison:

The integrated approach works well for students who struggle with abstract numbers but grasp concepts when connected to visual or real-world contexts. It fails students who need clear procedures and step-by-step instruction.

Homework and Assessment Structure

CPM courses have a specific rhythm that catches many families off guard:

• Daily homework — Assigned every class day, typically 20-30 problems
• Team homework — Problems meant to be solved collaboratively
• Chapter tests — Usually 2-3 per semester
• Cumulative finals — Often required by school policy

The homework load is heavy. CPM believes students learn math by doing math, which means tons of practice problems. If your student is spending more than 45 minutes on nightly homework, something is wrong—either they're not using their class time effectively, or they're stuck and need help.

Common Struggles and How to Address Them

Struggle 1: The "I Don't Get It" Problem

CC Integrated I introduces topics through investigation. If students don't engage with the investigation, they miss the foundation. They then can't do the homework.

Fix: Read the investigation problems before class. Previewing the lesson makes in-class time productive instead of confusing.

Struggle 2: No Answer Key Access

Parents can't help because CPM doesn't provide complete solution keys to students. The thinking is that students should verify their own reasoning, not copy answers.

Fix: Use the Checkpoints at the end of each chapter. These are the problems your student should be able to solve to demonstrate mastery. If they can't do the checkpoints, they need extra help before moving forward.

Struggle 3: Group Work Doesn't Work for My Kid

Some students thrive in teams. Others get left behind or become dependent on stronger group members.

Fix: Ask the teacher about accountability structures. At home, have your student explain problems to you out loud—teaching is the best way to identify gaps.

Graphing Calculator Requirements

CC Integrated I requires a graphing calculator. The curriculum assumes students have access to one daily.

Recommended options:

• TI-84 Plus CE — Most common, allowed on most standardized tests
• TI-Nspire CX — More powerful, slightly steeper learning curve
• Desmos — Free online graphing calculator, sufficient for most CC Integrated I needs

Don't skip this. Trying to do the course without a graphing tool handicaps your student. Tests often include calculator-active sections.

Getting Started: A Practical Guide

Before the School Year Starts

• Purchase or borrow a graphing calculator (TI-84 or Desmos)
• Obtain the textbook (Core Connections Integrated I, 3rd edition is current)
• Create a CPM Parent Guide account if your school offers one
• Review the first chapter's investigation problems—don't solve them, just read them

During the School Year

• Check the Checkpoints after each chapter—these are your progress indicators
• Don't let homework pile up; CPM builds on previous concepts constantly
• Form a study group early; the curriculum assumes collaboration
• Use Khan Academy or YouTube as supplementary resources when the textbook isn't clicking

Before Tests

• Redo checkpoint problems without looking at solutions first
• Review team homework questions—these often appear on tests
• Practice with past exams if your teacher provides them

Is CC Integrated I the Right Path?

Not every student thrives in the integrated model. Here's when to consider alternatives:

• Switch to traditional Algebra 1 if your student needs highly structured, procedural instruction
• Consider tutoring immediately if your student fails a chapter test
• Talk to the math department if your student consistently scores below 70%—don't wait until semester grades are final

The integrated sequence prepares students well for higher-level math, but only if they master the content. A weak foundation in CC Integrated I makes CC Integrated II nearly impossible.

The Bottom Line

Core Connections Integrated I is a solid curriculum that works well for self-directed learners and students who enjoy discovering math concepts. It's a poor fit for students who need clear procedures, immediate feedback, and traditional instruction.

Know your student. If they struggled with middle school math, CC Integrated I will likely frustrate them. If they enjoyed math and can work through confusing problems without giving up, they'll probably do fine.

Get the calculator. Do the Checkpoints. Don't let homework slide. That's the entire formula for success in this course.
