# Grade Two

**Grade Two Mathematics Program**

Your child will be using Pearson EnVision Math this year. The resources fully support the Massachusetts Mathematics Curriculum Frameworks.

Pearson has a website, www.pearsonsuccessnet.com, which can be accessed for additional information about these materials. Each student will receive a username and password and will have full access to their grade level math book and all program materials online. Teachers are able to assign homework and review sheets through this website. For technological assistance, you can reach the Pearson Tech Help Line at 1-800-234-5832 or contact them through the website above.

EnVision Math is a math program that balances skill instruction with instruction that develops conceptual understanding through problem-based interactive and visual learning. This research-based program is aligned with Massachusetts Mathematics Curriculum Frameworks.

The program’s philosophy has 3 key focal points:

- Conceptual Development- Interactive Learning + Visual Learning
- Ongoing Assessment, Diagnosis, and Intervention
- Differentiated Instruction

Topics are organized around math strands focusing on the Big Ideas and Essential Understandings of math. The Big Ideas are the conceptual underpinnings of the program and the glue that provides conceptual cohesion across lessons, topics, grades, and standards. Big Ideas connect Essential Understandings which occur within and across lessons.

The Massachusetts Math Curriculum Frameworks are divided into content and practice standards. The content standards outline the math concepts students should know by the end of the year. The practice standards are the mathematical habits of mind that students will develop as they go through the grades.

**Units of Study**

The following is a list of topics which provide a quick synopsis of concepts to be explored this year. As you begin to see your student’s work as it arrives home, and as it is shared when you visit the classroom, you will have a better understanding of the depth and quality of the concepts your child will be learning.
