Second Grade

Dear 2nd Grade Families,
We would like to provide you with additional support and resources to help your child at
home with math during 3rd quarter. As you know, we have transitioned to the Common
Core Math Standards. We hope this letter is helpful in supporting your child in math at
home. Please don’t hesitate to contact your child’s teacher with questions.
What are the “Common Core Standards?”
They are standards designed to create clear, consistent expectations for what all students
should learn at each grade level to prepare them for college and career. These standards
help ensure that all students are receiving a high quality education consistently, from school
to school and state to state. These MATH standards stress conceptual understanding. This
‘new’ way of teaching and learning builds a strong foundation for our students.
*Google/YouTube – search the standard number (ex. 2.NBT.1) in Google or YouTube to locate
videos, examples, worksheets, etc.
*Help your child memorize basic facts (addition and subtraction)0
*Discuss/explain and “do” real life math
*Talk with your child and their teacher about his/her performance in math at school
