The Common Core State Standards for Mathematics

- Pre-Kindergarten Grade 3

Common Core Development

- Initially 48 states and three territories signed

on - As of December 1, 2011, 45 states have officially

adopted - Final Standards released June 2, 2010, can be

downloaded at www.corestandards.org - Adoption required for Race to the Top funds

Preschool

- There are no PreK CCSSM standards

Kindergarten

- The Standards do not dictate curriculum or

teaching methods. Teachers have the autonomy to

use each Standard as they see fit. - Expectations that begin with the word

understand are good opportunities to connect

the practice to the content. - Two critical areas of focus
- Representing, relating, and operating on whole

numbers with sets of numbers - Describing shapes and space

Kindergarten

- Representing, Relating, and Operating on Whole

Numbers - Counting and cardinality
- Know numbers names and the count sequence
- Count to tell the number of objects
- Compare numbers
- Operations and Algebraic Thinking
- Understand addition and subtraction
- Putting together and adding to
- Taking apart and taking from
- Fact families up to 10

Kindergarten

- Place Value 11-19
- 15 ten ones and five ones
- Measurable attributes
- Length and weight
- Classify objects

Kindergarten

- Geometry
- Identify and describe shapes
- 2D and 3D shapes

Kindergarten Whats Different
