• Georgia Standards of Excellence Mathematics
GeorgiaStandards.Org (GSO) is a free, public website providing information and resources necessary to help meet the educational needs of students. The goal of this web site is to provide information that will enhance and support teaching and learning of Georgia standards.
• Kindergarten Mathematics (Engage NY)
In order to assist educators with the implementation of the Common Core, the New York State Education Department provides curricular modules in Pre-K-Grade 12 English Language Arts and Mathematics that schools and districts can adopt or adapt for local purposes.
• Kindergarten Unit 5: Investigating Addition and Subtraction (Georgia Standards)
For numbers 0 10, Kindergarten students choose, combine, and apply strategies for answering quantitative questions. This includes quickly recognizing the cardinalities of less sets of objects, counting and producing sets of given sizes, counting the number of objects in combined sets, or counting the number of objects that remain in a set after some are taken away. Objects, pictures, actions, and explanations are used to solve problems and represent thinking.
• Kindergarten Unit 6: Further Investigation of Addition and Subtraction (Georgia Standards)
For numbers 0 10, Kindergarten students choose, combine, and apply strategies for answering quantitative questions. This includes quickly recognizing the cardinalities of less sets of objects, counting and producing sets of given sizes, counting the number of objects in combined sets, or counting the number of objects that remain in a set after some are taken away. Objects, pictures, actions, and explanations are used to solve problems and represent thinking.
• Many Ways to Do Addition 1
This lesson should be taught after students have had many experiences solving addition equations. The purpose of this task is not to teach or model the addition strategies. Rather the purpose of this task is make explicit different ways students can solve problems so that they will be able to find the most efficient strategy in any given situation and increase their addition fluency.
• My Book of Five
The purpose of this task is to help students develop fluency with addition facts to 5.
• Operations and Algebraic Thinking (K.OA) - Kindergarten Core Guide
The Utah State Board of Education (USBE) and educators around the state of Utah developed these guides for Kindergarten Mathematics - Operations and Algebraic Thinking (K.OA)
