Mathematics Kindergarten

Strand: OPERATIONS AND ALGEBRAIC THINKING (K.OA)

Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from (Standards K.OA.1-5).

Standard K.OA.2

Solve addition and subtraction word problems within 10. Use objects or drawings to represent the problem.

This task supports students in correctly writing numbers. Because students have to trace the number instead of coloring in a bubble with the number in it or circling the correct number, they gain handwriting practice as well as counting and addition practice.
• 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.
• IXL Game: Subtraction with Pictures - Numbers up to 10
This IXL game helps the kindergartener understand subtraction. This is just one of many online games that supports the Utah Math core. Note: The IXL site requires subscription for unlimited use.
• 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 Mathematics Module 4: Number Pairs, Addition and Subtraction to 10
Module 4 marks the next exciting step in math for kindergartners, addition and subtraction! They begin to harness their practiced counting abilities, knowledge of the value of numbers, and work with embedded numbers to reason about and solve addition and subtraction expressions and equations. In Topics A and B, decomposition and composition are taught simultaneously using the number bond model so that students begin to understand the relationship between parts and wholes before moving into formal work with addition and subtraction in the rest of the module.
• 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.
• 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)
• Ten Flashing Fireflies
The purpose of this task is to help students develop fluency with addition facts to 10.
• What's Missing?
For this task the teacher shows the student 6 counters (small, flat objects). The student is then asked to close his/her eyes. while some of the counters are hidden under a sheet of heavy paper. When the student opens his/her eyes, s/he determines how many were hidden based on the number of counters still showing.
