#### PREKINDERGARTEN STANDARDS

#### Problem Solving Strand

Students will build new mathematical knowledge through problem solving

Explore, examine, and make observations about a social problem or mathematical situation

Interpret information correctly, identify the problem, and generate possible solutions

Students will solve problems that arise in mathematics and in other contexts

Act out or model with manipulatives activities involving mathematical content from literature and/or story telling

Formulate problems and solutions from everyday situations (e.g., as counting the number of children in the class or using the calendar to teach counting)

Students will apply and adapt a variety of appropriate strategies to solve problems

Use informal counting strategies to find solutions

Experience teacher-directed questioning process to understand problems

Compare and discuss ideas for solving a problem with teacher and/or students to justify their thinking

Use manipulatives (e.g., tiles, blocks) to model the action in problems

Use drawings/pictures to model the action in problems

Students will monitor and reflect on the process of mathematical problem solving

Explain to others how a problem was solved, giving strategies

#### Reasoning and Proof Strand

Students will recognize reasoning and proof as fundamental aspects of mathematics

Understand that mathematical statements can be true or false

Students will make and investigate mathematical conjectures

Investigate the use of knowledgeable guessing as a mathematical tool

Explore guesses, using a variety of objects and manipulatives

Students will develop and evaluate mathematical arguments and proofs

Listen to claims other students make

#### Communication Strand

Students will organize and consolidate their mathematical thinking through communication

Understand how to organize their thought processes with teacher guidance

Students will communicate their mathematical thinking coherently and clearly to peers, teachers, and others

Share mathematical ideas through the manipulation of objects, drawings, pictures, and verbal explanations

Students will analyze and evaluate the mathematical thinking and strategies of others

Listen to solutions shared by other students

Formulate mathematically relevant questions with teacher guidance

Students will use the language of mathematics to express mathematical ideas precisely

Use appropriate mathematical terms, vocabulary, and language

#### Connections Strand

Students will recognize and apply mathematics in contexts outside of mathematics

Recognize the presence of mathematics in their daily lives

Use counting strategies to solve problems in their daily lives

Recognize and apply mathematics to objects and pictures

#### Representation Strand

Students will create and use representations to organize, record, and communicate mathematical ideas

Use multiple representations, including verbal language, acting out or modeling a situation, and drawing pictures as representations

Use standard and nonstandard representations

Students will use representations to model and interpret physical, social, and mathematical phenomena

Use objects to show and understand physical phenomena (e.g., guess the number of cookies in a package)

Use objects to show and understand social phenomena (e.g., count and represent sharing cookies between friends)

Use objects to show and understand mathematical phenomena (e.g., draw pictures to show a story problem, show number value using fingers on your hand)

#### Number Sense and Operations Strand

Students will understand numbers, multiple ways of representing numbers, relationships among numbers, and number systems

Count the items in a collection and know the last counting word tells how many items are in the collection (1 to 10)

Count out (produce) a collection of a specified size 1 to 10

Verbally count by 1s to 10

Explore the different representations of a group of objects

Draw pictures or other informal symbols to represent a spoken number up to 5

Draw pictures or other informal symbols to represent how many in a collection up to 5

Recognize numerals (0-5)

Use and understand the terms first and last

Students will understand meanings of operations and procedures, and how they relate to one another

Develop addition and subtraction readiness with sums up to 4 and subtraction involving one to four items, using manipulatives

#### Algebra Strand

Students will recognize, use, and represent algebraically patterns, relations, and functions

Duplicate simple patterns using concrete objects

#### Geometry Strand

Students will use visualization and spatial reasoning to analyze characteristics and properties of geometric shapes

Match shapes, first with same size and orientation, then with different sizes and orientation

Informally play with solids (e.g., building blocks)

#### Measurement Strand

Students will determine what can be measured and how, using appropriate methods and formulas

Develop language such as bigger, longer, and taller to discuss length

Relate specific times such as day and night

#### Statistics and Probability Strand

Students will collect, organize, display, and analyze data

Sort and organize objects by one attribute (e.g., color, size, or shape)

Use physical objects to make graphs

Count and compare groups formed (quantify groups formed)

Describe the attributes of objects
