PK.1.1 The child counts out loud and uses number words in daily conversations.
PK. To build an understanding of counting, children need environments that are rich in mathematical language and provide varied opportunities to count in ways that are personally meaningful, challenging, and fun.
PK.1.1.a Shows interest in and awareness of counting.
PK.1.2 The child identifies numerals and uses number words in daily activities.
PK. To build an understanding of number names and symbols children need number rich environments that allow them to explore and play with numbers and numerals throughout the day and across the curriculum.
PK.1.2.a Uses numerals and number symbols in the context of daily routines, activities, and play.
PK.1.2.b Uses and creates symbols to represent numbers.
PK.1.3 The child uses number words and counting to identify quantity.
PK. Learning the meaning of numbers begins with hands-on experiences using a variety of objects found in the home, the classroom and nature. To build an understanding of "how much" and to explore number relationships, children need daily experiences involving counting in ways that are personally meaningful, challenging, and fun.
PK.1.3.a Counts groups of objects using one-to-one correspondence (one object for each number word).
PK.1.4 The child applies a range of strategies such as counting or matching to compare sets of objects.
PK. Learning the meaning of numbers begins with hands-on experiences, using a variety of objects found in the home, the classroom and nature. To build an understanding of numbers and the quantities they represent, children need daily experiences involving comparing groups of objects in ways that are personally meaningful, challenging, and fun.
PK.1.4.a Compares two sets of objects using terms such as more, fewer, or the same.
PK.2.1 The child combines and separates groups of objects and names how many.
PK. Learning the meaning of a number begins with hands-on experiences using a variety of objects found in the home, the classroom, and nature. To build an understanding of numbers and to discover number relationships, children need opportunities to describe the changes that result from putting sets of objects (e.g., blocks, animals, toy people) together or taking them apart.
PK.2.1.a Demonstrates an understanding that adding increases the number of objects in a group.
PK.2.1.b Describes changes in two or more sets of objects when they are combined.
PK.2.2 The child recognizes, copies, extends, describes and creates patterns.
PK. Recognition and investigation of patterns are important components of a child's development. A child's ability to work with patterns is the precursor to mathematical thinking, especially algebraic processes. Children need frequent opportunities to engage in pattern-related activities such as playing with repetitive sounds and movement or noticing patterns in textures and pictures.
PK.2.2.e Describes similarities and differences in patterns.
PK.3 Measurement and Data
PK.3.1 The child sorts and groups objects by a variety of characteristics/attributes.
PK. Recognizing relationships between objects allows young children to make generalizations and predictions beyond information directly available to them. The ability to think logically and to reason (problem solve) extends far beyond mathematical boundaries.
PK.3.1.a Sorts and classifies objects by one or more attributes (e.g., size, color, shape, texture, use).
PK.3.1.b Explains how items were sorted into groups.
PK.3.2 The child collects, organizes, displays, and describes relevant data.
PK. Children are natural observers and questioners. To build upon this strength, adults should facilitate children's opportunities to ask questions, sort and classify objects, collect and display information, and talk about what is meaningful to them.
PK.3.2.a Asks questions to gather information.
PK.3.2.b Displays data to answer simple questions about themselves or the environment.
PK.3.3 The child uses measurement to describe and compare objects in the environment.
PK. Starting at a very young age, children compare who is taller or who has more. Immersing children in measurement activities provides them with opportunities to explore, compare, and discuss the use of measurement in their environment.
PK.3.3.a Compares objects and uses terms such as longer-shorter, hotter-colder, and faster-slower.
PK.4.1 The child uses and demonstrates an understanding of positional terms.
PK. Geometry for young children involves observing, playing with, and purposefully investigating shapes that are found in their environment. Children spontaneously make spatial comparisons. This familiarity is a foundation for more complex learning experiences involving shape, position, and orientation in space.
PK.4.1.a Uses and responds to positional terms (e.g., between, inside, under, above, behind).
PK.4.2 The child recognizes names and describes common shapes and their properties.
PK. Geometry for young children involves observing, playing with, and purposefully investigating shapes that are found in their environment. Beginning in infancy, children compare objects by form and shape. This familiarity is a foundation for more complex learning experiences involving shape, position, and orientation in space.
