K.1 Numeric Reasoning: Students will develop Numeric Reasoning and an understanding of Number and Operations by solving problems in which there is a need to represent and model real numbers verbally, physically, and symbolically; to explain the relationship between numbers; to determine the relative magnitude of real numbers; to use operations with understanding; and to select appropriate methods of calculations from among mental math, paper-and-pencil, calculators, or computers.

K.1.1 Number sense
K.1.1.1 Count sets of objects up to 20
K.1.1.2 Connect number words and numerals (up to 10) to the quantities they represent using various physical models and representations
K.1.1.3 Sequence numbers and explain what comes before, after and between other numbers
K.1.1.4 Show more than one way to make numbers up to 10.
- Addition: Ways to make a number - addition sentences (First grade - B.6)
K.1.2 Operations
K.1.2.1 Use manipulatives to model putting together and taking apart (e.g., you have one cookie and you get two more cookies
K.1.2.2 Use manipulatives to show more than one way to make a target number up to 6
- Adding: Addition with pictures - sums up to 5 (Kindergarten - I.1)

K.2 Algebraic Reasoning: Students will develop Algebraic Reasoning and an understanding of Patterns and Functions by solving problems in which there is a need to recognize and extend a variety of patterns; to progress from the concrete to the abstract using physical models, equations, and graphs; to describe, represent, and analyze relationships among variable quantities; and to analyze, represent, model, and describe real-world functional relationships.

K.2.1 Patterns and change
K.2.1.1 Sort objects by a given attribute (e.g., size, color, shape)
K.2.1.2 Repeat and extend a simple repeating pattern given the core
- Patterns: Complete missing parts of patterns (Kindergarten - H.2)
K.2.1.3 Find visual patterns in the world around us (e.g., patterns in the rug, in the wallpaper)
K.2.1.4 Discuss things that repeat in cyclic patterns, (e.g., day and night, days of week)
K.2.2 Representations
K.2.2.1 Model join and separate situations with objects and pictures
- Adding: Addition with pictures - sums up to 5 (Kindergarten - I.1)
- Subtracting: Subtract with pictures - numbers up to 5 (Kindergarten - J.1)
K.2.3 Symbols
K.2.3.1 Record mathematical thinking symbolically with teacher assistance
- Sorting, ordering, and classifying: Venn diagrams (Kindergarten - N.5)
- Vocabulary: Sum and difference (Kindergarten - T.1)

K.3 Geometric Reasoning: Students will develop Geometric Reasoning and an understanding of Geometry and Measurement by solving problems in which there is a need to recognize, construct, transform, analyze properties of, and discover relationships among geometric figures; and to measure to a required degree pf accuracy by selecting appropriate tools and units.

K.3.1 Classification
K.3.1.1 Name and sort figures by shape (e.g., rectangle, triangle, circle)
K.3.1.2 Recognize attributes and parts of two-dimensional and three-dimensional shapes
K.3.1.3 Recognize geometric shapes and structures in the environment
- Geometry: Geometry of everyday objects (Kindergarten - S.7)
K.3.2 Location and transformation
K.3.2.1 Find and name locations with simple relationships (e.g., near to, over, under, beside, between, outside, inside)
K.3.3 Measurement
K.3.3.1 Compare the length of two objects by placing them side by side
K.3.3.2 Find items that are longer than or shorter than a given measure (e.g., longer than 10 linker cubes)
K.3.3.3 Talk about time using calendar (e.g., today, tomorrow and yesterday, and the date)
- Time: Read a calendar (First grade - R.11)
K.3.3.4 Describe and compare volume/capacity of two objects (e.g., full/empty, more/less)
- Measurement: Holds more or less (Kindergarten - Q.4)
K.3.3.5 Describe and compare the mass/weight of two objects (e.g., light/heavy)
- Measurement: Light and heavy (Kindergarten - Q.3)

K.4 Quantitative Reasoning: Students will develop Quantitative Reasoning and an understanding of Data Analysis and Probability by solving problems in which there is a need to collect, appropriately represent, and interpret data; to make inferences or predictions and to present convincing arguments; and to model mathematical situations to determine the probability.

K.4.1 Collect
K.4.1.1 Gather and report data about oneself and familiar surroundings using teacher defined categories (preference out of two choices)
K.4.2 Represent
K.4.2.1 Use physical objects to organize and informally represent categorical data
- Data and graphs: Making graphs (Kindergarten - O.1)
K.4.3 Analyze
K.4.3.1 Interpret data by making simple comparisons (e.g., more, less, the same)
K.4.4 Probability
K.4.4.1 Explore events as likely or unlikely based on shared or personal experiences
- Probability: More or less likely (Kindergarten - P.1)
