### 1 Counting and Cardinality

- 1.1 Counts Out Loud
- 1.1.a Shows interest in and awareness of counting.
- 1.1.b Rote counts zero to ten and beyond with increasing accuracy.

- 1.2 Knows Number Names and Symbols
- 1.2.a Uses numerals and number symbols in the context of daily routines, activities, and play.
- 1.2.b Uses and creates symbols to represent numbers.
- 1.2.c Uses a variety of materials (i.e. clay, sand, shaving cream) to write and form numerals and numeral-like symbols.
- 1.2.d Identifies numerals zero to ten.
- 1.2.e Differentiates some written numerals from written letters.

- 1.3 Compare Numbers and Quantities
- 1.3.a Compares two sets of objects using terms such as greater than, less than, or equal to.

- 1.4 Counts to Tell Number of Objects
- 1.4.a Identifies quantities of three to five objects without counting using visual approximation (subitize).
- 1.4.b Demonstrates the ability to match object to object in a group (One-to-one correspondence).
- 1.4.c Counts groups of objects using a number word for each object (Rational Counting).

- 2.1.a Recognizes that adding increases the number of objects in a group.
- 2.1.b Describes changes in two or more sets of objects when they are combined.
- 2.1.c Recognizes that taking away (subtracting) decreases the number of objects in a group.
- 2.1.d Describes changes in a set of objects when they are separated into parts.
- 2.1.e Counts on from the larger number for addition.

- 2.2 Patterning

- 2.2.f Describes similarities and differences in patterns.

### 3 Measurement and Data

- 3.1 Sorts and Classifies
- 3.1.a Sorts and classifies objects by one or more attributes (e.g., size, color, shape, texture, use).
- 3.1.b Explains how items were sorted into groups.

- 3.2 Data Analysis
- 3.2.a Ask questions to gather measurable data.
- 3.2.b Displays data to answer simple questions about themselves or the environment.
- 3.2.c Uses descriptive language to compare data in picture graphs or other concrete representations.
- 3.2.d Analyzes data from charts and graphs to answer questions.

- 3.3 Measures
- 3.3.a Compares objects and uses terms such as longer-shorter, hotter-colder, and faster-slower.
- 3.3.b Uses non-standard units of measurement (e.g., hands, bodies, containers) to estimate measurable attributes.
- 3.3.c Uses various standard measuring tools for simple measuring tasks.
- 3.3.d Orders objects by measurable attributes.
- 3.3.e Uses appropriate vocabulary to describe time and sequence related to daily routines.

### 4 Geometry

- 4.1.e Compares, describes, analyzes, and sorts two- and three- dimensional objects in the environment using formal and informal mathematical language with prompting and support based on their attributes.

- 4.2 Spatial Reasoning
- 4.2.a Uses and responds to spatial language (e.g., between, inside, under, above, behind).
- 4.2.b Describes the relative position or location of objects in relation to self or to other objects with mathematical precision.
