#### 1.A.1

Identify patterns found in realworld and mathematical situations.

#### 1.A.1.1

Identify, create, complete, and extend repeating, growing, and shrinking patterns with quantity, numbers, or shapes in a variety of real-world and mathematical contexts.

#### 1.D.1

Collect, organize, and interpret categorical and numerical data.

#### 1.D.1.1

Collect, sort, and organize data in up to three categories using representations (e.g., tally marks, tables, Venn diagrams).

#### 1.D.1.2

Use data to create picture and bar-type graphs to demonstrate one-to-one correspondence.

#### 1.D.1.3

Draw conclusions from picture and bar-type graphs.

#### 1.GM.1

Recognize, compose, and decompose two- and three-dimensional shapes.

#### 1.GM.1.1

Identify trapezoids and hexagons by pointing to the shape when given the name.

#### 1.GM.1.2

Compose and decompose larger shapes using smaller two-dimensional shapes.

#### 1.GM.1.3

Compose structures with three-dimensional shapes.

#### 1.GM.1.4

Recognize three-dimensional shapes such as cubes, cones, cylinders, and spheres.

#### 1.GM.2

Select and use nonstandard and standard units to describe length and volume/capacity.

#### 1.GM.2.1

Use nonstandard and standard measuring tools to measure the length of objects to reinforce the continuous nature of linear measurement.

#### 1.GM.2.2

Illustrate that the length of an object is the number of same-size units of length that, when laid end-to-end with no gaps or overlaps, reach from one end of the object to the other.

#### 1.GM.2.3

Measure the same object/distance with units of two different lengths and describe how and why the measurements differ.

#### 1.GM.2.4

Describe a length to the nearest whole unit using a number and a unit.

#### 1.GM.2.5

Use standard and nonstandard tools to identify volume/capacity. Compare and sort containers that hold more, less, or the same amount. 1.GM.3 Tell time to the half and full hour.

#### 1.GM.3.1

Tell time to the hour and half-hour (analog and digital).

#### 1.N.1

Count, compare, and represent whole numbers up to 100, with an emphasis on groups of tens and ones.

#### 1.N.1.1

Recognize numbers to 20 without counting (subitize) the quantity of structured arrangements. Clarification statement: Subitizing is defined as instantly recognizing the quantity of a set without having to count. Subitizing is not a vocabulary word and is not meant for student discussion at this age.

#### 1.N.1.2

Use concrete representations to describe whole numbers between 10 and 100 in terms of tens and ones.

#### 1.N.1.3

Read, write, discuss, and represent whole numbers up to 100. Representations may include numerals, addition and subtraction, pictures, tally marks, number lines and manipulatives, such as bundles of sticks and base 10 blocks.

#### 1.N.1.4

Count forward, with and without objects, from any given number up to 100 by 1s, 2s, 5s and 10s.

#### 1.N.1.5

Find a number that is 10 more or 10 less than a given number up to 100.

#### 1.N.1.6

Compare and order whole numbers from 0 to 100.

#### 1.N.1.7

Use knowledge of number relationships to locate the position of a given whole number on an open number line up to 20.

#### 1.N.1.8

Use objects to represent and use words to describe the relative size of numbers, such as more than, less than, and equal to.

#### 1.N.2

Solve addition and subtraction problems up to 10 in real-world and mathematical contexts.

#### 1.N.2.1

Represent and solve real-world and mathematical problems using addition and subtraction up to ten.

#### 1.N.2.2

Determine if equations involving addition and subtraction are true.

#### 1.N.2.3

Demonstrate fluency with basic addition facts and related subtraction facts up to 10.

#### 1.N.3

Develop foundational ideas for fractions.

#### 1.N.3.1

Partition a regular polygon using physical models and recognize when those parts are equal.

#### 1.N.3.2

Partition (fair share) sets of objects into equal groupings.

#### 1.N.4

Identify coins and their values.

#### 1.N.4.1

Identifying pennies, nickels, dimes, and quarters by name and value.

#### 1.N.4.2

Write a number with the cent symbol to describe the value of a coin.

#### 1.N.4.3

Determine the value of a collection of pennies, nickels, or dimes up to one dollar counting by ones, fives, or tens.
