### 1.N Number & Operations

- 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.
- 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.1.5 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.

### 1.A Algebraic Reasoning & Algebra

- 1.A.1 Identify patterns found in real-world 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.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.
