• 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 Geometry & Measurement

• 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.D Data & Probability

• 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.
