1.NO Number and Operations

1.1 Understand and represent relationships among numbers and compute operations (addition and subtraction) with and without manipulatives.
1.1.a Recognize and write numbers 0 to 100.
1.1.b Compose and decompose two-digit numbers with representations in words and physical models.
1.1.c Explain how to compare and order two-digit numbers using the terms "more," "less," "greater than," "less than," "equal to," and "almost," and the symbols >, <, and =.
1.1.d Use multiple representations for addition (combining of sets) and subtraction (take-away, missing addend, comparison) to solve problems.
1.1.e Find the sums of 3 single-digit addends (for example: 3 + 6 + 2 =11).
- Addition: Adding three numbers (First grade - B.12)
- Addition: Word problems - adding three numbers (First grade - B.13)
1.1.f Justify addition and subtraction of two-digit whole numbers without regrouping.
1.1.g Find equal money amounts with different coin combinations up to $0.25.
- Money: Equivalent coins I (First grade - N.4)
1.1.h Identify the value of coins (penny, nickel, dime, quarter).
1.1.i Determine the value of like coins up to $1.00.
1.1.j Find the value of mixed coins up to $1.00.

1.ALG Algebra

1.2 Recognize, extend, and create patterns.
1.2.a Use a pattern rule to translate and recognize patterns from one pattern representation to another.
1.2.b Formulate, explain, and generalize patterns within and across addition and subtraction.
- Counting and number patterns: Sequences - count up and down by 1, 2, 3, 5, and 10 (First grade - A.14)
1.2.c Model situations and solve equations that require addition and subtraction of whole numbers; use objects, pictures, and symbols.
1.2.d Count by different units when given a group of objects using 1's, 2's, 5's, and 10's.

1.GEO Geometry

1.3 Identify and classify properties of two- and three-dimensional shapes.
1.3.a Identify and classify two-dimensional figures (triangle, square, rectangle, circle, trapezoid, hexagon, and rhombus).
- Geometry: Identify 2-dimensional shapes (First grade - J.1)
1.3.b Identify and classify three-dimensional figures (cube, rectangular prism, and sphere) according to their characteristics.
- Geometry: Identify 3-dimensional figures (First grade - J.2)
- Geometry: Geometry of everyday objects (First grade - J.3)
1.3.c Explain the part-whole relationships resulting from the composition or decomposition of plane and solid figures.
- Geometry: Relate planar and solid figures (First grade - J.4)

1.MEA Measurement

1.4 Identify and apply measurable attributes.
1.4.a Use nonstandard units (paper clips, unifix cubes, etc.) and standard units (inches, centimeters) to measure length.
- Measurement: Which unit of length is appropriate? (First grade - M.2)
- Measurement: Units of length: word problems (First grade - M.3)
1.4.b Compare weight of objects using a balance scale with and without nonstandard units.
