Welcome to the learning progression for Second Grade. This progression incorporates the overall topics of this grade-level's mathematics and is formatted with Overarching Questions, Essential Questions, and Big Ideas for each unit. This progression model takes the work of bundling standards to the next level by grouping together grade-level concepts in the Big Ideas sections. The Big Ideas are designed to represent the critical mathematics of this grade level in a manner that is more coherent and productive as a guide for planning instruction, assessment, and intervention. Big Ideas are for progression and planning and are not a replacement for the OAS-M objectives.
The use of an asterisk (*) indicates an objective is repeated in another unit or an objective that is partially taught in a unit and will be taught in its entirety in a later unit. The parts of the objective that will be taught in a later unit is indicated by the “strikethroughs.” Occasionally, new words are added to the objective to ensure the objective still makes sense considering the strikethroughs.

Unit 1: Developing Place Value Concepts Timing 5-6 weeks Objectives |
How does place value help us understand number relationships? |
|
|
2.N.1.1 Read, write, discuss, and represent whole numbers up to 1,000. Representations should include, but are not limited to, numerals, words, pictures, tally marks, number lines, and manipulatives. 2.N.1.2 Use knowledge of number relationships to locate the position of a given whole number, up to 100, on an open number line. 2.N.1.3 Use place value to describe whole numbers between 10 and 1,000 in terms of hundreds, tens, and ones, including written, standard, and expanded forms. Know that 10 is equivalent to 10 ones and 100 is equivalent to 10 tens. 2.N.1.4 Find 10 more or 10 less than a given three-digit number. Find 100 more or 100 less than a given three-digit number. 2.N.1.5 Use objects to determine whether a number is even or odd. 2.N.1.6 Use place value understanding to round numbers to the nearest ten and nearest hundred (up to 1,000). Recognize when to round in real-world situations. 2.N.1.7 Use place value to compare and order whole numbers up to 1,000 using comparative language, numbers, and symbols (e.g., 425 > 276, 73 < 107, page 351 comes after page 350, 753 is between 700 and 800). |
Unit 2: Applying Place Value to Patterns and Data
Timing 3-4 weeks Objectives
|
How do patterns and graphs explain real-world situations? |
|
|
2.A.1.1 Represent, create, describe, complete, and extend increasing and decreasing patterns with quantity and numbers in a variety of contexts. 2.A.1.2 Represent and describe repeating patterns involving shapes in a variety of contexts 2.D.1.1 Explain that the length of a bar in a bar graph and the number of objects in a pictograph represents the number of data points for a given category. 2.D.1.2 Organize a collection of data with up to four categories using pictographs and bar graphs in intervals of 1s, 2s, 5s or 10s. 2.D.1.3 Write and solve one-step word problems involving addition or subtraction using data represented within pictographs and bar graphs with intervals of one. 2.D.1.4 Draw conclusions and make predictions from information in a pictograph and bar graph. |
Unit 3: Developing Place Value in Operations Timing 5-6 weeks Objectives |
How does understanding place value aid in whole number operations? |
|
|
2.N.2.1 Use the relationship between addition and subtraction to generate basic facts with sums and minuends of up to 20. 2.N.2.2 Demonstrate fluency with basic facts of addition and subtraction with sums and minuends of up to 20. 2.N.2.3 Estimate sums and differences up to 100. 2.N.2.4 Use strategies and algorithms based on knowledge of place value and equality to add and subtract two-digit numbers. 2.N.2.5 Solve addition and subtraction problems involving whole numbers up to two digits. 2.N.2.6 Use concrete models and structured arrangements, such as repeated addition, arrays, and ten frames to develop an understanding of multiplication. |
Using Place Value in Algebraic Reasoning Timing 3-4 weeks Objectives |
How do we use equivalence to describe our world? |
|
|
2.A.2.1 Use objects and number lines to represent number sentences. 2.A.2.2 Generate models and situations to represent number sentences and vice versa. 2.A.2.3 Apply the commutative property, identity property, and number sense to find values for unknowns that make addition and subtraction number sentences true or false.
|
Unit 5: Geometry, Partitioning, and Time Timing 4 weeks Objectives
|
Why would we divide something into equal parts? |
|
|
2.GM.1.1 Recognize regular and irregular trapezoids and hexagons. 2.GM.1.2 Describe, compare, and classify two-dimensional figures according to their geometric attributes. 2.GM.1.3 Compose and decompose two-dimensional shapes using triangles, squares, hexagons, trapezoids, and rhombi. 2.GM.1.4 Sort three-dimensional shapes based on attributes such as number of faces, vertices, and edges. 2.GM.1.5 Recognize right angles and classify angles as smaller or larger than a right angle. 2.GM.3.1 Distinguish between a.m. and p.m. 2.GM.3.2 Read and write time to the quarter hour on an analog and digital clock. 2.N.3.1 Identify the parts of a set and area that represent fractions for halves, thirds, and fourths. 2.N.3.2 Construct equal-sized portions through fair sharing (length, set, and area models for halves, thirds, and fourths).
|
Timing 5-6 weeks Objectives |
How can we use multiple representations to make sense of the world?
|
|
|
2.N.4.1 Determine the value of a collection of coins up to one dollar using the cent symbol. 2.N.4.2 Use a combination of coins to represent a given amount of money up to one dollar. 2.GM.2.1 Explain the relationship between the size of the unit of measurement and the number of units needed to measure the length of an object. 2.GM.2.2 Explain the relationship between length and the numbers on a ruler by using a ruler to measure lengths to the nearest whole unit. 2.GM.2.3 Explore how varying shapes and styles of containers can have the same capacity.

How are multiplication and division related? |
|
This unit is intended to stretch above second grade standards into third grade. Some of the tasks in this unit will use third grade standards to develop the connection between multiplication and division. Each task will allow students to use manipulatives and models to problem solve.
