Grade 2: Numerical Reasoning – Counting Within 1000, Place Value, Addition and Subtraction, Fluency To 20, Developing Multiplication Through Arrays

2.NR.1

Using the place value structure, explore the count sequences to represent, read, write, and compare numerical values to 1000 and describe basic place-value relationships and structures.

2.NR.1.1

Fully covered
Explain the value of a three-digit number using hundreds, tens, and ones in a variety of ways.

2.NR.1.2

Partially covered
Count forward and backward by ones from any number within 1000. Count forward by fives from multiples of 5 within 1000. Count forward and backward by 10s and 100s from any number within 1000. Count forward by 25s from 0.

2.NR.1.3

Fully covered
Represent, compare, and order whole numbers to 1000 with an emphasis on place value and equality. Use >, =, and < symbols to record the results of comparisons.

2.NR.2

Apply multiple part-whole strategies, properties of operations and place value understanding to solve real-life, mathematical problems involving addition and subtraction within 1,000.

2.NR.2.1

Mostly covered
Fluently add and subtract within 20 using a variety of mental, part-whole strategies.

2.NR.2.2

Partially covered
Find 10 more or 10 less than a given three-digit number and find 100 more or 100 less than a given three-digit number.

2.NR.2.3

Mostly covered
Solve problems involving the addition and subtraction of two-digit numbers using part-whole strategies.

2.NR.2.4

Mostly covered
Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.

2.NR.3

Work with equal groups to gain foundations for multiplication through real-life, mathematical problems.

2.NR.3.1

Not covered
Determine whether a group (up to 20) has an odd or even number of objects. Write an equation to express an even number as a sum of two equal addends.

2.NR.3.2

Mostly covered
Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends.
