# 2nd Grade Skills in Math

The 2nd Grade Skills below are based on the Common Core Standards For Mathematics. You can find out more about the Common Core Standards here.

You will also find a listing of related math resources (worksheets, charts, etc) here.

Note: Math standards and curricula can vary by location or school. Check with your child’s school to determine what 2nd grade math skills are expected in your location.

## Operations & Algebraic Thinking

Solving one and two-step word problems using adding and subtracting with numbers up to 100.

The listing of worksheets and other math resources below are related to the following standard extracted from the Common Core Standards For Mathematics:

Use addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.

### Word problems

Adding and subtracting with fluency with numbers to 20 using strategies. (e.g. making ten 8 + 5 = 8 + 2 = 10 + 3 = 13) and memorizing addition facts for single-digit numbers (e.g. up to 9 + 9 = 18)

The listing of worksheets and other math resources below are related to the following standard extracted from the Common Core Standards For Mathematics:

Fluently add and subtract within 20 using mental strategies. By end of Grade 2, know from memory all sums of two one-digit numbers.

### Worksheet Generator

Identifying groups as having either an odd or an even number of objects.

The listing of worksheets and other math resources below are related to the following standard extracted from the Common Core Standards For Mathematics:

Determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends.

### Number line

Writing equations (e.g. 4 + 4 + 4 + 4) to show how adding can be used to determine the number of objects in a rectangular array.

## Number & Operations in Base Ten

Recognizing that, for 3-digit numbers, the digits represent the amount of ones, the amount of tens, and the amount of hundreds.

The listing of worksheets and other math resources below are related to the following standard extracted from the Common Core Standards For Mathematics:

Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones. Understand the following as special cases:
1. 100 can be thought of as a bundle of ten tens – called a “hundred.”
2. The numbers 100, 200, 300, 400, 500, 600, 700, 800, 900 refer to one, two, three, four, five, six, seven, eight, or nine hundreds (and 0 tens and 0 ones).

### Worksheet Generator

Counting up to one thousand and skip counting by fives, tens, and by hundreds.

The listing of worksheets and other math resources below are related to the following standard extracted from the Common Core Standards For Mathematics:

Count within 1000; skip-count by 5s, 10s, and 100s.

### Worksheet Generator

Writing and reading number names up to one thousand and use expanded form. e.g. 876 = 800 + 70 + 6

The listing of worksheets and other math resources below are related to the following standard extracted from the Common Core Standards For Mathematics:

Read and write numbers to 1000 using base-ten numerals, number names, and expanded form.

### Worksheet

Comparing two 3-digit numbers by examining the hundreds, tens, and ones place in turn and correctly using the greater than, less than, and equal signs.

The listing of worksheets and other math resources below are related to the following standard extracted from the Common Core Standards For Mathematics:

Compare two three-digit numbers based on meanings of the hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons.

### Worksheet

Adding and subtracting with fluency up to 100.

The listing of worksheets and other math resources below are related to the following standard extracted from the Common Core Standards For Mathematics:

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

### Worksheet Generator

Adding as many as four 2-digit numbers.

The listing of worksheets and other math resources below are related to the following standard extracted from the Common Core Standards For Mathematics:

Add up to four two-digit numbers using strategies based on place value and properties of operations.

### Three or more

Adding and subtracting with numbers up to 1000 using place-value-based strategies including regrouping 10s and 100s when necessary.

The listing of worksheets and other math resources below are related to the following standard extracted from the Common Core Standards For Mathematics:

Add and subtract within 1000, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method. Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.

### Worksheet Generator
