Second Grade Number and Operations in Base Ten Standards Aligned Resources

Second Grade Math Domain: Number and Operations in Base Ten

In this domain, Second Grade students will continue expanding their knowledge in place value and counting. They’ll also be introduced to brand-new concepts, like counting by 5’s and comparing three-digit numbers. With supplemental learning resources from eSpark Learning, students can become more proficient in each standard while engaging with fun, interactive games and videos. Here’s a closer look at the Common Core standards within this domain:

2.NBT.1.a

Place Value

In this standard, second-graders will learn the concept of ‘bundles of tens’ when it comes to three-digit numbers.

2.NBT.1.b

Place Value

Expanding on the standard above, students will determine that 100 equals ten 10’s and so on and so forth.

2.NBT.2

Skip Counting by 5's

Students will learn how to count-skip by 5’s — all the way to 1,000. 

2.NBT.3

Numbers to 1000

In this standard, second-graders will become proficient in numbers 0 through 1,000, learning to read and write numerals, number names, and their expanded forms.

2.NBT.4

Compare 3-Digit Numbers

Students will work with less than, greater than, and equal to signs to compare three-digit numbers.

2.NBT.5

Add and Subtract within 100

Students will expand their use of mental strategies to begin adding and subtracting within 100. 

Get Started with Second Grade Number and Operations in Base Ten Learning Resources

Number and Operations in Base Ten is one of four domains included in the Second Grade math standards. During this phase of learning, students will learn concepts like:

  • Place value and bundles of tens
  • Skip counting by 5’s
  • Read and write numbers up to 1,000
  • Compare three-digit numbers using >, <, and = symbols
  • Add and subtract within 100 fluently

For each standard, eSpark Learning provides several resources and activities that are aligned to each. Through instructional videos, games, and practice assessments, second-graders can expect to become more proficient in each standard and learn at a rate of 1.5 times faster than their peers. 

Here’s a closer look at some of the standards-aligned eSpark Learning activities within the Number and Operations in Base Ten domain:

2.NBT.1.a
