Free Worksheets for CCSS.Math.Content.1.NBT.B.2

As a first-grade teacher or parent, you know how crucial it is to build a strong foundation in mathematics. One of the key areas of focus in the first-grade curriculum is Number and Operations in Base Ten (NBT). We’ll pay particular attention to the Common Core State Standard CCSS.Math.Content.1.NBT.B.2, which focuses on understanding place value in two-digit numbers. Workybooks digital library will introduce you to a variety of free, printable worksheets that can help your students or children master these essential concepts.

Why NBT is Important

Number and Operations in Base Ten form the backbone of early mathematics education. These skills help students understand place value, which is fundamental to all future math learning. Mastering NBT concepts, especially those outlined in CCSS.Math.Content.1.NBT.B.2, provides students with a solid foundation for understanding our base-ten number system. It teaches them to:

• See multiples of 10 (20, 30, 40, etc.) as representing groups of tens
• Recognize 10 as a bundle of ten ones
• Understand that numbers 11-19 are composed of a ten and some ones

What NBT Covers in First Grade

CCSS.MATH.CONTENT.1.NBT.B.2 – Understanding Place Value

In this standard, students learn that a two-digit number represents amounts of tens and ones. For example, 34 represents three tens (30) and four ones (4). Place value is essential for understanding how numbers work.

CCSS.MATH.CONTENT.1.NBT.B.2.a – Tens as Bundles

This standard extends the concept of place value by teaching students to recognize that ten ones can be grouped together to make a “bundle” of ten. This helps students better understand how larger numbers are formed.

Tens as Bundles (1.NBT.B.2.a)

Worksheet: “Making Bundles of Ten” In this hands-on worksheet, students use pictures of objects (e.g., apples, stars) and group them into sets of ten. This worksheet emphasizes the concept that ten ones can be combined into a single ten.

In this first-grade common core math worksheet, students are tasked with counting the number of tens and ones in each group. This exercise reinforces the concept of place value and helps develop number sense and counting skills.

CCSS.MATH.CONTENT.1.NBT.B.2.b – Recognizing Tens in Larger Numbers

In this standard, students understand that numbers from 11 to 19 consist of one ten and additional ones, while numbers from 20 to 90 consist of tens and ones (e.g., 70 = seven tens and zero ones).

Worksheet: “Counting Tens and Ones” Students work with numbers from 11 to 99, identifying how many tens and how many ones each number contains. For example, they will decompose 58 into five tens and eight ones.This interactive and printable worksheet, “Counting Tens and Ones” worksheet is a valuable resource for students learning to count and group objects into tens and ones. It reinforces the crucial skill of recognizing and understanding place value, a foundational concept in the number system.

In this worksheet, students are presented with images of fish scattered across the page. They are instructed to circle groups of ten fish and count the remaining ones. This hands-on activity allows them to visualize and physically group objects, solidifying their understanding of place value.

This common core math worksheet, is designed to help students understand and practice place value concepts, specifically tens. The worksheet features a farmyard scene with various animals, each displaying a two-digit number. Students are prompted to answer questions related to identifying the number of tens represented by each animal.Furthermore, the interactive version of this worksheet allows students to engage with the content online, providing an immersive learning experience. Alternatively, the printable PDF format enables students to complete the worksheet by hand, offering a more traditional approach.

Board game for CCSS.Math.Content.1.NBT.B.2

This interactive and printable worksheet, “Tens Game” board game is an engaging and interactive activity designed to help students develop a strong understanding of place value and number sense. This printable or online worksheet presents a game board with numbered spaces, and students roll a die to move forward or backward based on the tens digit of the number they land on.

As students navigate through the game, they reinforce their knowledge of tens and ones place values, practice counting and recognizing patterns, and develop strategic thinking skills. The game format adds an element of fun and excitement, making the learning process more enjoyable and memorable.

This resource is suitable for first-grade students and aligns with the Common Core State Standards for Mathematics, specifically addressing the 1.NBT.B.2.C standard, which focuses on understanding place value and comparing two-digit numbers using the greater than, less than, and equal to symbols.

Remember, while worksheets are useful, they should be part of a well-rounded math education that includes manipulatives, group work, and real-world problem-solving. Happy teaching!
