This document is the About the Cluster document created by the authors of the NC2ML Instructional Frameworks. Read this document prior to teaching the cluster in order to get insight into the clustering of the standards, mathematics to be taught, and important considerations.

This document is not remixable since the document has been written by creators of the NC2ML Instructional Frameworks.

Students will compare numbers using less than (<), greater than (>), and equal to (=),

This 2 unit of number and operations lessons explores place value through 6 hands-on activities and 2 worksheets.

This 2 unit of number and operations lessons explores numbers to 1,000 on a line or grid through 2 hands-on activities and 2 worksheets.

In this ordering task each number has at most 3 digits so that students have the opportunity to think about how digit placement affects the size of the number.

Students work in teams to follow criteria and constraints to design their own container that holds pompoms (popcorn). When this is completed they need to test and record how many pom-poms their container will hold. Students find that counting and organizing groups of ten is the best way to do this. They record their information on a data analysis sheet and the following day they compare their numbers and amounts.

This unit was created by the Rethink Education Content Development Team. This course is aligned to the NC Standards for 2nd Grade Math.

Students will compare two three-digit numbers based on the value of the hundreds, tens, and ones digits, using >, =, and < symbols and record the results of comparisons. NC.2.NBT.4: This standard calls for students to apply their knowledge of NC.1.NBT.1 and NC.1.NBT.3 by examining the value of the digits within two three-digit numbers in order to compare them.

This resource is from Tools4NCTeachers.A Common Formative Assessment (CFA) provides a snapshot of current student understanding. It serves as a checkpoint, and may be used to guide future whole and small group instruction. This CFA addresses 2nd grade, Cluster 4 standards.

The Family Letters are intended to be sent home at the beginning and middle of the cluster. They explain big ideas of the cluster using family-friendly language. Families can also find tips for working with their children at home, digital games, videos, and books. This file contains both English and Spanish versions of the Family Letters.

This resource is from Tools4NCTeachers.Math games are fun, motivating, and provide opportunities for students to build number concepts, reasoning, and fluency. These games may be used as math stations or as whole group learning opportunities. This file contains directions and materials for Cluster 4 math games

The intended purpose of this document is to provide teachers with a tool to determine student understanding and suggest instructional moves that may help guide a student forward in their learning. It is not an exhaustive list of strategies.

This resource is from Tools4NCTeachers. This file contains a set of 6 tasks (including scoring rubric and student recording sheet).  The tasks may be used for instruction or assessment.  Each task focuses on comparing 3-digit numbers, and using symbols (>,<, =) to make comparisons.Remix this resource to include student work samples or addtional tasks.

This resource is from Tools4NCTeachers.Students need distributed practice of newly-learned skills to develop fluency, build proficiency, and deepen understanding. This file contains directions for activities which may be used as Cluster 4 games or math stations.

This resource is from Tools4NCTeachers.In this lesson, small groups of students play a game where they spin 3-digit numbers, build them using arrow cards, and compare the numbers.  Several extension activities and math centers are shared in this lesson.

This resource is from Tools4NCTeachers.In this lesson, students play a game that requires the comparing and adding of numbers.  The game also provides an opportunity requires record numbers in both standard and expanded form.  Remix this lesson to provide extension activities or pictures of student work.

Using the procedure of the "20 Questions" game, students will generate questions to deduce the "secret number" chosen on the hundreds board. Students will use many of the mathematical practices of the Common Core State Standards in order to generate their questions.

For this task, students compare three digit numbers and explain their comparisons using pictures.
