This resource is from Tools4NCTeachers.In this lesson, students develop an understanding of place value by using arrow cards.  The focus of this lesson is on writing numbers using expanded form.Arrow cards are place value cards with an "arrow" or point on the right side.  Students can organize the cards to represent numbers in expanded notation. OR, they can overlap cards and (lining up the arrows) to form multi-digit numbers. Printable arrow cards are provided with this resource.. 

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.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."Launch, Explore, Discuss" is a research-based lesson framework where students grapple with a task and then come together to share strategies used.  The introduction of new strategies is delayed until after grappling.  This is the primary lesson framework for the Tools4Teachers lessons. This resource serves as a professional development tool, explaining the benefits of this lesson framework and outlining each component.

This resource is from Tools4NCTeachers.  this lesson, students will count items in order to determine how many groups of tens are needed to make 100, 200, 300...  The students will determine the pattern of how many tens make a hundred and use that pattern to determine how many tens are needed to make 400, 500, 600, 700, 800, and 900.  Lesson comes with printable materials.  Remix this lesson to provide extension ideas or samples of student work. 

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. This file contains a set of 8 tasks (including scoring rubric and support materials).  The tasks may be used for instruction or assessment.  The tasks focus around representing, interpreting and reading 3-digit numbers based on place value.Remix this resource to include student work samples or addtional tasks.

This resource is from Tools4NCTeachers.In this lesson, students explore 700-799 by drawing cards and placing them correctly on a hundreds “sheet” labeled with only the numbers 700 and 799. 

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.

This resource is from Tools4NCTeachers.In this lesson, students spin spinners containing 3-digit numbers.  Then, students use their 1000 boards to find sums of the numbers they spun.  There are a variety of spinners provided in order to allow for differentiation.

The purpose of this task is to help students understand composing and decomposing ones, tens, and hundreds. This task is meant to be used in an instructional setting and would only be appropriate to use if students actually have base-ten blocks on hand.

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.
