This is one possible method for using the area model for division.

With this division strategy, students divide by breaking the dividend into its expanded form. Then, students use familiar multiplication facts to divide. It is suggested that this would be the first of three strategies for division (preceding partial quotients and the standard algorithm.

This is from Tools for NC Teachers. Students explore the value of a group of one type of coin and consider how changing the value of the coins changes the value of the group. This is remixable.

In this lesson students use the open number and various strategies to solve two-step story problems.

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.

This lesson is from Tools for NC Teachers. In this lesson, students will use base-ten blocks to build models of numbers including 10,000. The intention is to help students understand our base-ten place value system and explain that a digit in the ones place represents 10 times as much as it represents in the place to its right. This is remixable.

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 if from Tools4NCTeachers.In this lesson, students use number cards to build numbers and write them in both standard and expanded form.  Printable materials, suggestes for differentiation, and assessment probes are provided.  Remix to share ideas for turning this lesson into a math station or game. 

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.

In this lesson, students build fluency with recognizing and creating representations of numbers within 100. Students deepen their place value understanding as they work with ten frame cards. There are several variations built into the lesson for number ranges and response options.

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.

In this lesson, students use ten frames to represent and compare two-digit numbers.

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.
