Lesson seeds are ideas that can be used to build a lesson aligned to the CCSS. Lesson seeds are not meant to be all-inclusive, nor are they substitutes for instruction. When developing lessons from these seeds, teachers must consider the needs of all learners. It is also important to build checkpoints into the lessons where appropriate formative assessment will inform a teachers instructional pacing and delivery.

### Unit Overview

In prior grades, students used various strategies to multiply. This unit builds on prior understandings of multiplying whole numbers fluently which means a correct answer in a reasonable amount of steps. The unit focuses on performing whole number division using equations, arrays and concrete models. Addition, subtraction, multiplication, and division of decimals to hundredths should be used with concrete models or drawings and strategies relating the strategy to a written method and explaining the reasoning used.

**Enduring Understandings:**

At the completion of this unit performing operations with multi-digit whole numbers and with decimals to hundredths:

**Focus Standards (Listed as Examples of Opportunities for In-Depth Focus in the PARCC Content Framework document):**

**5.NBT.B.6**UThe extension from one-digit divisors to two-digit divisors requires care. This is a major milestone along the way to reach fluency with the standard algorithm in grade 6.

**Possible Student Outcomes:**The student will be able to:

Interdisciplinary connections fall into a number of related categories:

**Sample Assessment Items:**

The items included in this component will be aligned to the standards in the unit and will include:

**Interventions/Enrichments/PD: ***(Standard-specific modules that focus on student interventions/enrichments and on professional development for teachers will be included later, as available from the vendor(s) producing the modules.)*

**Vocabulary/Terminology/Concepts: ***This section of the Unit Plan is divided into two parts. Part I contains vocabulary and terminology from standards that comprise the cluster, which is the focus of this unit plan. Part II contains vocabulary and terminology from standards outside of the focus cluster. These “outside standards” provide important instructional connections to the focus cluster.*

**Part I – Focus Cluster**

**Perform Operations with Multi-Digit Whole Numbers and with Decimals to Hundredths **

** NOTE: None of the vocabulary, terminology, and concepts in this cluster are new, nor should they be particularly problematic for instruction of the related standards. **

**Part II – Instructional Connections outside the Focus Cluster**

** NOTE: None of the vocabulary, terminology, and concepts in this cluster are new, nor should they be particularly problematic for instruction of the related standards. **
