This Mathematics unit addresses a range of place value concepts involving 5-digit numbers.

It consists of 7 lessons of approximately 60 minutes duration.

The sequence of lessons and suggested time framesย should be regarded as a guide only; teachers should pace lessons in accordance with the individual learning needs of their class.

An assessment task for monitoring student understanding of the unit objectives is included andย will require an additional lesson.

### Overview

#### Objectives

• To introduce place value in the tens of thousands.
• To further explore place value in the ten thousands place.
• To investigate how place value can be used to decompose numbers into smaller parts.
• To investigate how place value can be used to expand numbers.
• To round 5-digit numbers to the nearest 10; 100; and 1,000.
• To multiply and divide larger numbers by 10 and 100.
• To compare and order 5-digit numbers.

#### Preparing for Learning

Prior to beginning the unit, develop a place value display in the classroom. Display posters,ย word wall vocabulary,ย and learning goals that the students will engage with throughout the unit to stimulate their learning. For examples of such resources, browse the Place Value categoryย on the Teach Starter website.

There are many concepts to address within the topic of 5-digit place value. Theย lessons in this unit cover a range of these concepts, many of which haveย varying degrees of complexity. Teachers are encouraged to selectย lessons from the unit that best suit the learning needs of their students, or to adapt lessons accordingly.

Some of the resources which accompany this unit plan will need to be prepared prior to teaching. For this reason, it is advised that teachers browse through all lessons before starting the unit.

Additional note: Some of the topics included in this unit of work are also addressed in the Exploring 4-Digit Place Value Unit Plan. If you are teaching a cohort of students who have already completed the 4-digit unit, they may already be familiar with some of the activities and teaching resources used within the 5-digit unit.

#### Common Core Curriculum alignment

• CCSS.MATH.CONTENT.4.NBT.A.1

Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right. For example, recognize that 700 รท 70 = 10 by applying concepts of place value and division.

• CCSS.MATH.CONTENT.4.NBT.A.2

Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.

• CCSS.MATH.CONTENT.4.NBT.A.3

Use place value understanding to round multi-digit whole numbers to any place.
