Value Voyage Lesson Plan The Great Value Voyage
Instructional Facilitation Guide
4th Grade
60 Minutes
Mission Objective
Students will be able to identify the place value of digits from ones to millions and understand the relationship between different place values in the base-10 system. They will visualize how 10 of one unit forms 1 of the next larger unit.
The "Why"
"Understanding place value is crucial for all future math skills, from addition and subtraction to multiplication, division, and working with decimals. It helps students make sense of large numbers they encounter in everyday life."

The Voyage Itinerary
05
Warm-Up: Number Scramble
Identify value hierarchy.
• Display scrambled digits (e.g., 2, 5, 8, 1 ) on the board.
• Task students to create the largest and smallest possible 4-digit numbers.
• Discussion: "Why did you put the 8 in the thousands place for the largest number? What would happen if we moved it?"
10
Introduction: The Voyage Begins!
Slide Deck Guided Discussion.
• Launch the Voyage Through Number Lands Slide Deck .
• Introduce "Place Power": The value of a digit is dictated by its position.
• Emphasize the Base-10 pattern (moving left = 10x bigger).
20
Building Challenge
Hands-on with Base Ten Blocks.
• Distribute blocks and the Base Ten Building Challenge Activity .
• Trading Up: Focus on the transition from 10 ones to 1 ten, and 10 tens to 1 hundred.
• Encourage students to "draw" their numbers using standard notations (square for hundred, line for ten, dot for one).
15
Mapping the Journey
Independent practice.
• Students work through the Map Your Number's Journey Worksheet .
• Circulate: Watch for students confusing "place" (name) with "value" (amount).
• Peer Check: Have students compare Part 3 (Expanded Form) with a partner.
10
Conclusion & Discovery
Reflection and cool-down.
• Recap: Thousands Period and the role of the comma.
• Students complete the Discovery Cool-Down .
• Exit Ticket: Ask one volunteer to name their "7-digit discovery" number and the value of its highest place.
Voyage Through Number Lands Slides Set Sail!
Welcome, Value Voyagers!
Ready for an adventure into the world of numbers? Today, we're going on The Great Value Voyage to discover how numbers get their power!
Welcome students. Ask: "Have you ever noticed how the same digit can mean something totally different?"
What is Place Value?
Imagine each number as a special agent, and its place determines its power!
The same digit has different values depending on where it sits.
Our number system is built on groups of TEN!
5 2 5
Is the 2 in 25 the same as the 2 in 255?
Explain 'base-10'. Moving left = multiplying by 10. Use visual examples on board (1, 10, 100).
The First Stops
Ones
Counts single items. The smallest building block!
Tens
Groups of 10 ones. A major step up!
Hundreds
Groups of 10 tens (or 100 ones). Entering the big leagues!
Ask: "What is the value of the '3' in 321? How about the '2' in 123?"
The Thousand Islands
THOUSANDS
Groups of 10 hundreds.
1,000
Ten Thousands
Groups of 10 thousands.
10,000
45,201
Thousands Period
Ones Period
Notice the comma separating the groups!
Emphasize the comma. It helps us "read" the large numbers by periods.
Reaching New Heights
HUNDRED THOUSANDS
Groups of 10 Ten Thousands
100,000
THE MILLIONS
10 Hundred Thousands!
1,000,000
Current Location:
7,452,301
That's SEVEN MILLION items!
Explain that each 'period' has three places. Commas are like stop-signs for units.

Big Cubes
GOLDEN RULE: 10 of one block = 1 of the next!
Transition to Activity. Emphasize physical trades (10 cubes for 1 rod).

Part 1: Building Basics
Construct each number using your blocks. Check off the box once built.
Build 23
How many rods? How many cubes?
Build 47
How many rods? How many cubes?
Build 105
What happens to the tens place?
Build 238
Show the correct hundreds, tens, and ones.

Part 2: Trading Up!
1. Start with 12 ones blocks.
Can you trade for a ten rod? If so, how many ones do you trade?
What number have you built now?
2. Start with 15 tens rods.
How many tens do you trade for a hundred flat?
What number have you built now?
3. Start with 23 ones, 4 tens, and 1 hundred.
Trade your ones. How many tens did you add?
Trade your tens. Did you get a new hundred?
What is the final number?

Part 3: Challenge Numbers!
Use your blocks to build these larger numbers. Draw a quick sketch of what you built (use squares for hundreds, lines for tens, and dots for ones).

II
Part 2: Place It Right!
Identify the specific digit that sits in the requested place.
In 34,567, what digit is in the thousands place?
In 123,098, what digit is in the hundred thousands place?
In 5,678,901, what digit is in the millions place?
In 90,876, what digit is in the tens place?
In 2,001, what digit is in the hundreds place?

Part 3: Expanded Adventures!
Write each number in expanded form (e.g., 25 = 20 + 5).

Part 4: Building Numbers
Assemble the digits back into their standard form.
500 + 40 + 7 =
2,000 + 300 + 90 + 1 =
(7 x 100,000) + (1 x 10,000) + (0 x 1,000) + (5 x 100) + (8 x 10) + (2 x 1) =
(4 x 1,000,000) + (6 x 100,000) + (2 x 1) =
