The Challenge
Maya has 3 thousands, 14 hundreds, 6 tens, and 5 ones.
What number did Maya build in all? Explain how you regrouped the extra hundreds.
Thousands
3
Hundreds
14
Tens
6
Ones
5
My Solution & Reasoning
1. Regroup the 14 Hundreds:
14 hundreds = thousand + hundreds
2. Total Number Built:
Standard Form:
3. How I know:
Prerequisite Focus: Regrouping place-value units Slide 1 of 7

Standard, Word & Expanded Form
Name: Date:
The Challenge
A wildlife sanctuary rescued 4,078 sea turtle hatchlings this season.
Show this number in both expanded form and word form. Watch out for the zero!
Number Spotlight 4,078 Pay attention to the value of each digit!
Record All Forms
1. Expanded Form (sum of the values):
2. Word Form (spelled correctly):
Why do we not need to write a term for the hundreds place in expanded form?

Digit Value & Adjacent Places
Name: Date:
The Challenge
Look closely at the number 5,520.
Both marked digits are fives, but they live in different places! Compare their actual values.

Thousands Hundreds Tens Ones
Value Comparison
Value of Thousands 5:
Value of Hundreds 5:
Complete the sentence:
The 5 in the thousands place is times the value of the 5 in the hundreds place.
Explain how place value creates this relationship:
Prerequisite Focus: 10× relationship between neighboring place values Slide 3 of 7

Comparing & Ordering Numbers
Name: Date:
The Challenge
Compare the numbers 6,482 and 6,428 using >, <, or =.
Explain which specific place value allowed you to decide which number is greater.
Place-by-Place Lineup:
Th
6 = 6
H
4 = 4
Tens
8 vs 2
Ones
2 vs 8
My Comparison & Proof
Write >, <, or = in the circle:
6,482
6,428
Which place value decided the comparison?
Name of place value:
Explain your strategy in complete sentences:
Prerequisite Focus: Comparing greatest place values first Slide 4 of 7

Number Lines & Benchmark Reasoning
Name: Date:
The Challenge
Plot the number 3,750 on the number line below.
Step 1: Mark midpoint • Step 2: Plot 3,750
3,000
Midpoint: [ ____ ]
4,000
1. What is the exact midpoint number?
Midpoint =
2. How do you know 3,750 is to the right of the midpoint?
Because 3,750 is...
Prerequisite Focus: Positioning multi-digit numbers between thousands Slide 5 of 7

Powers of Ten & Place Value Shifts
Name: Date:
The Challenge
Solve 46 × 10.
Explain what happens to the place value of each digit when multiplied by 10. Why is there a zero in the ones place?
Place Value Shift (×10)
Hundreds
4
Tens
6
Ones
0
Each digit shifts 1 place to the left!
My Answer & Explanation
46 × 10 =
What happened to the 4 tens?
4 tens × 10 = 40 tens = hundreds
What happened to the 6 ones?
6 ones × 10 = 60 ones = tens
Why must we write a 0 in the ones place?
Prerequisite Focus: Understanding why multiplying by 10 shifts digits Slide 7 of 7
