Place Value (Tens and Ones) — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. Which number has 6 tens and 2 ones?
A) 26
B) 62
C) 46
D) 36
6 tens equals 60 and 2 ones equals 2, so 60 + 2 = 62, which puts the 6 in the tens place and 2 in the ones place.
2. What is the expanded form of 85?
A) 80 + 5
B) 50 + 8
C) 8 + 5
D) 85 + 0
Expanded form breaks a number into its place values, so 85 splits into 8 tens (80) plus 5 ones, written as 80 + 5.
3. In the number 47, what is the value of the digit 4?
A) 4
B) 7
C) 40
D) 47
The 4 in 47 sits in the tens place, so its value is 4 tens, which equals 40.
4. Which number is the same as 30 + 9?
A) 93
B) 39
C) 309
D) 13
30 is 3 tens and 9 is 9 ones, so combining them gives the number 39.
Part B: Fill in the Blank
Write the correct answer on each line.
1. The number 57 has 5 tens.
In 57, the digit 5 is on the left in the tens place, so the number has 5 tens worth 50.
2. If you add 1 more ten to 34, you get 44.
Adding 1 ten means adding 10, so 34 + 10 = 44 — the tens digit goes up from 3 to 4 while the ones stay at 4.
3. 90 + 6 = 96.
90 is 9 tens and 6 is 6 ones, so 9 tens and 6 ones together make the number 96.
4. The digit in the ones place of 71 is 1.
The ones place is always the digit on the right, and in 71 that digit is 1.
5. The largest two-digit number is 99.
99 is the biggest two-digit number because it uses the largest digit (9) in both the tens and ones place.
