Place Value (Tens and Ones) — Answer Key
Part A: Trace the Words
Trace each word carefully by following the dotted lines.
1. tens
2. ones
3. digit
4. value
5. place
6. number
Part B: Fill in the Blank
Write the missing word or number on each line.
1. The number 34 has 3 tens.
In 34, the first digit 3 is in the tens place, so the number has 3 tens (worth 30).
2. The number 27 has 7 ones.
In 27, the digit on the right (7) is in the ones place, so the number has 7 ones.
3. 5 tens and 2 ones make 52.
5 tens equals 50, and adding 2 ones gives 50 + 2 = 52, so the 5 goes in the tens place and 2 goes in the ones place.
4. The number 19 has 1 ten.
In 19, the digit 1 on the left is in the tens place, which is 1 ten worth 10.
Part C: True or False?
Read each statement. Circle True or False.
1. The number 46 has 4 tens.
True False
This is true because in 46 the digit 4 sits in the tens place, giving the number 4 tens (worth 40).
2. The number 83 has 8 ones.
True False
This is false because in 83 the 8 is in the tens place — the ones digit is 3, so 83 has 3 ones, not 8.
3. 3 tens and 5 ones make 35.
True False
This is true because 3 tens is 30 and 5 ones is 5, and 30 + 5 = 35.
