Part B: Fill in the Blank
Write the missing number on each line.
1. The value of the 5 in 52 is 50.
The digit 5 is in the tens place, so its value is 5 x 10 = 50.
2. A number has 8 tens and 1 one. The number is 81.
8 tens = 8 x 10 = 80, plus 1 one = 81.
3. In the number 64, the digit 6 means 6 tens.
In 64, the tens digit is 6 and the ones digit is 4.
4. 30 + 7 = 37.
37 minus 30 equals 7, so the missing ones value is 7.
5. 90 + 4 = 94.
94 minus 4 equals 90, so the missing tens value is 90.
