Determine if statements about place value are true or false. Learn to avoid common mistakes.
Master these essential place value skills aligned with 1st grade standards
Two-digit numbers are made up of 'some tens' plus 'some ones'. For example, 16 is 1 ten (10 sticks bundled) plus 6 ones (6 individual sticks).
Example:
16 = 1 ten + 6 ones = 10 + 6 = 16
In the number 32, '3' is in the tens place and represents 3 tens (30), while '2' is in the ones place and represents 2 ones (2).
Example:
32 = 3 tens + 2 ones = 30 + 2 = 32 (not 3 + 2 = 5)
Common mistake: '47 is 4 and 7 added together.' Wrong! 47 is 4 tens (40) plus 7 ones (7), which equals 47, not 4 + 7 = 11.
Example:
47 = 4 tens + 7 ones = 40 + 7 = 47 ≠ 4 + 7 = 11
Learn to identify and correct common place value errors
47 is 4 and 7 added together
47 is 4 tens (40) plus 7 ones (7)
Remember: Remember: tens place means groups of 10, not individual numbers
32 = 3 + 2 = 5
32 = 30 + 2 = 32
Remember: The tens digit represents groups of 10, not individual numbers
Counting 23 as 2 + 3 = 5
23 = 2 tens + 3 ones = 20 + 3 = 23
Remember: Always think about place value: tens and ones have different values
