Subtraction Patterns Over Increasing Place Values (Within 1000)
Consider the subtraction pattern:
7 – 5 = _____
70 – 50 = _____
700 – 500 = _____
To complete this pattern, we find the first missing number.
7 ones – 5 ones = 2 ones
7 – 5 = 2
Now use this result to complete the pattern:
7 tens – 5 tens = 2 tens
70 – 50 = 20
7 hundreds – 5 hundreds = 2 hundreds
700 – 500 = 200
