A worked example
14 - 6 = ___
Answer: 8
Subtract 4 first to reach 10, then subtract the remaining 2. That gives 8. Check: 8 + 6 = 14.
How to use these worksheets
These questions mix facts within 10 and within 20. Practice breaking a subtraction into a step to ten and a remaining step. Use the related addition fact as an independent check.
Watch for this
After subtracting enough to reach 10, subtract only the remaining amount. For 14 - 6, the remaining amount is 2.
