Step-by-Step Solved Examples
Problem 1: ___ - 3 = 6
To find the missing starting number, or the minuend, you can use addition. Since the problem tells us that taking 3 away from a number leaves 6, we can add 6 and 3 together. Because 6 + 3 = 9, the missing number in the box is 9.
Problem 2: 16 - ___ = 2
In this problem, we know the starting total is 16 and the final answer is 2. To find the missing amount that was taken away, simply subtract the answer from the total. Since 16 - 2 = 14, the missing number that completes the equation is 14.
Problem 3: 19 - ___ = 16
This equation asks us what number needs to be subtracted from 19 to result in 16. You can solve this by counting back from 19 until you reach 16, which is 3 steps. Therefore, the missing subtrahend is 3, making the full sentence 19 - 3 = 16.
Teacher & Parent Tips
Encourage students to use number bonds to visualize how the three numbers in each subtraction sentence relate to one another. Using physical manipulatives, such as counting bears or blocks, can help children "see" the missing part of the equation by physically moving objects around. You might also suggest that students "check" their work by adding the two smaller numbers together to see if they get the larger number. This worksheet is an excellent tool for timed fluency drills, independent desk work, or as a helpful homework assignment to reinforce classroom lessons.
