How to Find the Missing Number in Addition Equations
FAQs on Missing Addend Worksheets for Class 2: 2-Digit + Three 1-Digit
1. What is a missing addend in math?
A missing addend is the unknown number in an addition problem that you need to find to make the equation true. For example, in the sum 15 + __ + 5 = 25, the blank space is the missing addend. Solving these problems helps build strong addition facts and problem-solving skills.
2. How do you solve missing addends in a Class 2 worksheet?
To solve a missing addend problem, you can follow these simple calculation strategies. For a sum like 27 + __ + 3 + 5 = 40, you would:
- Step 1: Add all the numbers you already know (27 + 3 + 5 = 35).
- Step 2: Subtract this total from the final answer (40 - 35 = 5).
- Step 3: The result (5) is the missing addend.
3. What is an example of a missing addend question from this worksheet?
A typical example from this Grade 2 maths worksheet involves a two-digit number and three single-digit numbers. For instance: 42 + 8 + __ + 4 = 60. Here, students must find the missing number that, when added to 42, 8, and 4, equals the sum of 60.
