2nd Grade Addition Assessment

To solve the equation 10 + ___ = 15, we need to find the missing number that, when added to 10, equals 15. The correct answer is 5 because 10 + 5 = 15.

The given question asks for the sum of 24 and 0. When adding 0 to any number, the result remains the same number. Therefore, the sum of 24 and 0 is 24.

The correct answer is 12 because when you add 7 and 5 together, you get a sum of 12.

To find the missing number that when added to 2 equals 12, we can subtract 2 from 12. This gives us 10, which is the missing number. Therefore, the correct answer is 10.

The correct answer is 9 because when you add 3 and 6 together, the sum is 9.

To find the missing number that, when added to 7, equals 14, we can subtract 7 from 14. This gives us a result of 7. Therefore, the missing number is 7.

The question is asking for a number that, when added to 8, equals 16. The only number that satisfies this condition is 8.

To find the missing number that completes the equation 3 + __ = 11, we need to determine what number, when added to 3, equals 11. The correct answer is 8, as 3 + 8 = 11.

The correct answer is 30 because when you add 15 and 15 together, you get a sum of 30.

The numbers 25 and 15 are added together. The process of addition involves combining two or more numbers to find their total, which is called the sum. In this case, the sum of 25 and 15 is 40. This is a basic arithmetic operation that is fundamental to mathematics.
