Explanation: Being able to add is an essential math skill. You will be given an addition problem with a number missing. You will need to determine the missing number and then look at 4 addition problems. Choose the addition problem whose missing number is 'a match'.

Examples:

8 + _ = 11 Answer is '3'. Options: 5 + _ = 10, the missing number is '5', so it is 'not a match'. 3+_ = 9, the missing number is '6', so it is 'not a match'. 2 + _ = 5, the missing number is '3', so it is 'a match'.

5 + _ = 9 Answer is '4'. Options: 6 + _ = 8, the missing number is '2', so it is 'not a match'. 6 + _ = 10, the missing number is '4', so it is 'a match'.

Directions: For each problem, determine the missing number and then decide which answer will be 'a match'. Strive for accuracy and then strive to increase your speed. Good luck and enjoy the challenge!
