What double adds to equal 100? 50 + 50 = 100 50 + 50

What double adds to equal 100? 50 + 50 = 100 50 + 50 Each of the fifties is called an addend. Addends are the numbers we add to equal a total. The total is called the sum. 49 + � = 100 If 50 plus 50 equals 100, what will we add to 49 to equal 100? 51 How do you know? We call 51 the missing addend.

� + 53 = 100 If 50 plus 50 equals 100, what will we

� + 53 = 100 If 50 plus 50 equals 100, what will we add to 53 to equal 100? 47 How do you know? We call 47 the missing addend. 25 + � = 100 If 50 plus 50 equals 100, what will we add to 25 to equal 100? 75 How do you know? We call 75 the missing addend.

The sum of the ones' digit is always 10 (or 0 if the ones' digits are 0's); the sum of the tens' digits is 9 (or 10 if the ones' digits are 0's)

Let's try these problems. Who would like to to us the first missing addend?
