Multiple Addends
Addends are numbers used in an addition problem, 2 + 3 = 5. Two and 3 are the addends, while 5 is the sum. Addition problems can have two or more addends, which can be single- or double-digit numbers.
Addition problems can have more than two addends. Problems like 8 + 2 + 3 = 13 have three addends that equal 13. In addition problems that have two-digit numbers, like 22 + 82, students must carry a number into the hundreds column to solve the problem, requiring the addition of yet another addend. Problems with three or more addends teach students the important concept of grouping numbers together to solve the problem quickly. Grouping is also important because it helps students break down large problems into smaller, manageable problems that reduce the chance of mathematical errors.
Missing addends are exactly as the name implies, meaning addends that are missing from the mathematical equation. A statement like 4 + _ = 8 contains one known addend, one unknown or missing addend and the sum. The purpose of learning addends like this is to introduce students to the basics of algebraic math. So if a student knows 5 + 6 = 11 and he sees a problem stating 5 + _ = 12, he can use his basic knowledge of addends and their sums to begin solving the problem. This is a useful skill for solving word problems.
