Any addition sentence would be a number plus a number (and any other numbers added in a sequence, if applicable) with and "equal sign", or the words "is equal to" (or, "are equal to", if applicable"), or "equals", followed by the correct number.
Or, although rarely used, any addition sentence could be written as, say:
"The sum of "4 + 4" is equal to "8".
Any addition sentence can be written symbolically, such as: 4 + 2 = 6 . It is an "addition sentence" because it can be "pronounced" as:
"Four plus two equal six." __________________________ Also an addition sentence can correspond to a picture or diagram; the addition sentence does have to include any units. _____________________________________ In the case of a picture with 4 rows with 3 items in each row, one may think this seems like a multiplication problem; e.g. "3 x 4 = 12." __________________________________________ However, since the question being asked requires an addition sentence, we have to write this as a sum. We do this by using the conceptual principle that "3 *4" is like adding the number "3" (three) together, 4 (four) times. ____________________________________________ So, the answer would be: " 3 + 3 + 3 + 3 = 12 ." _____________________________________________
