3RD GRADE?

Technically, I would say the Equivalence Property is the correct answer. But at third grade, I wonder if the teacher is focusing on the Additive property. Ask the student if he/she has heard these terms.
The properties are like identitive property or commutitive property and stuff like that but in this cause it is Identitive property. Trust me I'm in 5th grade and I'm a safety patrol.
identify the property 25+___=25
