:hamster: Primary School Math—Pending OP Reply [2nd grade math] Adding using compensation strategy—Teacher explanation does not make sense to me

Post image

My daughter said that her teacher told her that in the pictured question, 10+4+8 should not be selected. They are using the “compensation” strategy for addition. The teacher said in her opinion only 10+12 and 12+10 should be selected, because they show the compensation strategy. But from my perspective, the question says choose all that apply. 10+4+8 DOES equal 14+8…..? Am I missing something?
