This task is appropriate for assessing student's understanding of repeated reasoning and generalizing that understanding to prepare them for deeper algebraic thinking needed in the expressions and equations domain. It will allow the teacher to assesses the level of understanding by analyzing how they solved the problem whether algebraically, concretely with picture representations or both. Those students who solved it more concretely may benefit from teacher guidance to the general algebraic solution. The Standards for Mathematical Practice focus on the nature of the learning 18 + 42 = 60. experiences by attending to the thinking processes and habits of mind that students need to develop in order to attain a deep and flexible understanding of mathematics.
