The instructional materials reviewed for Kindergarten--Grade 2 do not meet the expectations for alignment and were not reviewed for usability. All grades in this grade band spend the majority of the time on the major work of the grade and align assessments to the standards. These grades also attend to the coherence in the standards. The materials use supporting content as a way to continue work with the major work of the grade. The materials include a full program of study that is viable content for a school year including 150 lesson and assessment days. This set of materials is consistent with the mathematical progression of learning set forth in the standards. All students are given extensive work on grade level problems and this work progresses mathematically. These instructional materials are visibly shaped by the cluster headings in the standards. Connections are made between domains and clusters within the grade level. Kindergarten, Grade 1 and Grade 2 were reviewed for Gateway 2, partially meeting the requirements for the aspects of rigor and the instructional use of the SMP. Overall the K-2  materials do not meet the requirements for alignment and, therefore, were not reviewed for usability.
