Students begin to develop their ability to reason comparatively in elementary school, learning to distinguish between multiplicative comparisons (21 is 3 times as big as 7) and additive comparisons (21 is 3 greater than 18), and such reasoning underlies the work with algebra and ratio & proportion that they will be doing in middle school and beyond. This bundle of resources – which includes 3 sets of task cards, 5 sets of I Have…Who Has? cards, 4 reference sheets, and 9 different assessment act
