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

These three sets “I Have…Who Has?” cards and accompanying printables are everything you need to introduce, practice, and assess your students’ understanding of multiplicative comparisons! The 3 sets of cards will provide your students with varied practice with interpreting multiplication as a comparison. Extend your students’ practice (or assess their mastery of interpreting comparative situations) with the included activity sheets. With these resources, your students will grow stronger in th

Help build your students’ proficiency with analyzing and interpreting whole number number lines with this set of task cards and printables. The 32 task cards will provide your students with the necessary practice to build their ability to understand and use number lines. Extend your students’ practice (or assess their level of mastery) with the two included activity sheets. With these resources, your students will grow stronger in their understanding of number lines. Included: • graphic r
