Dear Parents, We are starting a new unit and the focus is reading books by Kevin Henkes.
I
The second topic takes longer than and shorter than to a new level of precision by introducing the idea of a length unit. Centimeter cubes are laid alongside the length of an object as students learn that the total number of cubes laid end to end with no gaps or overlaps represents the length of that object (1.MD.2). The Geometric Measurement Progressions Document expresses the research indicating the importance of teaching standard before exploring non-standard units of measurement in this unit. The third topic explores the usefulness of measuring with similar units. Students measure the same objects from the second topic using two different non-standard units, toothpicks and small paper clips, simultaneously to measure one object and answer the question, “Why do we measure with same-sized length units?” (1.MD.2). They realize that using iterations of the same unit will yield consistent measure results. Students use standard units to answer such questions as, “How much longer is the pencil that the marker?” (1.OA.1). The fourth topic closes the unit as students represent and interpret data (1.MD.4). They collect data about their classmates and sort that information into three-categories. Using same-sized pictures on squares, students represent this sorted data so that it can be easily compared and described.
